The production of ethanol by the new yeast Spathaspora arborariae using rice hull hydrolysate (RHH) as substrate, either alone or in co-cultures with Saccharomyces cerevisiae is presented. Cultivations were also carried out synthetic medium to gather physiological information on these systems, especially concerning their ability grow and produce presence acetic acid, furfural, hydroxymethylfurfural, which are toxic compounds usually present lignocellulosic hydrolysates. S. was able...
The aims of this work were to obtain, by evolutionary engineering, an industrial strain Saccharomyces cerevisiae tolerant high concentrations HMF and determine the expression levels genes previously described as responsible for tolerance. Cells grown under anaerobic oxygen limited conditions, in presence glucose or sucrose carbon sources. P6H9 presented ADH7 ARI1 HMF. This also showed higher ethanol productivity, biomass formation alcohol dehydrogenase activity comparing sensitive strains....
The objective of this work was to isolate bacteria from soil historically exposed tebuconazole and evaluate the biodegradation fungicide by them. Tebuconazole is a commonly used systemic triazol group, which inhibits sterol C-14 α -demethylation 24-methylenedihydrolanosterol, precursor ergosterol, cell membrane component in fungi. Microorganisms were isolated different methods sampling screening degrading performed bioreactors cultivations, with some isolates showing ability degrade up 42.76...
The aims of this work were to improve cell tolerance towards high concentrations furfural and 5-hydroxymethylfurfural (HMF) an osmotolerant strain Wickerhamomyces anomalus by means evolutionary engineering, determine its ethanol production under stress conditions. Cells grown in the presence furfural, HMF, either isolated or combination, osmotic pressure most toxic condition for parental was combination both furans, which it unable grow produce ethanol. However, tolerant adapted achieved a...
