Microbial conversion of milbemycins: hydroxylation of milbemycin A4 and related compounds by Cunninghamella echinulata ATCC 9244.
Many strains of zygomycetes and actinomycetes were found to convert milbemycin A4 (1a) to 13 beta-hydroxymilbemycin A4 (1b). Among these strains, Cunninghamella echinulata ATCC 9244 had the most efficient 13 beta-hydroxylation ability on milbemycins. In the conversion of milbemycin A3 (2a), 29-hydroxymilbemycin A4 (4a), and 30-hydroxymilbemycin A4 (5a) with this strain, only 13 beta-hydroxylate...
متن کاملMetabolism of (+/-)-N-(n-propyl) amphetamine by Cunninghamella echinulata.
(+/-)-N-(n-propyl) amphetamine (I), a secondary amine, was readily metabolized by Cumminghamella echinulata. The products included known C- and N-oxygenated mammalian metabolites as well as N-acetylamphetamine and were identified by gas chromatography and mass spectrometry.
متن کاملIsolation and Characterization of Three Unrecorded Zygomycete Fungi in Korea: Cunninghamella bertholletiae, Cunninghamella echinulata, and Cunninghamella elegans
In a survey of undiscovered taxa in Korea, three zygomycete fungal strains-EML-W31, EML-HGD1-1, and EML-RUS1-1-were isolated from freshwater, grasshopper fecal, and soil samples in Korea. On the basis of the morphological characteristics and phylogenetic analysis of internal transcribed spacer and 28S rDNA, the isolates of EML-W31, EML-HGD1-1, and EML-RUS1-1 were confirmed to be Cunninghamella ...
متن کاملCarbazole hydroxylation by the filamentous fungi of the Cunninghamella species
Nitrogen heterocyclic compounds, especially carbazole, quinolone, and pyridine are common types of environmental pollutants. Carbazole has a toxic influence on living organisms, and the knowledge of its persistence and bioconversion in ecosystems is still not complete. There is an increasing interest in detoxification of hazardous xenobiotics by microorganisms. In this study, the ability of thr...
متن کاملMicrobial transformation of sesquiterpene lactones by the fungi cunninghamella echinulata and rhizopus oryzae
Incubations of the fungi Cunninghamella echinulata and Rhizopus oryzae with the sesquiterpene lactones (+)-costunolide (1), (+)-cnicin (2), (+)-salonitenolide (3), (-)-dehydrocostuslactone (4), (-)-lychnopholide (5), and (-)-eremantholide C (6) were perfomed. Incubation of 1 with C. echinulata afforded Delta11(13)-dihydrogenation and Delta1(10)-epoxidation products (7-10). C. echinulata also hy...
