Biostimulants (a diverse class of compounds including substances or microorganisms) are helpful in sustainable plants growth and development. They accelerate plant growth, yield, and chemical composition even under unfavorable conditions. The main biostimulants are nitrogen-containing compounds, humic materials, some specific compounds released by microbes, plants, and animals, various seaweed extracts, bio-based nanomaterials, phosphite, silicon, and so on. Additionally, new generation products and bioproducts are being developed for sustainable plant growth and protection. Some research works in the area of biotechnology and nanobiotechnology have shown improved sustainable plant growth and production. The protective roles of biostimulants are varied depends on the compound and plant species. Exposure of biostimulants have shown accelerated plants growth and developmental processes for instance, manage stomatal conductance and rate of transpiration, and increase rate of photosynthesis etc. They also increased crop plants immune systems against the adverse situation. Thus, use of innovations of new generation biostimulants also enhance plant production systems, through a significant reduction of synthetic chemicals such as pesticides and fertilizers. Moreover, bioinoculants commercial products obtained from seaweed extract, humic acids, amino acids, fulvic acids, and some microbial inoculants have shown their potential role in adventitious root induction in plants. Microbial inoculants or microbial-based biostimulants, as a promising and eco-friendly technology, can be widely used to address environmental concerns and fulfill the need for developing sustainable or modern agriculture practices. They have great potential to elicit plant tolerance to various climate change-related stresses and thus enhance plant growth and overall performance-related features. However, for successful implementation biostimulants-based agriculture in the field under changing climate conditions, an understanding of plant functions and biostimulants interaction or action mechanisms coping with various abiotic as well as biotic stresses at the physicochemical, metabolic, and molecular levels is required. Mycorrhizae are beneficial fungi that form symbiotic associations with plants and aid in plant development, disease resistance, and soil health is well established. Similarly, phyllospheric microbiome are known to possess different plant growth promotion attributes like nitrogen fixation, phosphate solubilization, biocontrol activity, and increase plant resistance towards abiotic stresses. The plant growth promotion traits possessed by these phyllospheric microbiota can be judiciously harbored for phyllospheric and rhizospheric engineering. The engineered phyllospheric and rhizospheric microbiome can increase the plant growth and productivity, thereby, can act as a driving force for increasing the agricultural production in a sustainable manner. Taken together, this book aims to contribute to the recent understanding associated with the various role and application of biostimulants on different plant for their sustainable growth and management. Discusses our current understanding of, and advances in, biostimulants, along with their application in plants growth performance and overall management Explores new techniques, new generation products, and bioproducts Highlights the role of seaweed extract, humic acids, protein hydrolysates, amino acids, melatonin, paramylon, fulvic acids, microbial inoculants (phyllospheric and rhizospheric), and more

Focusing on current and future uses of microbes as production organisms, this practice-oriented textbook complements traditional texts on microbiology and biotechnology. The editors have brought together leading researchers and professionals from the entire field of industrial microbiology and together they adopt a modern approach to a well-known subject. Following a brief introduction to the technology of microbial processes, the twelve most important application areas for microbial technology are described, from crude bulk chemicals to such highly refined biomolecules as enzymes and antibodies, to the use of microbes in the leaching of minerals and for the treatment of municipal and industrial waste. In line with their application-oriented topic, the authors focus on the "translation" of basic research into industrial processes and cite numerous successful examples. The result is a first-hand account of the state of the industry and the future potential for microbes in industrial processes. Interested students of biotechnology, bioengineering, microbiology and related disciplines will find this a highly useful and much consulted companion, while instructors can use the case studies and examples to add value to their teaching.

Green technologies are no longer the “future” of science, but the present. With more and more mature industries, such as the process industries, making large strides seemingly every single day, and more consumers demanding products created from green technologies, it is essential for any business in any industry to be familiar with the latest processes and technologies. It is all part of a global effort to “go greener,” and this is nowhere more apparent than in fermentation technology. This book describes relevant aspects of industrial-scale fermentation, an expanding area of activity, which already generates commercial values of over one third of a trillion US dollars annually, and which will most likely radically change the way we produce chemicals in the long-term future. From biofuels and bulk amino acids to monoclonal antibodies and stem cells, they all rely on mass suspension cultivation of cells in stirred bioreactors, which is the most widely used and versatile way to produce. Today, a wide array of cells can be cultivated in this way, and for most of them genetic engineering tools are also available. Examples of products, operating procedures, engineering and design aspects, economic drivers and cost, and regulatory issues are addressed. In addition, there will be a discussion of how we got to where we are today, and of the real world in industrial fermentation. This chapter is exclusively dedicated to large-scale production used in industrial settings.
