2. 1. Filamentous Fungi as a Sustainable Ingredient for Fish Feed

   Author : Sajjad Karimi; José Teixeira; Högskolan i Borås; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; compound feed; edible filamentous fungi; essential amino acids; low-value substrates; polyunsaturated fatty acids; protein sources; submerged cultivation; thin stillage; Resource Recovery; Resursåtervinning;

   Abstract : Limited feed ingredients hinder aquaculture’s rapid growth. Current unsustainable fish feeding practices use ingredients like fishmeal and soybean meal, which could be directly consumed for as human food. This demands novel alternatives for fish nutrition. READ MORE

4. 2. Integration of filamentous fungi in ethanol dry-mill biorefinery

   Author : Jorge Ferreira; Högskolan i Borås; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; airlift bioreactors; ascomycetes; biomass; bubble column; ethanol; feed; Neurospora intermedia; thin stillage; zygomycetes; Resursåtervinning; Resource Recovery;

   Abstract : The industrial production of bioethanol as a replacement to gasoline is well-established worldwide, using starch- or sugar-rich substrates. Additionally, the bioethanol plants produce animal feeds derived from fermentation leftovers. The biorefinery character of bioethanol plants can be enhanced via process diversification. READ MORE

5. 3. Biogas production from thin stillage : exploring the microbial response to sulphate and ammonia

   Author : Jan Moestedt; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The biogas plant in Norrköping (Tekniska verken i Linköping AB, publ.), Sweden, operates with thin stillage, a residue from bio-ethanol fermentation, as the main feedstock. Thin stillage is energy-rich due to its high protein content, but due to its high nitrogen and sulphate content is a somewhat complicated feedstock. READ MORE

6. 4. Integration of first and second generation bioethanol processes using edible filamentous fungus Neurospora intermedia

   Author : Ramkumar B Nair; Högskolan i Borås; []
   Keywords : First- and second-generation bioethanol; Integration; Neurospora intermedia; Edible filamentous fungi; Wheat straw; Wheat bran; Whole stillage fiber; Biochemistry; Biokemi;

   Abstract : Establishing a commercial, lignocellulose-based, second-generation ethanol process has received several decades of attention by both researchers and industry. However, a fully economically viable process still remains a long-term goal. READ MORE

7. 5. Development of Simultaneous Saccharification and Fermentation for Production of Ethanol from Softwood

   Author : Malek Alkasrawi; Centrum för analys och syntes; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; Kemiteknik och kemisk teknologi; spruce; softwood; fermentation; cultivation; Tween-20; SSF; recirculation; Ethanol production; process streams;

   Abstract : This thesis deals with the development of simultaneous saccharification and fermentation (SSF) in order to improve the economy of the softwood-to-ethanol process. The effect of process stream recirculation on ethanol production from steam-pretreated softwood based on SSF was investigated for two process cases. READ MORE
