Lignocellulose Biotechnology by Ramesh Chander Kuhad,Ajay Singh Pdf

The agricultural and forestry processing wastes (lignocellulosics) are an important material resource and energy source. However, if untreated they can pose a danger to the environment and potentially valuable resources. Microorganisms contribute significantly to solving the problem of biomass degradation, its recycling and conservation. In the recent years, an increasing interest shown by the textile, food, feed & pulp, and paper industries in the microbial and enzymatic processes has triggered in-depth studies of lignocellulolytic microorganisms and their enzymes. Moreover, the advent of recombinant DNA technology in the late 1970s further paved the way for developing technologies based on lignocellulolytic microbes and enzymes. Lignocellulose Biotechnology presents a comprehensive review of the research directed towards environmentally friendly agricultural and forest by-products. The book comprises 22 chapters, divided in four sections. It deals with a wide range of topics including biodiversity of lignocellulose degrading microorganisms and their enzymes, molecular biology of biodegradation of lignin, characterization of lignocellulolytic enzymes, bioconversion of plant biomass to produce enzymes, animal feed, bioethanol and industrial applications of lignocellulolytic enzymes. The chapters dealing with industrial applications also address current biotechnological approaches in lignocellulose bioconversion to value added products. This book is essential for students, researchers, scientists, and engineers working in the fields of environmental microbiology, environmental biotechnology, life sciences, waste management, and biomaterials.

Lignocellulose Conversion by Vincenza Faraco Pdf

Bioethanol has been recognized as a potential alternative to petroleum-derived transportation fuels. Even if cellulosic biomass is less expensive than corn and sugarcane, the higher costs for its conversion make the near-term price of cellulosic ethanol higher than that of corn ethanol and even more than that of sugarcane ethanol. Conventional process for bioethanol production from lignocellulose includes a chemical/physical pre-treatment of lignocellulose for lignin removal, mostly based on auto hydrolysis and acid hydrolysis, followed by saccharification of the free accessible cellulose portions of the biomass. The highest yields of fermentable sugars from cellulose portion are achieved by means of enzymatic hydrolysis, currently carried out using a mix of cellulases from the fungus Trichoderma reesei. Reduction of (hemi)cellulases production costs is strongly required to increase competitiveness of second generation bioethanol production. The final step is the fermentation of sugars obtained from saccharification, typically performed by the yeast Saccharomyces cerevisiae. The current process is optimized for 6-carbon sugars fermentation, since most of yeasts cannot ferment 5-carbon sugars. Thus, research is aimed at exploring new engineered yeasts abilities to co-ferment 5- and 6-carbon sugars. Among the main routes to advance cellulosic ethanol, consolidate bio-processing, namely direct conversion of biomass into ethanol by a genetically modified microbes, holds tremendous potential to reduce ethanol production costs. Finally, the use of all the components of lignocellulose to produce a large spectra of biobased products is another challenge for further improving competitiveness of second generation bioethanol production, developing a biorefinery.

Grand Challenges in Fungal Biotechnology by Helena Nevalainen Pdf

This volume provides a comprehensive overview of the major applications and potential of fungal biotechnology. The respective chapters report on the latest advances and opportunities in each topic area, proposing new and sustainable solutions to some of the major challenges faced by modern society. Aimed at researchers and biotechnologists in academia and industry, it represents essential reading for anyone interested in fungal biotechnology, as well as those working within the broader area of microbial biotechnology. Written in an accessible language, the book also offers a valuable reference resource for decision-makers in government and at non-governmental organizations who are involved in the development of cleaner technologies and the global bioeconomy. The 21st century is characterized by a number of critical challenges in terms of human health, developing a sustainable bioeconomy, facilitating agricultural production, and establishing practices that support a cleaner environment. While there are chemical solutions to some of these challenges, developing bio-based approaches is becoming increasingly important. Filamentous fungi, ‘the forgotten kingdom,’ are a group of unique organisms whose full potential has yet to be revealed. Some key properties, such as their exceptional capacity to secrete proteins into the external environment, have already been successfully harnessed for the production of industrial enzymes and cellulosic biofuels. Many further aspects discussed here –such as feeding the hungry with fungal protein, and the potential applications of the various small molecules produced by fungi –warrant further exploration. In turn, the book covers the use of fungal cell factories to produce foreign molecules, e.g. for therapeutics. Strategies including molecular approaches to strain improvement, and recent advances in high-throughput technologies, which are key to finding better products and producers, are also addressed. Lastly, the book discusses the advent of synthetic biology, which is destined to greatly expand the scope of fungal biotechnology.

The book also provides the knowledge on how to develop safe, more efficient, sustainable, and economical integrated processes for enhanced conversion of lignocellulosic feedstocks to liquid and gaseous biofuels. Finally the book describes how to perform the techno-economical and life-cycle assessments of new integrated processes involving extremophiles. These modeling exercises are critical in addressing any deficiencies associated with the demonstration of an integrated biofuels and value-added products production process at pilot scale as well as demonstration on the commercialization scale.

Extremophilic Enzymatic Processing of Lignocellulosic Feedstocks to Bioenergy by Rajesh K. Sani,R. Navanietha Krishnaraj Pdf

This book introduces fundamentals of enzymatic processes, various renewable energy resources and their pretreatment processes. It presents in-depth review of extremophilic enzymes (e.g., Cellulases, Xylanases, Lytic Polysaccharide Monooxygenases, Amylases, Ligninases, Pectinases, Esterases, and Chitinases) which can be used in several biotechnological processes. In addition, the authors present expert knowledge on how to engineer enzymes for enhanced conversion of lignocellulosic feedstocks to biofuels.Extremozymes play important roles in many kinds of bioprocessing e.g., in conversion of non-food biomass into usable power. Existing enzymatic technologies, including hydrolysis of lignocellulose into sugars, have several limitations such as they have very slow enzymatic hydrolysis rates, yields low products, requires high dosages of enzymes, and are sensitive to microbial contamination problems. These limitations could be overcome using extremophilic enzymes.
