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.

The rates of ethylene production per unit mass of Mucor hiemalis are highest at low specific growth rates. Thus this fungus probably produces more ethylene in the soil, where growth rates are low, than would have been predicted by laboratory batch culture, where growth rates are high. The rate of utilization of energyyielding substrate by Mucor hiemalisincreases logarithmically with growth rate...

A strain of a novel mucoralean fungus was isolated from a nest of the invasive paper wasp, Polistes dominulus. Phylogenetic analysis based on the internal transcribed spacer (ITS) regions and 5.8S rRNA gene sequences, along with physiological tests, revealed that this strain represents a novel species within the genus Mucor. The novel species also includes a representative that had previously b...

objective fungi produce many different carotenoids and some are attractive in medical and industrial sources. in this work the ability of mucor hiemalis (ptcc 5292) to produce carotenoids in media with different nitrogenous and carbon sources and incubation with white, yellow, blue and red lights (15w, 220v, e27) against dark-grown were studied. materials and method the microorganism cultivatio...

Knowledge on the factors that determine the composition of bacterial communities in the vicinity of roots (rhizosphere) is essential to understand plant-soil interactions. Plant species identity, plant growth stage and soil properties have been indicated as major determinants of rhizosphere bacterial community composition. Here we show that the presence of saprotrophic fungi can be an additiona...

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, ...
