Bio-Hydrogen Production from Cheese Whey by Dark Fermentation
This paper focuses on the production of bio-hydrogen by dark fermentation of de-proteinized (by membrane ultra-filtration) cheese whey, an abundant waste stream of the food industry. This waste stream contains mainly lactose, which was also used as reference substrate in bio-hydrogen production tests. Those tests were conducted in batch by using a thermally treated anaerobic sludge as inoculum ...
متن کاملDark Hydrogen Fermentation From Paper Mill Effluent (PME): The influence of Substrate Concentration and Hydrolysis
Paper mill effluent (PME) was used as an organic feedstock for production of biohydrogen via dark fermentation using heat-shock pretreated anaerobic sludge under mesophilic conditions. The influence of substrate concentration (5, 10 and 15 g-COD/L) and the initial pH (5 and 7) on the efficiency of dark hydrogen fermentation from PME were investigated. The highest hydrogen yield of 55.4 mL/g-COD...
متن کاملAlcoholic Fermentation of d-Xylose by Yeasts.
Type strains of 200 species of yeasts able to ferment glucose and grow on xylose were screened for fermentation of d-xylose. In most of the strains tested, ethanol production was negligible. Nineteen were found to produce between 0.1 and 1.0 g of ethanol per liter. Strains of the following species produce more than 1 g of ethanol per liter in the fermentation test with 2% xylose: Brettanomyces ...
متن کاملComparative Analyses of Homocitrate Synthase Genes of Ascomycetous Yeasts
Most ascomycetous yeasts have 2 homocitrate synthases (HCSs). Among the fungal lysine biosynthesis-related genes, only the HCS gene was duplicated in the course of evolution. It was recently reported that HCS of Saccharomyces cerevisiae has an additional function in nuclear activities involving chromatin regulation related to DNA damage repair, which is not related to lysine biosynthesis. Thus,...
متن کاملAntifungal Susceptibility Testing of Ascomycetous Yeasts Isolated from Animals.
Recent studies suggest that antifungal resistance in yeast isolates of veterinary origin may be an underdiagnosed threat. We tested a collection of 92 ascomycetous yeast isolates that were obtained in Spain from birds, mammals and insects for antifungal susceptibility. MICs to amphotericin B and azoles were low, and no resistant isolates were detected. Despite these results, and given the poten...
