Partial Purification and Properties of Cellulase-Free Alkaline Xylanase Produced by Rhizopus stolonifer in Solid- State Fermentation
Rhizopus stolonifer was cultivated in wheat bran to produce a cellulase-free alkaline xylanase. The purified enzyme obtained after molecular exclusion chromatography in Sephacryl S-200 HR showed optimum temperature as 45o C and hydrolysis pHs optima as pH 6.0 and 9.0. Xylanase presented higher Vmax at pH 9.0 (0.87 μmol/mg protein) than at pH 6.0 and minor Km at pH 6.0 (7.42 mg/mL) than at pH 9.0.
متن کاملMicrobial hydroxylation of sclareol by Rhizopus stolonifer.
Incubation of sclareol with Rhizopus stolonifer affords in high yield a mixture of triols with 18-hydroxy-sclareol as the main component.
متن کاملRhizopus Soft Rot on Pear (Pyrus serotina) Caused by Rhizopus stolonifer in Korea
Rhizopus soft rot caused by Rhizopus stolonifer occurred on pears (Pyrus serotina) in the Jinju City Agricultural Products Wholesale Market in Korea from 2004 to 2005. The infection usually started from wounds due to cracking at harvest time. The lesions started as water-soaked, rapidly softened, then gradually expanded. The mycelia grew vigorously on the surface of the fruits and formed stolon...
متن کاملMicrobial Transformations of (+)-Isomenthol by Fusarium lini and Rhizopus stolonifer.
Microbial transformation of (+)-isomenthol (1) by various strains of fungi was investigated. Fusarium lini has successfully converted compound 1 into a new metabolite, 5α-hydroxyisomenthol (2), and a known metabolite, 1α-hydroxyisomenthol (3), whereas incubation with Rhizopus stolonifer only yielded metabolite 3. The transformed metabolites were structurally characterized on the basis of their ...
متن کاملCellobiose Dehydrogenase Production by the Genus Cladosporium
Cellobiose dehydrogenase (CDH EC.1.1.5.1) is an extracellular enzyme that mainly produced by wood-degrading fungi. It oxidizes cellobiose to cellobionolactone using a wide spectrum of electron acceptors. The key roles of CDH in growth, metabolism, and some other important cellular processes such as cellulose degradation in fungi have been noted. Since the demands for finding new sources of CDH ...
