This work evaluated sugarcane bagasse pretreatment with wood-decay fungi, producing varied patterns of biodegradation. The overall mass balance sugars released after and enzymatic hydrolysis indicated that a selective white-rot was necessary to provide glucose yields similar the ones observed from leading physico-chemical technologies. Ceriporiopsis subvermispora for lignin degradation in lignocellulosic material, preserved most glucan fraction, increased cellulose digestibility biotreated...
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 ability of white-rot fungi to degrade polysaccharides in lignified plant cell walls makes them a suitable reservoir for CAZyme prospects. However, date, CAZymes from these species are barely studied, which limits their use the set choices biomass conversion modern biorefineries. current work joined secretome studies two representative fungi, Phanerochaete chrysosporium and Trametes versicolor, with expression analysis cellobiohydrolase (CBH) genes, secretomes evaluate enzymatic simple...
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...
