Abstract

Today more than 70% of energy is generated by coal-based thermal power plants. Indian coal contains about 40% ash, these power plants generate enormous amounts of fly ash, which is dumped in the nearby areas. This creates not only economy constraints but also imposes serious environmental problems, which are the potential hazards to the ecosystem. However, recent attempts in India and abroad are being made for biological association of fly ash e.g. in soil improvement, in wasteland management and also as a source of essential plant nutrients for nutrient deficient soil in terrestrial eco-system and agro-ecosystem. Fly ash has been found to have manifold advantages in agriculture especially in modification of soil texture and bulk density, in optimization of soil pH, in improvement of water holding capacity of soil, in the improvement of yield as a micronutrient supplement to soil and in creation of conducive condition for better plant growth. In this article utilization of fly ash along with VAM fungi and other microbes especially nitrogen fixers and phosphate solubilizers in removing the constraints of salt affected soils has been discussed.

Insecticides are one of the key control measures to combat the insect pests for sustainable agricultural production in the world. Synthetic insecticides have been only strategy to control the resurgent and resistant insect population in of high value crops not only in India but also in the world. The advent of synthetic insecticides in the mid-20th century made the control of insect and other arthropod pests easy and much more effective, and such chemicals remain essential in modern agriculture despite their environmental issues.

Abstract

Anoxygenic phototrophic bacteria (APB) are having the genetic potential of converting radiant energy into chemical energy useful for growth and metabolic activities without evolving oxygen. They are physiologically, metabolically and phylogenetically versatile group of organism spread in five distinct phyla; Proteobacteria (purple bacteria), Chlorobi (green-sulfur bacteria), Chloroflexi (green non-sulfur bacteria), Fir micutes (heliobacteria) and Acidobacteria. Different group of APB harbors distinct photosynthetic pigments, carotenoids, and a photosynthetic reaction center. These group of bacteria succeeds in a natural environment with light availability and presence of anoxic conditions as the pigment, and the molecular oxygen inhibits bacteriochlorophyll synthesis whereas few APB can grow in hypooxic as well as in aerobic conditions. Calvin-Benson-Bassham (CBB) pathway, reverse tricarboxylic acid (rTCA) cycle, and hydroxypropionate cycle are reported pathways for carbon assimilation in APB to fix carbon dioxide. Photosynthesis occurs in either intracytoplasmic membrane (ICM) or membrane bound chlorosomes and in the cytoplasm for few APB. APB have a wide range of potential applications including removal of H₂S from wastewater and gas streams, hydrogen production, degradation of xenobiotic, toxic metals and radioisotopes, work as host for the production of challenging membrane proteins, source of carotenoids and terpenoids, single cell protein, extensive applications in agriculture and production of bioactive compounds with antimicrobial, antioxidant and anticancer activity. The chapter is focused on the diversity of different types of APB, habitats, their growth requirements, photosynthetic machinery and biotechnological applications of APB.

The Government of India has established a comprehensive institutional framework to promote natural farming through various schemes and initiatives that provide financial support, technical assistance, and policy backing to farmers transitioning from conventional to sustainable agricultural practices. These government interventions represent a strategic shift toward recognizing natural farming as a viable solution to address environmental degradation, input cost escalation, and farmer distress while enhancing agricultural sustainability and food security. The National Mission on Natural Farming (NMNF) represents the flagship government initiative specifically designed to promote chemical-free and climate-smart agriculture across the country. The Union Cabinet approved the National Mission on Natural Farming (NMNF) on 25th November 2024 as a standalone Centrally Sponsored Scheme under the Ministry of Agriculture & Farmers’ Welfare, with a target to initiate one crore farmers into natural farming over the next two years. The mission builds upon the earlier Bhartiya Prakritik Krishi Paddhati (BPKP)

