Myxothiazol, a new antibiotic from the myxobacterium Myxococcus fulvus, inhibited the growth of many yeasts and fungi at concentrations between 0.01 and 3 micrograms/ml. It was generally inactive against bacteria. The inhibitory effect was cytostatic. With Candida albicans, Saccharomyces cerevisiae, and Mucor hiemalis, the growth inhibition was neutralized by glucose. Soon after being added to ...

Zygomycosis is an opportunistic fungal infection with a high mortality rate. It is known to cause invasive disease in immunocompromised hosts but it may produce only cutaneous/ subcutaneous infections in immunocompetent hosts. Treatment is difficult due to its fulminant course and lack of effective anti-fungal drugs. Here, we report a rare case of subcutaneous zygomycosis caused by Mucor hiemal...

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...

Seven new polyketides, for which the trivial names hyafurones A1-B (1-3), hyapyrrolines A (4) and B (5), and hyapyrones A (6) and B (7) are proposed, were isolated from the fermentation broth of the myxobacteria Hyalangium minutum, strains NOCB-2(T) and Hym-3. Their structures were elucidated from NMR and HRESIMS data, and their geometric configuration was assigned based on NOE and vicinal (1)H...
