RESUMO

Thirty-eight taxa of Zygomycetes distributed in 15 genera were recorded from tapir (Tapirus terrestris), camel (Camelus bactrianus), horse (Equus caballus), deer (Cervus elaphus), agouti (Dasyprocta aguti), donkey (Equus asinus), llama (Llama glama) and waterbuck (Kobus ellipsiprymnus) dung collected at the Reserva Ecológica de Dois Irmãos located in Recife, State of Pernambuco, Northeast Brazil. The samples were collected on a monthly basis from June 2005 to May 2006, taken to the laboratory and incubated in moist chambers. Higher number of taxa was observed in the excrements of tapir, followed by deer and donkey. The highest number of species was detected for Mucor, followed by Pilobolus. Statistical analyses showed significant differences in richness of Zygomycetes taxa between the herbivore dung types. Differences of species composition, however, were weak. Seasonality influenced the Zygomycetes species composition but not its richness. Variations in taxa composition between ruminants and non-ruminants dung were non significant.

RESUMO

Mucoraleswere 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.

Mucorales foram isolados da farinha de milho, fubá e flocos de milho pré-cozidos pelos métodos de plaqueamento em superfície e em profundidade. Rhizopus oryzae, Circinella muscae, Mucor subtilissimus,Mucor hiemalis f. hiemalis, Syncephalastrum racemosum, Rhizopus microsporus var. chinensis e Absidia cylindrospora exibiram atividade proteásica.
