Production of cellulosic ethanol from lignocellulosic biomass leads to the generation a hemicellulosic hydrolysate during feedstock pretreatment. This is rich in sugars, but also contains inhibitory compounds (mainly acetic acid and phenolic compounds) concentrations that may be toxic microbial growth. Currently, this side-stream production process processed as waste, due lack feasible alternat...

BACKGROUND Red yeast species in the Rhodotorula/Rhodosporidium genus are outstanding producers of triacylglyceride and cell biomass. Metabolic engineering is expected to further enhance the productivity and versatility of these hosts for the production of biobased chemicals and fuels. Promoters with strong activity during oil-accumulation stage are critical tools for metabolic engineering of th...

BACKGROUND Industrial biotechnology that is able to provide environmentally friendly bio-based products has attracted more attention in replacing petroleum-based industries. Currently, most of the carbon sources used for fermentation-based bioprocesses are obtained from agricultural commodities that are used as foodstuff for human beings. Lignocellulose-derived sugars as the non-food, green, an...

Twelve yeasts isolated from lakes of Northwestern Patagonia, Argentina, belonging to eight genera (Sporobolomyces, Sporidiobolus, Rhodotorula, Rhodosporidium, Cystofilobasidium, Cryptococcus, Torulaspora, and Candida) were analysed for their ability to produce photoprotective compounds. For this purpose, three laboratory experiments were performed to study the effect of photosynthetically activ...

In this study, we employed microwave-acid pretreatment for water hyacinth (WH) to obtain liquid hydrolysate that contains sugars derived from holocellulosic components of biomass further oleaginous yeast fermentation. order remove the inhibitors such as furans after acid treatment, detoxification was done and compared efficiency step with non-detoxified towards capability Rhodosporidium toruloi...

BACKGROUND Microbial lipids are a potential source of bio- or renewable diesel and the red yeast Rhodosporidium toruloides is interesting not only because it can accumulate over 50% of its dry biomass as lipid, but also because it utilises both five and six carbon carbohydrates, which are present in plant biomass hydrolysates. METHODS R. toruloides was grown in batch and fed-batch cultures in...
