Psychrophilic basidiomycete yeast, Glaciozyma antarctica strain PI12, was shown to be a protease-producer. Isolation of the PI12 protease gene from genomic and mRNA sequences allowed determination of 19 exons and 18 introns. Full-length cDNA of PI12 protease gene was amplified by rapid amplification of cDNA ends (RACE) strategy with an open reading frame (ORF) of 2892 bp, coded for 963 amino ac...

The infection of stored apples by the fungus Penicillium expansum causes the contamination of fruits and fruit-derived products with the mycotoxin patulin, which is a major issue in food safety. Fungal attack can be prevented by beneficial microorganisms, so-called biocontrol agents. Previous time-course thin layer chromatography analyses showed that the aerobic incubation of patulin with the...

This study investigated the fermentability of hemicellulosic hydrolysates obtained by intensified steam explosion pretreatment switchgrass (Panicum virgatum) and Eucalyptus globulus. Xylitol carotenoids were high-value molecules produced fermentation. The allowed to process a large amount biomass per unit time resulted in containing high sugars, among which, significant fraction was form oligom...

The presence of toxic compounds in lignocellulosic hydrolysates is one the main problems affecting efficiency hydrolysate-based fermentation processes. Understanding effects biomass-derived inhibitors on performance microbial strain essential to develop strategies able result an improved performance. In present study, efforts were done elucidate growth oleaginous yeast Rhodosporidium toruloides...

O biodiesel tem sido uma importante alternativa energética para a redução da emissão de gases poluentes, contudo, os óleos vegetais e gorduras animais utilizados como matérias-primas sua síntese possuem restrições que limitam o processo produtivo. Este trabalho trata-se revisão literatura sistemática discute possíveis aplicações reaproveitamento do glicerol bruto oriundo transesterificação óleo...

In the present study basidiomycetous yeast species were characterised from soil samples in different regions of Iran. Soil samples were collected from 5–15 cm depth, subsequently yeasts were isolated and purified. Yeast isolates were identified using D1/D2 domains of 26S rRNA and physiologic tests. The results of this study revealed a rich diversity amongst basidiomycetous yeast species in the ...
