The book revisit in depth scope of agroindustrial waste for enhancement in biofuels production on practical ground. It explores and discusses various cellulose rich agro-wastes along with low cost, advance technology based options for sustainable biofuels production. Lignocellulosic biomasses are potential producer of biofuels due to renewable nature and huge occurrence. Cellulose is the main polymeric component of these biomasses apart from lignin and hemicellulose. It can be converted into fermentable sugars using cellulase enzyme which can be further converted into the renewable energy sources such as biohydrogen, bioethanol, biogas and butanol. Chapters in this title provide exclusive and critical analysis of specific biofuels production process only from lignocellulosic biomass, based on their type, property, availability, cost and most important sugar or cellulose content along with the simplest process search for converting these biomasses into biofuels to make overall process more simple and economical.It is a useful guide for academician and environmentalist who are working to explore feasible advantages associated with these kinds of waste management and their effective valorization.

This book aims to inform readers about the recent developments in bioenergy and biofuels covering current issues from an interdisciplinary approach. It will also feature coverage of anticipated future trends related to each particular biofuel. Chapters will consist of original research presented by world class experts in their respective fields. A number of interdisciplinary areas will be incorporated such as Energy & Fuels, Biotechology, Genomics, Economics, Optimization, Chemical Engineering, Mechanical Engineering and Algae Science. Examples will relate to a matrix of biofuel and energy types such as bioethanol, biobutanol, and biomethane.

Microbial oxidative enzymes are in need of today and in the future also. Several microbial oxidative enzymes are being used by various sectors like food, agriculture, medicine, detergents, leather, paper, etc. Microbial oxidative enzymes are a natural product, hence, the application of these enzymes is eco-friendly. Oxidative enzymes from microbes like bacteria, and fungi will be helpful in numerous applications including plant-soil health management, and waste treatments. This book will be more informative as well as useful for related industries and end users and will be of great value to those interested in present-day research on oxidation-reduction enzymes. In the coming years, this book will be a game changer for the field of oxidative enzyme development and its applications.

The increased industrialization and motorization has led to a steep rise for the demand of petroleum products. Petroleum based fuels are obtained from limited reserves. It is estimated that the known crude oil reserves could be depleted in less than 50 years at the present rate of consumption. Hence, it is necessary to look for alternative fuels. An entire branch of biotechnology, referred to as "white biotechnology", centers on the bio production of fuels and chemicals from renewable sources. About 90% of the current biofuel market is represented by biodiesel and bioethanol. Biodiesel is an efficient, nontoxic, biodegradable and clean burning fuel alternative to petroleum fuels which runs in unmodified diesel engines. This paper reviews approaches to microbial synthesis of biodiesel, focusing on the role of synthetic biology as an enabling technology in the design of optimal cell factories.

Cyanobacteria constitute the most widely distributed group of photosynthetic prokaryotes found in almost all realms of the earth and play an important role in Earth's nitrogen and carbon cycle. The gradual transformation from reducing atmosphere to oxidizing atmosphere was a turning point in the evolutionary history of the earth and made conditions for present life forms possible. Cyanobacteria: From Basic Science to Applications is the first reference volume that comprehensively discusses all aspects of cyanobacteria, including the diverse mechanisms of cyanobacteria for the advancement of cyanobacterial abilities, towards higher biofuel productivity, enhanced tolerance to environmental stress and bioactive compounds and potential for biofertilizers. - Describes cyanobacterial diversity, stress biology, and biotechnological aspects of cyanobacteria - Explores the global importance of cyanobacteria - Provides a broad compilation of research that deals with cyanobacterial stress responses in both controlled laboratory conditions as well as in their natural environment

This book presents research on biomass pretreatments, which are a fundamental part of bioethanol fuel production to make biomass more accessible. This book also includes an introductory section on the bioethanol fuels. Bioethanol Fuel Production Processes. I: Biomass Pretreatments is the first volume in the Handbook of Bioethanol Fuels (Six-Volume Set). The primary pretreatments at the macro level are the biological chemical, hydrothermal, and mechanical pretreatments of the biomass. It also has an introductory section on the biomass pretreatments at large for bioethanol fuel production. The major pretreatments at the micro level are the enzymatic and fungal pretreatments of the biomass as the biological pretreatments, acid, alkaline, ionic liquid, and organic solvent pretreatment pretreatments of the biomass as the chemical pretreatments, steam explosion and liquid hot water pretreatments of the biomass as the hydrothermal pretreatments, and milling, ultrasonic, and microwave pretreatments of the biomass as the mechanical pretreatments. The first volume also indicates that a wide range of pretreatments stand alone or in combination with each other fractionate the biomass to its constituents of cellulose, lignin, and hemicellulose and improve both sugar and bioethanol fuel yield, making this bioethanol fuel more competitive in relation to crude oil- and natural gas-based fossil fuels. This first volume is a valuable resource for the stakeholders primarily in the research fields of energy and fuels, chemical engineering, environmental science and engineering, biotechnology, microbiology, chemistry, physics, mechanical engineering, agricultural sciences, food science and engineering, materials science, biochemistry, genetics, molecular biology, plant sciences, water resources, economics, business, management, transportation science and technology, ecology, public, environmental and occupational health, social sciences, toxicology, multidisciplinary sciences, and humanities among others.
