Methods to Increase Phenothiazine Conversion in Beauveria bassiana

Felipe Nicolau & Tonya L. Peeples · Journal of Advances in Biology & Biotechnology · 2015

Aims: The degradation of phenothiazine with the filamentous fungus Beauveria bassiana was studied under different fermentation conditions. The objective was to demonstrate methods to increase substrate conversion in wild type B. bassiana using phenothiazine as a screening substra...

N-alkane Solvent-enhanced Biotransformation of Steroid DHEA by Beauveria bassiana as Biocatalyst

Richard Gonzalez, Felipe Nicolau & Tonya L. Peeples · Journal of Advances in Biology & Biotechnology · 2014

Aims: The hydroxylation capacity of Beauveria bassiana was enhanced with n-alkane solvents, resulting in a selective and eco-friendly scheme for the synthesis of steroids. A biocatalytic system was engineered to augment the 11α-hydroxylation of dehydroepiandrosterone (DHEA) to va...
