Microbial transformation of the tetrazolinone herbicide F5231 was accomplished with the filamentous fungus Absidia pseudocylindrospora Hesseltine et Ellis (ATCC 24169). The fungus converted the herbicide to six metabolites which were identified spectrally by mass, infrared, and nuclear magnetic resonance spectroscopy.

such a galactosyl transfer reaction as well as the decomposition of raffinose in beet sugar production, they may also produce galactooligosaccharides. Mitutomi and OhtakaraX) reported the isolation and identification of six main oligosaccharides produced from raffinose by the action of the a-galactosidase from Pycnoporus cinnabarinus. In our preliminary experiments, however, the a-galactosidase...

Mucorales were isolated from maize flour, corn meal and cooked cornflakes using surface and depth plate methods. Rhizopus oryzae, Circinella muscae, Mucor subtilissimus, Mucor hiemalis f. hiemalis, Syncephalastrum racemosum, Rhizopus microsporus var. chinensis and Absidia cylindrospora showed protease activity.

Fungi belonging to class Zygomycetes become pathogenic in certain predisposing conditions; principally diabetes mellitus, immunosuppression, trauma or burns. We report a case of a 31-year-old man with acute promyelocytic leukemia who developed infection of the sino-oral cavity, due to Absidia corymbifera during a neutropenic phase following induction chemotherapy. A provisional diagnosis of zyg...

Posaconazole and itraconazole were more potent inhibitors of ergosterol synthesis, in both intact cells and cell extracts from Absidia corymbifera and Rhizopus oryzae, than voriconazole and fluconazole. Similarly, expression of CYP51 from R. oryzae in Saccharomyces cerevisiae significantly increased resistance to fluconazole and voriconazole but not to posaconazole and itraconazole.
