This book was released on 2018 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: Amid growing concerns of carbon emissions, finding green and renewable sources of fuels and chemical feedstocks has been gaining attention. Pyrolysis, a process that can convert lignocellulosic biomass into oils usable as fuels or chemical feedstocks, holds promise but suffers from the drawbacks of high energy demands and low-quality products. These drawbacks are likely due, in part, to a compound called lignin. Lignin, which comprises roughly 20% of lignocellulosic biomass, is the most difficult biomass constituent to thermally break down and interferes with the pyrolysis of the more amenable cellulose. Three species of lignolytic fungi were used to treat three lignocellulosic feedstocks in an effort to improve the quality of the pyrolysis oils and reduce the peak mass loss temperature of pyrolysis. Results show that fungal treatment can dramatically alter the composition of produced bio-oils, including the production of new compounds, while also altering the thermal characteristics of pyrolysis. In addition to fuel and chemical production from lignocellulose, biofuel production from an agricultural co-product was also examined. An environmentally-isolated microbe was identified and found to produce high levels of lipids when grown on Sugar Beet Molasses (SBM), which is an agricultural co-product. The growth rate and lipid production of this microbe when grown on SBM were examined for the production of biodiesel.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Use of biomass as feedstock for the production of carbon-based fuels and chemicals represents an essential component of the global strategy to attain sustainable and circular industrial economies. Current strategic objectives for biomass conversion technologies focus on enhancing cost competitiveness through, for example, the use of cheaper feedstocks (e.g. lignocellulosic wastes). However, adoption of lignocellulosic biomass as substrate will only be possible after addressing the inefficiencies and costs which stem from the additional processing necessitated by the compositional complexity of lignocellulosic materials. Nature, wherein the recycling of lignocellulosics is an essential ecological process, may offer strategies for engineers and scientists to emulate. Fungi, particularly filamentous fungi, are well-known for their role as material recyclers in the natural carbon cycles and, as such, are intriguing for use in biomass-conversion, or biorefining processes. Concerning the products of fungal biotransformations, the number of potential products is proportional to the number of metabolites associated with a given organism; and these metabolic products remain largely underexplored or altogether unidentified. Therefore, a method for screening and evaluating a large number of products that may be obtained from fungal biotransformation of various biomass feedstocks was developed as part of the study described herein. Identified among the products were valuable chemicals, such as those described in two recent US Department of Energy surveys, including furans and organic acids. In addition to these "top chemical opportunities", substantial production of bio-pigments was also observed. Of the feedstocks investigated, a simulated food-waste feedstock was associated with the highest pigment production and was thus further investigated for maximal pigment production. To that end, an optimized extraction method was employed and, following this, a novel strategy was explored involving co-culturing of multiple strains of fungi together in a single conversion reaction. It was found that co-culturing the pigment-producing fungus with a specific second species elicited significantly more pigment production vis-à-vis the pigment-producing species alone. 2,5-furandicarboxylic acid (FDCA), a compound of industrial interest for use as a replacement for terephthalic acid in polymer production, was also identified among the fungal biotransformation products of apple pomace feedstock. Since FDCA is mainly produced via oxidation of 5-hydroxymethylfurfural (HMF), itself a carbohydrate-derived product, the process of using filamentous fungi for converting HMF into FDCA was more closely investigated. Several industrially relevant strains of filamentous fungi, including the strain used throughout this project (Talaromyces sp. NRRL 2120), were screened for oxidative activity on HMF. It was found that multiple strains of fungi readily performed one oxidation on HMF (i.e. converted HMF into its acid counterpart) but accumulated very little, if any, FDCA under the given reaction conditions. To enable additional oxidation steps, a chemo-biocatalytic cascade involving the best-performing fungal strain coupled with an enzyme/mediator system was devised. This system enabled full conversion of HMF into FDCA and achieved the highest yield and productivity for any system involving filamentous-fungal whole-cells. Following this, the ability to reuse the whole-cell biocatalysts for multiple reactions was explored via encapsulation of the filamentous fungal whole cells. Here it was found that encapsulation of the fungal cells in Ca-alginate beads enabled the biocatalysts to be reliably recycled for up to nine reaction cycles"--

Available in PDF, EPUB and Kindle. Book excerpt: This proceedings volume represents the culmination of nearly three years of planning, organizing and carrying out of a NATO Ad vanced Study Institute on Biomass Utilization. The effort was initi ated by Dr. Harry Sobel, then Editor of Biosources Digest, and a steering committee representing the many disciplines that this field brings together. . When the fiscal and logistical details of the original plan could not be worked out, the idea was temporarily suspended. In the spring of 1982, the Renewable Materials Institute of the State University of New York at the College of Environmental Science and Forestry in Syracuse, New York revived the plan. A number of modifications had to be made, including the venue which was changed from the U.S.A. to Portugal. Additional funding beyond the basic support provided by the Scientific Affairs Division of NATO had to be obtained. Ul timately there were supplementary grants from the Foundation for Microbiology and the Anne S. Richardson Fund to assist student participants. The New York State College of Forestry Foundation, Inc. provided major support through the Renewable Ma terials Institute. The ASI was held in Alcabideche, Portugal from September 26 to October 9, 1982. Eighty participants including fifteen principal lecturers were assembled at the Hotel Sintra Estoril for the program that was organized as a comprehensive course on biomass utilization. The main lectures were supplemented by relevant short papers offered by the participants.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Advances of Basic Science for Second Generation Bioethanol from Sugarcane written by Marcos S. Buckeridge and published by Springer. This book was released on 2017-03-10 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the basic science recently produced in Brazil for the improvement of sugarcane as a bioenergy crop and as a raw material for 2nd generation bioethanol production. It reports achievements that have been advancing the science of cell walls, enzymes, genetics, and sustainability related to sugarcane technologies and give continuity to the research reported in the “Routes to Cellulosic Ethanol”, from Springer. The Introduction (Chapter I) explains how the National Institute of Science and Technology of Bioethanol, founded in 2008 in Brazil, became part of the main international initiatives that started to search for forms to use biomass for bioethanol production in Brazil, US and Europe. Part I reports the advances in plant cell wall composition, structure and architecture, and physical characteristics of sugarcane biomass. These discoveries are opening the way to increased efficiency of pretreatments and hydrolysis, being therefore important information for 2nd generation processes as well as for biorefinery initiatives. Part II focuses on the discovery and characterization of hydrolases from microorganisms that could be used in industrial processes. Recent advances in the search for hydrolases using metagenomics is reported. A great number of genes and enzymes from microorganisms have been discovered, affording improvement of enzyme cocktails better adapted to sugarcane biomass. Part III reports two key issues in the process of 2G ethanol, pentose fermentation and sugarcane genetics. These are the discoveries of new yeast species capable of producing ethanol more efficiently from xylose and the advances made on the sugarcane genetics, a key issue to design varieties adapted to 2G ethanol production. Part IV approaches sustainability through two chapters, one discussing the sustainability of the sugarcane agricultural and environmental system and another discussing how national and mainly international policies of Brazil regarding 2G ethanol production affected the country’s strategies to establish itself as an international player in renewable energy area.
