Incubation of sclareol with Rhizopus stolonifer affords in high yield a mixture of triols with 18-hydroxy-sclareol as the main component.

O objetivo foi avaliar a capacidade das espécies fúngicas Aspergillus oryzae e Rhizopus oryzae em degradar desoxinivalenol (DON) em fermentação submersa. O meio submerso utilizado foi água destilada estéril contaminada com 1mg mL DON, inoculado com 4 × 10 esporos mL das espécies fúngicas. A amostragem foi realizada a cada 48 h até 240 h de processo, determinando a massa residual de DON, percent...

The use of dry mycelium of Rhizopus oryzae as biocatalyst for ester production in organic solvent has been studied. Mycelia with notable carboxylesterase activity were produced when different Tweens (20, 40, 60 and 80) were employed as main carbon source for the growth. Dry mycelium of four strains of Rhizopus oryzae proved effective for efficiently catalysing the synthesis of different flavour...

mucormycosis is an invasive fungal infection caused by filamentous fungi of the mucoraceae family. the genera most commonly responsible are mucor or rhizopus. the disease occurs mostly in association with diabetic ketoacidosis. mucormycosis has an extremely high death rate even when aggressive surgery is done. death rates range from 25-85% depending on the body area involved.a case of rhinocere...

this study represents an unusual case of mucormycosis localized in nasal cavity of a german shepherd dog. the patient was a 1-year-old male guard dog with unilateral nasal epistaxis, mucopurulent nasal discharge, sneezing and nose pawing. the dog had a history of head trauma about 2 months before admission, which was associated with mild self-limited epistaxis. initial nasal rhinoscopy showed s...

Aspergillus oryzae, Penicillium citrinum and Rhizopus stolonifer isolated from Taif soil, Saudi Arabia could survive in a liquid medium containing up to 500 !lglml Zn. Aspergillus oryzae and Penicillium citrinum were more tolerant to zinc toxicity than Rhizopus stolonifer. The resistance and accumulation of zinc in the tested fungi were discussed according to tolerance index and zinc uptake in ...

To date, expression of the lipase from Rhizopus oryzae (ROL) in Escherichia coli always led to the formation of inclusion bodies and inactive protein. However, the production of active ROL and its precursor ProROL in soluble form was achieved when E. coli Origami(DE3) and pET-11d were used as expression systems.

The present investigation deals with the kinetics of submerged extracellular lipases fermentation by both wild and mutant strains of Rhizopus oligosporus var.microsporus in a laboratory scale stirred fermentor. Other parameters studied were inoculum size, pH, agitation and rate of aeration. It was found that the growth and lipases production was increased gradually and reached its maximum 9.07±...

Soft rot in apple caused by Rhizopus oryzae was found for the first time in Korea. A detailed description of the specimen is given along with its internal transcribed spacer rDNA sequence. The fungus was identified as Rhizopus oryzae based on the mycological characteristics, molecular data, and pathogenicity testing.

paddy straw is one of the most abundant agricultural by-products in tamil nadu, india. itcontains high amounts of cellulose and lignin. the fungal strains were isolated from naturally decomposingsites of paddy straw. eight fungal strains were isolated and later these eight fungi were used for finding outtheir potential for the degradation of lignin and cellulose content of paddy straw. among ei...