The integration of all components of community mobilization for natural farming represents a complex, multidimensional process that requires systematic coordination across social, institutional, technological, and economic domains to create coherent and sustainable agricultural transformation. This integration transcends simple coordination of activities to encompass the development of synergistic relationships between different mobilization elements that collectively enhance the effectiveness, sustainability, and scalability of natural farming adoption while building resilient communities capable of ongoing innovation and adaptation. Systems thinking approaches provide the conceptual foundation for integration by recognizing that community mobilization components function as interconnected elements within broader social-ecological systems rather than isolated interventions. This perspective emphasizes understanding the relationships, feedback loops, and emergent properties that arise from component interactions while designing interventions that strengthen system coherence and resilience. Systems approaches require analyzing how training programs, institutional support, communication strategies, and policy frameworks influence each other 

Modern biological systems cannot be fully understood through a single molecular layer. This chapter examines the integration of genomics, transcriptomics, proteomics, and metabolomics to obtain a comprehensive systems-level understanding of biological processes. It explains the role of each omics discipline and shows how their combined analysis can connect genetic information, gene expression, protein activity, metabolic states, and phenotypic outcomes. The chapter discusses the need for multi-omics integration, computational and network-based analysis, and systems biology workflows. Applications include disease diagnosis, precision medicine, crop improvement, stress tolerance, biotechnology, metabolic engineering, synthetic biology, and environmental research. Multi-omics integration provides improved biological interpretation, biomarker discovery, pathway prediction, and therapeutic target identification.

Since the mid 1980s, genome identification and selection has progressed rapidly with the help of PCR technology. A large number of marker protocols that are rapid and require only small quantities of DNA have been developed. Three widely-used PCR-based markers are RAPDs (Williams et al., 1990), SSRs or microsatellites (Tautz, 1989), and AFLPs (Vos et al., 1995). Each marker technique has its own advantages and disadvantages. RAPD markers are very quick and easy to develop (because of the arbitrary sequence of the primers) but lack reproducibility (Karp et al., 1997; Hansen et al., 1998; Jones et al., 1999; Virk et al., 2000). AFLP has medium reproducibility but is labour intensive and has high operational and development costs (Karp et al., 1997). Microsatellites are specific and highly polymorphous (Karp et al., 1997, Jones et al., 1999), but they require knowledge of the genomic sequence to design specific primers and, thus, are limited primarily to economically important species.

The choice of a molecular marker technique depends on its reproducibility and simplicity. The best markers for genome mapping, marker assisted selection, phylogenic studies, and crop conservation have low cost and labour requirements and high reliability. Since 1994, a new molecular marker technique called inter simple sequence repeat (ISSR) has been available (Zietkiewicz et al., 1994). ISSRs are semiarbitrary markers amplified by PCR in the presence of one primer complementary to a target microsatellite. Amplification in the presence of nonanchored primers also has been called microsatellite-primed PCR, or MP-PCR, (Meyer et al., 1993).

Abstract

Describes the genesis, organization and Internet representation of International Patent Classification (IPC). Provides the outline of seventh edition and useful URLs related to it.

Keywords: International Patent Classification, Patent Classification, Classification, Internet representation

Introduction

The International Patent Classification, commonly known as the IPC, is based on an international multi-lateral treaty administered by World Intellectual Property Organization (WIPO). This treaty is called the Strasbourg Agreement concerning the IPC, which was concluded in 1971 and came into force on October 7, 1975. The Agreement aimed to overcome the difficulties caused by using diverse national patent classification system. The common classification system defined by the Agreement is applied to patent and utility model documents. The Agreement is open to States party to the Paris Convention for the Protection of Industrial Property.

Biotechnology plays a very important role in agriculture as a result of its ability to modify microorganisms, plants, animals, and agricultural processes. The umbrella of microbial technology in agriculture covers numerous scientific activities, ranging from production of biofertilizers to that of microbial pesticides; from biological nitrogen fixation to lignocellulose degradation; from production of biomass and biofuels to transgenic plants. Terrestrial ecosystem contains an important dynamic living matrix termed soil, which is critical for agricultural production and food security. Soil forms the medium for growth and maintenance of a variety of plant species. Soil is considered a store house of microbial activity, though the space occupied by living microorganisms is estimated to be less than 5% of total space.

