Microbial hydroxylation of 1,4-cineole.
Microorganisms were examined for their potential to hydroxylate the oxygenated monoterpene 1,4-cineole. Using gas chromatography and thin-layer chromatography, screening experiments revealed that hydroxylation at position 2 was the most commonly observed microbial transformation reaction. In most microorganisms, the predominant alcohol metabolite was the 2-endo-alcohol isomer. Preparative-scale...
متن کاملHydroxylation of 1,8-cineole by Mucor ramannianus and Aspergillus niger
The monoterpenoid 1,8-cineole is obtained from the leaves of Eucalyptus globulus and it has important biological activities. It is a cheap natural substrate because it is a by-product of the Eucalyptus cultivation for wood and pulp production. In this study, it was evaluated the potential of three filamentous fungi in the biotransformation of 1,8-cineole. The study was divided in two steps: fir...
متن کاملMicrobial hydroxylation of 16α, 17α-epoxyprogesterone by Penicillium decumbens
Microbial transformation has been successfully applied in the production of steroid intermediates with therapeutic use and commercial value in pharmaceutical industry due to its high regio- and stereo-selectivity. As such, it is still important to screen microbial strains with novel activity or more efficient abilities in the development of the commercial steroid industry. Biotransformation of ...

متن کاملMicrobial Hydroxylation of Indole Alkaloids.
The hydroxylation of the indole-type alkaloids, yohimbine, alpha-yohimbine, beta-yohimbine, and corynanthine, was achieved with several genera of higher fungi and species of Streptomyces. Microorganisms were found which monohydroxylated these compounds in three different positions. The site of hydroxylation was strain-specific for two strains of Cunninghamella echinulata and C. bainieri.
