Control of chemoselectivity of microbial reaction with resin adsorbent: enhancement of Baeyer–Villiger oxidation over reduction

Prevalence and specificity of Baeyer-Villiger monooxygenases in fungi

Out of 107 fungal strains belonging to three phyla (Ascomycota, Basidiomycota and Zygomycota) and 46 genera, 86 exhibited Baeyer-Villiger monooxygenase (BVMO) activity against racemic bicyclo[3.2.0]heptenone. The strains were classified into three "profiles" based on regio- and enantioselectivity. Statistical analyses of our results, extended by literature data, showed that these profiles could be related to the taxonomic classification of the strains, and suggest that the BVMOs from the Zygomycota phylum may be different in their primary structures from established ones.

Relationship between interfacial hydrophobicity and hydroxylation activity of fungal cells located on an organic-aqueous interface

In a liquid-liquid interface bioreactor, fungal cells locate in a hydrophilic polyacrylonitrile microsphere layer on an aqueous-organic interface. In this article, effects of hydrophobicity of the interface on n-decane hydroxylation activity of Monilliera sp. NAP 00702 was examined. (-)-4-Decanol production was significantly enhanced to 132% by addition of polytetrafluoroethylene.
