Available in PDF, EPUB and Kindle. Book excerpt: This book provides a knowledge-based view to the dynamic capabilities in an organization. The author integrates two existing views on gaining competitive advantage: the Knowledge View which suggests that the capability of organizations to learn faster than competitors is the only source of competitiveness; and the Dynamic Capability View which speculates that a fi rm’s competitive advantage rests on it’s ability to adapt to changes in the business environment. Using the IT sector in India as a case study, this book provides and tests a new framework—Knowledge-Based Dynamic Capabilities—in the prediction of competitive advantage in organizations.
Download or read book Storage of Fungal Treated Lignocellulosic Biomass and Its Acceptance by Goats written by and published by . This book was released on 2019 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vast amounts of organic residues (including wheat straw) are produced as a result of agricultural activities. Because of a lignin content, many of these biomasses cannot be effectively used as feedstuffs. Selective white-rot fungi uniquely degrade lignin and, thereby, can increase the value of lignified biomasses as a feedstuff. A number of important issues need to be solves to allow for application of this biotechnology in practice. Among these are the stability of fungal treated biomass during long term storage, the compounds produced during fungal treatment and storage, and acceptance of fungal treated biomass by ruminant animals. The research reported in the present thesis showed that wheat straw treated by the fungi Ceriporiopsis subvermispora or Lentinula edodes could be anaerobically stored, with or without additives, at 20 °C up to 64 days with minor effect on its composition. Both fungi acidified the wheat straw by producing a number of organic acids and soluble sugars which accumulated during the fungal treatment. Accumulation of specific ceriporic acids were observed during the C. subvermispora treatment. No common mycotoxins were found to be produced in the two fungal cultures, indicating that the treated wheat straw was safe for animals to consume, at least from the perspective of the 34 analysed mycotoxins. Storing fungal treated wheat straw at different temperatures showed small but significant differences in hemicellulose and lignin content at higher temperatures, but did not affect fermentability in rumen fluid. A number of metabolites accumulated with increased storage temperatures and time. Preference studies with goats showed that the fungal treated wheat straw was well accepted as part of a grass silage and corn silage based ration. Storage of fungal treated wheat straw at elevated temperatures increased its palatability. By adding wheat bran before fungal treatment, a more rapid colonization by C. subvermispora, but not L. edodes, occurred but did not affect the extent of lignin degradation.

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.

Book excerpt: In the case of a natural or man-made global catastrophe such as an asteroid strike, supervolcano eruption, or nuclear winter, agricultural disruption in the aftermath of the disaster could have as large of a global human cost as the event itself. In this project, we attempted to find creative ways to address global food scarcity by exploring the use of a universally acquirable material: inedible lignocellulosic plant material. We tapped into the nutritional potential of a complex polysaccharide-rich plant substrate, shrub willow (Salix sp), using a pretreatment of two white-rot fungi strains, Pleurotus ostreatus and Lentinula edodes, in combination with an enzymatic hydrolysis treatment. We compared the changes in biochemical composition of our lignocellulosic substrate that occurred throughout the fungal incubation period to the nutritional value and yield of edible products obtained from enzymatic hydrolysis and from fungal fruiting bodies. In this Honors Thesis, we suggest a pretreatment strategy that can be used to maximize the transformation of woody biomass into a potential caloric source for emergency human consumption.
Download or read book Lignocellulose Conversion written by Vincenza Faraco and published by Springer Science & Business Media. This book was released on 2013-06-12 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Manganese Assisted Fungal Treatment of Lignocellulosic Biomass for Biofuels Production written by Xiao Fu and published by . This book was released on 2019 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation study explored the effect of manganese addition on fungal treatment for improving enzymatic hydrolysis of different lignocellulosic feedstocks. The main topics included investigating destruction of lignocellulose structures and changes in biomass compositions, revealing the mechanism of enhanced preferential delignification by Mn addition, and developing an effective Mn assisted fungal treatment (MAFT) for improving biomethane yield. First, the effects of Mn addition on treatment of wheat straw and poplar with Phanerochaete chrysosporium were investigated. After 28 d treatment, ~50% sugar yield was obtained from the treated wheat straw and poplar with Mn addition of 0.01 mM/g biomass, which was 4-8 folds increase over the biomass treated only with fungus. The increased sugar yield of the treated biomass resulted from the combined effects of selective lignin degradation, reduced cellulose consumption, and destruction of the biomass structure after Mn addition. The Mn-assisted treatment was further tested with another fungus, Ceriporiopsis subvermispora. Approximately 85% sugar yield was obtained. Analysis of the compositional and structural characteristics of the biomass indicated that the key factors that led to high sugar yield were the enhanced degradation of lignin and minimal cellulose consumption. The mechanism of delignification by Mn-assisted C. subvermispora was related to be an increased activity of manganese peroxidases (MnPs) that led to preferential degradation of S-lignin units via breakdown of Îø-O-4 ether linkages. Finally, the effective MAFT (C. subvermispora) was used to treat biomass for maximizing biomethane yield with reduced treatment times. MAFT effectively improved the biodegradability of wheat straw and corn stover up to ~97% after 14 d treatment. The corresponding methane yield was ~310 L/kg volatile solids (VS), which was 1.4-folds higher than that of the untreated samples. This study suggests a possible pretreatment method for producing sugar and biomethane from lignocellulose. It also addresses knowledge gaps pertaining to preferential delignification by fungus enhanced by Mn addition and improved digestibility of biomass.

Available in PDF, EPUB and Kindle. Book excerpt: Lignocellulosic wastes has been widely discussed as a promising natural chemical source and alternative feedstock for second-generation biofuels. However, there are still many technical and economic challenges facing its utilization. Lignin is one of the components of lignocellulosic biomass, and is the most rigid constituent and can be considered as a glue providing the cell wall with stiffness and the plant tissue with compressive strength. In addition, it provides resistance to chemical and physical damage. Resistance of lignocelluloses to hydrolysis is mainly from the protection of cellulose by lignin and cellulose binding to hemicellulose. The present book provides basic knowledge and recent research on different applications of biomass, focusing on the bioenergy and different pretreatment methods that overcome the aforementioned hurdles.
