Expression of a periplasmic β-glucosidase from Yarrowia lipolytica allows efficient cellobiose-xylose co-fermentation by industrial xylose-fermenting Saccharomyces cerevisiae strains.

This study aimed to compare the effects of cellobiose hydrolysis, whether occurring inside or outside the cell, on the ability of Saccharomyces cerevisiae strains to ferment this sugar and then apply the most effective strategy to industrial S. cerevisiae strains. Firstly, two recombinant laboratory S.

Combined Therapeutic Strategies Based on the Inhibition of Non-Oncogene Addiction to Improve Tumor Response in EGFR- and KRAS-Mutant Non-Small-Cell Lung Cancer.

Background: Oncogene-driven NSCLC is usually treated with targeted therapies using tyrosine kinase inhibitors (TKIs) to inhibit oncogene downstream signaling pathways, affecting tumor survival and proliferation. EGFR- and KRAS-mutant NSCLCs are the most represented subtypes, and they are treated in clinical practice with oncogene-targeting drugs in the first and second line, respectively. Unfortunately, the development of oncogene-independent resistant clones limits TKI efficacy.

f.a., sp. nov. and f.a., sp. nov., two yeast species isolated from mushrooms and associated insects in a Brazilian Amazonian rainforest biome.

Thirty yeast isolates belonging to the genera and were isolated from mushrooms and associated drosophilids collected in a Brazilian Amazonian rainforest biome. Analyses of the sequences of the intergenic spacer region and the D1/D2 domains of the large subunit rRNA gene showed that these isolates represent two distinct species. The first, represented by ten isolates, is phylogenetically related to and based on the sequences of the D1/D2 domains.
