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.

Polyphenolic content and bactericidal effect of Mexican and .

In this study, total phenolics, total flavonoids, hesperidin and ascorbic acid contents in bagasse, juice and seed of mexican sweet lime () and mandarine () were determined at two commercial maturity stages (maturation index), as well as their bactericidal effect on and . The results showed that bagasses had the highest total phenolics, total flavonoids, and hesperidin content for both, , and ; highest ascorbic acid contents were found in juice (3.36 ± 0.
