Book excerpt: The design of new food products and increased agricultural activities have produced a diversity of waste streams or byproducts that contain a high load of organic matter. Recently, oleaginous microorganisms (>20% lipid content) have emerged as a tool for improved resource efficiency by converting agricultural waste streams to valuable food and fuel ingredients. Thus, the overall objective of this project was to optimize the use of a filamentous fungus (Mucor circinelloides) that is able to convert the organic matter in food by-products into an oil-rich biomass. Whey permeate, a secondary dairy by-product arising from the production of whey protein concentrates, was investigated as a model source for this fungus cultivation. Through the use of response surface methodology, we were able to optimize the cultivation conditions (pH, temperature) for improved biomass production and lipid content at shake-flask. The fatty acid profile indicated the suitability of M. circinelloides oil as a potential feedstock for biofuel production and nutraceutical applications. The fermentation of M. circinelloides was then successfully scaled-up to a stirred tank bioreactor. Since oxygen transfer is a key variable in aerobic reactor fermentations, the process was further optimized in terms of agitation speed, and aeration rate. Cultivation in a bioreactor was found to not only improve fungal growth, but also lipid content and lipid yield compared to that of shake-flask. The end result of this project was a scaled-up optimized fermentation process that will increase the M. circinelloides biomass yield and composition as raw material for food, feed, and fuel. This signifies a starting point for further studies aimed at assessing the development of a fully functioning fungi-to-food/fuel system on an industrial scale for several agricultural streams. At the same time, this pathway would safely treat effluent streams that are currently problematic for the industry to dispose of in an environmentally friendly manner.

Book Synopsis Sustainable Bioconversion of Waste to Value Added Products by : Inamuddin

Download or read book Sustainable Bioconversion of Waste to Value Added Products written by Inamuddin. This book was released on 2021-04-20. Available in PDF, EPUB and Kindle. Book excerpt: This edited book discusses various processes of feedstocks bioconversion such as bioconversion of food waste, human manure, industrial waste, beverage waste, kitchen waste, organic waste, fruit and vegetable, poultry waste, solid waste, agro-industrial waste, cow dung, steroid, lignocellulosic residue, biomass, natural gas etc. Nowadays, the industrial revolution and urbanization have made human life comfortable. However, this requires excess usage of natural resources starting from food and food products, to energy resources, materials as well as chemicals. The excess use of natural resources for human comfort is expected to high fuel prices, decline natural resources as well as cause a huge hike in the cost of raw materials. These factors are pushing researchers to grow environmentally friendly processes and techniques based on inexpensive and sustainable feedstock to accomplish such worldwide targets. Bioconversion, otherwise called biotransformation, is the change of natural materials, for example, plant or animal waste, into usable items or energy sources by microorganisms. Bioconversion is an environmentally friendly benevolent choice to supplant the well-established chemical procedures utilized these days for the production of chemicals and fuels. A variety of alternatives advancements are being considered and are directly accessible to acquire diverse valuable end-products through bioprocesses. This book discusses in detail the process and techniques of bioconversion by focusing on the organic feedstock of animal and plant origin. It brings solutions to the bioconversion of various feedstock into value-added products.

Book Synopsis Utilisation of Bioactive Compounds from Agricultural and Food Production Waste by : Quan V. Vuong

Download or read book Utilisation of Bioactive Compounds from Agricultural and Food Production Waste written by Quan V. Vuong. This book was released on 2017-09-07. Available in PDF, EPUB and Kindle. Book excerpt: The large quantity of waste generated from agricultural and food production remains a great challenge and an opportunity for the food industry. As there are numerous risks associated with waste for humans, animals and the environment, billions of dollars are spent on the treatment of agricultural and food waste. Therefore, the utilisation of bioactive compounds isolated from waste not only could reduce the risks and the costs for treatment of waste, but also could potentially add more value for agricultural and food production. This book provides comprehensive information related to extraction and isolation of bioactive compounds from agricultural and food production waste for utilisation in the food, cosmetic and pharmaceutical industries. The topics range from an overview on challenges and opportunities related to agricultural and food waste, the bioactive compounds in the waste, the techniques used to analyse, extract and isolate these compounds to several specific examples for potential utilisation of waste from agricultural and food industry. This book also further discusses the potential of bioactives isolated from agricultural and food waste being re-utilised in the food, cosmetic and pharmaceutical industries. It is intended for students, academics, researchers and professionals who are interested in or associated with agricultural and food waste.

Book Synopsis Biotechnology of Filamentous Fungi by : David B. Finkelstein

Download or read book Biotechnology of Filamentous Fungi written by David B. Finkelstein. This book was released on 2013-10-22. Available in PDF, EPUB and Kindle. Book excerpt: Biotechnology of Filamentous Fungi: Technology and Products provides a comprehensive discussion of the molecular biology, genetics, and biochemistry of filamentous fungi. It also deals with general principles of biochemical engineering such as process design and scaleup. The book's main emphasis, however, is on the commercial significance of filamentous fungi. The book highlights the unique aspects of filamentous fungi along with those aspects common to most microorganisms studied in industries that use biotechnology. Filamentous fungi can generate a wide range of industrial products including primary metabolites such as organic acids, secondary metabolites such as ß-lactam antibiotics, nonantibiotic drugs, and enzymes for use in food production. Whole organisms such as mushrooms can be used as well as organisms used as insecticides and herbicides. Filamentous fungi also qualify as potential hosts for the secretion of certain heterogeneous proteins such as mammalian proteins. However, not all things related to fungi are beneficial. Mycotoxins products by fungi can be lethal to humans; there is also a need to develop antifungal agents to destroy fungi that can kill animals and plants. These topics are important aspects of the biotechnology of filamentous fungi and are dealt with in this text.