As global climate change becomes an increasingly urgent concern, the search for sustainable and renewable energy sources has intensified. Among the alternatives to fossil fuels, biofuels have emerged as a promising solution due to their potential to reduce greenhouse gas emissions and dependence on petroleum. Biofuels are derived from organic matter, such as crops, agricultural residues and other biomass, which can be converted into energy sources like ethanol, biodiesel, and biogas. For instance, crops like corn and soybeans contain oil extracts that can be processed into biofuels, offering a renewable and environmentally friendly alternative to traditional fossil fuels (Demirbas, 2009). However, the potential of biofuels extends beyond these conventional sources, as researchers explore a wide range of organic materials that can be sustainably regrown and harvested, minimizing ecological impacts (Naik et al., 2010). Biofuels have gained significant importance in both developed and developing economies, driven by their potential to enhance energy security and reduce carbon footprints. In 2023, the United States led global biofuel production with 15,550 million gallons, followed by Brazil with 8,260 million gallons. India ranked third, producing 1,430 million gallons of bioethanol and achieving an E11.7 blend rate during the 2022–2023 period. This blend was sourced from various feedstocks, including sugarcane juice (5%), cane molasses (5%), and damaged food grains (DFG) (1.7%). Historically, India’s ethanol production has relied heavily on sugarcane molasses, but the National Biofuel Policy (NBP) of 2018 has been instrumental in promoting the use of biofuels to reduce fossil fuel dependence, mitigate greenhouse gas emissions, and strengthen energy security (Ministry of Petroleum and Natural Gas, 2018). India, the third-largest energy-consuming nation globally, faces considerable challenges due to its heavy dependence on imported oil, posing risks to both economic stability and strategic security. With its share of global energy consumption projected to double by 2050, the country is actively seeking domestic alternatives to curb this reliance. Ethanol, produced within India, has emerged as a viable substitute. Since its initial pilot in 2001, ethanol-blended petrol has demonstrated notable environmental advantages, with every 10 million liters reducing CO2 emissions by 8,000–17,000 tonnes compared to conventional

1.1 An overview of biomass

Biomass is an abundant and renewable energy source that has the potential to meet the growing need for clean and sustainable energy solutions. This chapter provides an overview of biomass, its potential, and conversion technologies, which include various techniques for transforming biomass into useful forms of energy such as heat, electricity, and biofuels.

Biomass is an organic substance that can be obtained from agricultural crop waste, forest waste, animals, and microorganisms. It can be used as an energy source or a primary material in various applications. The energy in biomass is derived from photosynthesis, in which plants convert sunlight, carbon dioxide, and water into organic matter.

Introduction
The characteristics of bacteria used in the study and identification of bacteria depend upon the behavior of populations or cultures rather than of individual organisms. Nutrient materials provided in a form, suitable for growth, are known as culture media. A Growth Media or culture medium is a liquid or gel designed to support the growth of microorganisms or cells.
I. Types of Culture Media
Different types of culture media may be used for cultivation of microorganisms such as liquid, solid and semi-solid.
i) Liquid Culture Media: Includes nutrient broth, Glucose broth, litmus milk etc. these media are used for the preparation of large number of microorganisms, fermentation studies and various other tests.
ii) Solid Media: A little agar, gelatin or silica gel; is added to a liquid medium to impart a degree of firmness to it. Nutrient agar, Blood agar, etc. are examples of solid media that are used for developing surface colony growth of bacteria and mold.
iii) Agar Slant Media: Test tubes or small bottles containing about 5ml. of solid medium, e.g. nutrient agar, dissolved and allowed to cool in a sloping position.
iv) Stab Media: Tubes or bottles containing agar medium are allowed to solidify in the upright position.
v) Semi solid Media: These are more jelly like due to lower percentage of the solidifiers. These media are particularly used for determining motility of bacteria.

