In situ hydrogen, acetone, butanol, ethanol and microdiesel production by Clostridium acetobutylicum ATCC 824 from oleaginous fungal biomass

Production of butanol and polyhydroxyalkanoate from industrial waste byClostridium beijerinckiiASU10

“…While, from our previous studies, C beijerinckii ASU10 showed a considerable butanol production on potato peels containing 46 g L −1 , sugar (10.98 g L −1 ), corn starch soluble (9.6 g L −1 ), and cheese whey (3.37 g L −1 ) . As well as, the solvent production by C acetobutylicum ATCC 824 on potato peels (2.19 g L −1 ), corn starch soluble (4.76 g L −1 ), cheese whey (1.80 g L −1 ), and crude fungal biomass (2.19 g L −1 ) . Biobutanol production by anaerobic fermentation has a considerable application potential as a transportation fuel that characterized by higher‐energy content, octane values, and blending ability with gasoline/diesel liquid fuels without the need of vehicle motor modifications …”

“…Consequently, interest in biofuel production, which received a little attention following the industrial revolution development, has been restored . However, the main drawbacks of industrialization and recommercialization of the green chemicals are the lack of cost‐effectiveness because of the absence of cheap, available, and utilizable feedstock for the generation of high yields of hydrogen and acetone, butanol, and ethanol (ABE) . Solventogenic Clostridium is strictly anaerobic and has the ability to ferment various industrial wastes for the production of various renewable energy sources .…”

[8][9][10][11] Solventogenic Clostridium is strictly anaerobic and has the ability to ferment various industrial wastes [12][13][14][15] for the production of various renewable energy sources. 5,8,9 Among fermentative solventogenic Clostridium are Clostridium beijerinckii, Clostridium acetobutylicum, Clostridium saccharobutylicum, Clostridium saccharaoperbutylacetonicum, Clostridium pasteurianum, and Clostridium tyrobutyricum.…”

Avaliação do potencial do fungo filamentoso <i>Mucor circinelloides</i> como fonte de lipase e lipídios para a produção de biodiesel dentro do conceito de biorrefinaria

“…Além disso, lipases e catalisadores ácidos podem promover simultaneamente esterificação de ácidos graxos e transesterificação de triacilgliceróis, de modo que estes catalisadores são recomendados quando o teor de ácidos graxos no óleo é elevado (> 3% em massa), tal como no óleo microbiano (CARRERO et al, 2015;HASSAN et al, 2015;WU, 2007 Alternativamente, a produção de biodiesel pode ser processada diretamente a partir da biomassa dos microrganismos oleaginosos sem a prévia extração do lipídio SHI et al, 2011;VICENTE et al, 2009 …”
