Some 340 isolates belonging to Mucorales, obtained from rhizosphere of root knot nematode host plants in ChaharMahal & BakhtiariProvince, were studied during 2003-5. Fourteen new taxa, namely, Absidia spinosa, Actinomucor elegans, Cunninghamella echinulata var. echinulata, C. echinulata var. nodosa, C. echinulata var. verticillata, Mucor circinelloides f. circinelloides, M. circinelloides f. lu...

The occurrence of the iron-reducing phenomenon among some common fungi was studied. Results indicated that (i) the reduction of ferric iron to the ferrous state by fungi seems to be restricted to nitrate reductase-inducible strains such as Actinomucor repens, Alternaria tenuis, Fusarium oxysporum, and F. solani and (ii) the amount of dissolved ferrous iron may be reduced progressively by increa...

This study was undertaken to validate the use of microbial biotransformation systems for drug metabolism studies. Thymoxamine 1 was rapidly hydrolyzed to desacetylthymoxamine (DAT) 2 by numerous fungi. Other known animal metabolites, such as N-desmethyl-desacetylthymoxamine 3 and desacetylthymoxamine-O-sulfate 6, were produced from DAT by Mucor rouxii and Mortierella isabellina. DAT-N-oxide 5, ...
