The Role Of Photosynthetic Microbes In Agriculture And Industry

The photosynthetic microbes including microalgae and cyanobacteria are the most widespread photosynthetic organisms on Earth. These organisms thrive successfully in a wide range of ecological habitats, ranging from marine and freshwater to terrestrial environments. The short generation time and capability to fix the atmospheric N2 and cosmopolitan distribution make these organisms unique. Photosynthetic microbes such as cyanobacteria are used as biofertilizer for rice paddy and their application improves soil physico-chemical characteristics and the mineral nutrient status of the soil. However, in recent times they have been exploited for the production of several fine chemicals and biofuel. Due to their simple cellular organization, the bare minimum requirement of nutrients and ease of cultivation, recently the microalgae have been exploited and accompanied by the capacity to produce bio-energy, especially bio-diesel. Use of photosynthetic microbes in wastewater treatment has also generated considerable interest in the scientific community and industry at large. Bioremediation using photosynthetic microbes is an emerging area of research and the organisms accumulate or degrade several environmental contaminants and heavy metals. Because of the antagonistic properties, they are also a potential source of various bioactive compounds. In brief, the potential of photosynthetic microbes could be harnessed for economic viability and sustainability of agro-ecosystems. This book attempts to highlight the potential and prospects of the photosynthetic microbes for the welfare of mankind in view of the anticipated population explosion and global climate change.

Molecular Aspects of Plant Beneficial Microbes in Agriculture explores their diverse interactions, including the pathogenic and symbiotic relationship which leads to either a decrease or increase in crop productivity. Focusing on these environmentally-friendly approaches, the book explores their potential in changing climatic conditions. It presents the exploration and regulation of beneficial microbes in offering sustainable and alternative solutions to the use of chemicals in agriculture. The beneficial microbes presented here are capable of contributing to nutrient balance, growth regulators, suppressing pathogens, orchestrating immune response and improving crop performance. The book also offers insights into the advancements in DNA technology and bioinformatic approaches which have provided in-depth knowledge about the molecular arsenal involved in mineral uptake, nitrogen fixation, growth promotion and biocontrol attributes.

This book provides a cohesive overview of carbon concentrating mechanism (CCM) of photosynthetic microorganisms such as cyanobacteria and microalgae. This unique mechanism is by far the most spectacular physiological process in algal growth and productivity. Due to this fact, the study of CCM has captivated phycologists, algal molecular and cellular biologists, botanists, agriculturalists, crop growers, and most recently algal biofuel researchers, around the world. In the brief, the authors draw a contextual in-depth overview, on the basis of the latest findings, to develop an account of the core concepts regarding state-of-the-art of CCM. Subsequent chapters use this account to explore carbon concentrating mechanism of cyanobacteria and microalgae. They highlight the concise summaries of cutting-edge research and integrated industrial applications of photosynthetic microorganism based CO2 mitigation system, across a wide spectrum of energy and environment. The brief also presents sustainable perspectives of carbon concentrating mechanism in the context of current global energy and environmental challenges.

The use of microbial plant protection products is growing and their importance will strongly increase due to political and public pressure. World population is growing and the amount of food needed by 2050 will be double of what is produced now whereas the area of agricultural land is decreasing. We must increase crop yield in a sustainable way. Chemical plant growth promoters must be replaced by microbiological products. Also here, the use of microbial products is growing and their importance will strongly increase. A growing area of agricultural land is salinated. Global warming will increase this process. Plants growth is inhibited by salt or even made impossible and farmers tend to disuse the most salinated lands. Microbes have been very successfully used to alleviate salt stress of plants. Chemical pollution of land can make plant growth difficult and crops grown are often polluted and not suitable for consumption. Microbes have been used to degrade these chemical pollutants.

This book provides a comprehensive overview of the benefits of biofertilizers as an alternative to chemical fertilizers and pesticides. Agricultural production has increased massively over the last century due to increased use of chemical fertilizers and pesticides, but these gains have come at a price. The chemicals are not only expensive; they also reduce microbial activity in agricultural soils and accumulate in the food chain, with potentially harmful effects for humans. Accordingly, it is high time to explore alternatives and to find solutions to overcome our increasing dependence on these chemicals. Biofertilizers, which consist of plant remains, organic matter and microorganisms, might offer an alternative. They are natural, organic, biodegradable, eco-friendly and cost-effective. Further, the microbes present in the biofertilizers are important, because they produce nutrients required for plant growth (e.g., nitrogen, phosphorus, potassium), as well as substances essential for plant growth and development (e.g., auxins and cytokinins). Biofertilizers also improve the physical properties, fertility and productivity of soil, reducing the need for chemical fertilizers while maintaining high crop yield. This makes biofertilizers a powerful tool for sustainable agriculture and a sustainable environment. The book covers the latest research on biofertilizers, ranging from beneficial fungal, bacterial and algal inoculants; to microbes for bioremediation, wastewater treatment; and recycling of biodegradable municipal, agricultural and industrial waste; as well as biocontrol agents and bio-pesticides. As such, it offers a valuable resource for researchers, academics and students in the broad fields of microbiology and agriculture.