Intellectual Property Rights (IPR) refer to the legal rights granted to creators, inventors, and innovators for their intellectual creations. These rights enable individuals or organizations to control and benefit from the use of their creations for a certain period. In the era of rapid advancements in biotechnology and molecular biology, IPR has emerged as a cornerstone in protecting and commercializing innovations in plant genetics, genetic engineering, bioproducts, and molecular tools.
The concept of IPR is rooted in the recognition that ideas, like physical property, hold economic value and deserve legal protection. IPR plays a pivotal role in encouraging innovation, fostering technology transfer, promoting research investment, and ensuring economic returns to developers. In biotechnology, IPR has direct implications on transgenic technologies, bioinformatics, novel genes, enzymes, diagnostic kits, and biopharmaceuticals.
1.1 Evolution and Historical Background of IPR
1.1.1 Introduction
The concept of Intellectual Property Rights (IPR) has evolved over centuries as a legal framework to protect creations of the human intellect. While the terminology “intellectual property” is relatively modern, the underlying idea—that inventors, artists, and creators deserve recognition and protection for their innovations—has ancient roots. In the context of modern biotechnology, IPR serves not only as a legal safeguard but also as a vital tool to stimulate innovation, secure investments, and promote equitable commercialization.
Understanding the historical trajectory of IPR helps contextualize contemporary debates on the ownership of genetic resources, traditional knowledge, and the ethical implications of patenting life forms.

exhibits alternation of generations - has a distinctive diploid (sporophyte) and haploid (gametophyte) phase.

Soil represents a medium or substrate in which numerous microorganisms live and bring about a great variety of processes that are responsible for the continuation of the cycle of life in nature. The numerous living forms which spend their life in the soil, ranging from submicroscopic forms to the lower animal forms. With the growing recognition of the numerous processes carried out by the microorganisms in the soil there gradually emerged a branch of microbiology, which came to known as soil microbiology. It is a branch of soil science concerned with soil-inhabiting microorganisms and their functions and activities.

Since soil microbiology concerns soil microorganisms and their processes it is closely associated with soil biochemistry. Medical bacteriologists are interested in the soil as a medium for the growth and survival of disease-producing organisms. Agricultural chemists are also interested in the soil processes that result from the activities of microorganisms. General bacteriologists, zoologists, botanists are interested in a certain special group of organisms found in the soil. Recently, soil microbiology has expanded to include the study of the role of soil microorganisms in genetic engineering, in the biological control of pests and diseases, the degradation of pollutants, production and destruction of radioactive gases and its transfer. Thus microbial participation in several important processes emphasizes that soil microbiology has become a global science.

1.1 Introduction to Sustainable Energy
The idea of sustainable energy has come to light in the twenty-first century as the globe struggles with rising energy demands, environmental degradation, and the menacing threat of climate change. It offers hope and a way forward for a more promising future. A major change in the production, distribution, and consumption of energy resources is what sustainable energy entails. It is a paradigm that includes a range of clean and renewable energy sources, technologies, and methods with the goal of supplying our energy demands with the least amount of harm to the environment (Andrews and Shabani, 2014). 1.2 Importance of Sustainable Energy Sources Sustainable energy is of paramount importance due to several interconnected reasons listed below and shown in Figure 1:
1.2.1 Environmental Concerns: For many years, conventional fossil fuelbased
energy sources like coal, oil, and natural gas have formed the foundation of our energy system. But as they burn, greenhouse gases (GHGs) mostly carbon dioxide (CO2) are released into the environment (Hosseini and Wahid, 2016). These greenhouse gases are the main causes of climate change, which raises global temperatures, brings on harsh weather, and raises sea levels. Conversely, sustainable energy sources are crucial for reducing climate change because they emit little or no greenhouse gases when in use.
1.2.2 Finite Nature of Fossil Fuels: Because fossil fuels are limited resources,
their stocks are running out quickly. The task that follows is to ensure that future generations have access to economical and dependable energy sources. Because they are renewable or endless, sustainable energy sources provide a solution to the problem of energy security (Su-Ungkavatin et al., 2023).
1.2.3 Economic Benefits: Making the switch to renewable energy can be
very profitable. It can improve national energy security and lessen trade deficits by fostering innovation, generating jobs, and lowering dependency on energy imports. Furthermore, because they frequently have lower operating and maintenance costs than fossil fuel-based systems, sustainable energy technologies can result in cost savings over time (Shafiei et al., 2015).
