Proteases possuem um papel fundamental na economia, estando presentes em diversos setores industriais. Dentre os fungos conhecidos por produzir proteases, destaca-se o gênero Aspergillus. Desta forma, objetivo deste trabalho foi proteases a partir de fermentação estado sólido Aspergillus ochraceus, purificar, caracterizar e avaliar seu potencial produção enzima colagenolítica fibrinolítica. Par...

OBJECTIVE To isolate and characterize the bioactive secondary metabolites from Aspergillus ochraceus (A. ochraceus) MP2 fungi. METHODS The anti bacterial activity of marine sponge derived fungi A. ochraceus MP2 was thoroughly investigated against antagonistic human pathogens. The optimum inhibitory concentration of the fungi in the elite solvent was also determined. The promising extracts tha...

The effect of dextranases (EC 3.2.1.11) from the oral isolates Actinomyces israelii and Bacteroides ochraceus on water-insoluble glucan production by the Streptococcus mutans dextransucrase (EC 2.4.1.5) and sucrose-dependent adherence to smooth glass surfaces by S. mutans was studied. Collection on membrane filters of water-insoluble polysaccharides synthesized from radioactive sucrose was used...

A case report describing Capnocytophaga ochracea (Bacteroides ochraceus) septicemia in a 21-year-old male patient receiving chemotherapy for acute lymphocytic leukemia is presented. The unusual features of this organism are discussed together with a review of the literature.

Isolates of Aspergillus chevalieri, A. flavus, A. ochraceus, A. repens, and Penicillium funiculosum and complexes of P. citrinum-P. implicatum isolated from moldy pecan meats were toxic to chicks.

Ochratoxin A is a mycotoxin present in several food products for which levels should be reduced. Chemical, physical, and biological methods have been proposed for the detoxification of mycotoxins, biological methods being the more promising ones. In this report, filamentous fungi isolated from Portuguese grapes were assessed for ochratoxin A degradation capabilities. It was observed that 51 of ...

Background: In Benin Republic, the conservation of fermented fishes for a long time is difficult due to the contamination of fungi, which lead to its rapid degradation. This experiment was conducted to evaluate the effect of Cymbopogon citratus Essential Oil (EO) against Aspergillus species isolated from fermented fish samples. Methods: Gas chromatography-mass spectrometry was used to determin...
