Linolenic Acid Plus Ethanol Exacerbates Cell Death in by Promoting Lipid Peroxidation, Cardiolipin Loss, and Necrosis.

Polyunsaturated fatty acids (PUFA) hypersensitize yeast to oxidative stress. Ethanol accumulation during fermentation is another factor that induces oxidative stress via mitochondrial dysfunction and ROS overproduction. Since this microorganism has raised growing interest as a PUFA factory, we have studied if the combination of PUFA plus ethanol enhances yeast death.

Optimization of production of xylanases with low cellulases in Fusarium solani by means of a solid state fermentation using statistical experimental design.

Demand for fungal xylanases in industrial biotechnological processes shows a clear increase worldwide, so there is an interest in adjusting the conditions of microbial xylanases production. In this study, the ability of the fungus Fusarium solani to produce extracellular xylanases with low cellulolytic activity was optimized by Box Wilson design. The best culture conditions were determined to obtain a crude enzyme preparation with significant xylanolytic activity and little cellulolytic activity.
