Extracellular β-d-xylosidase of Sclerotium rolfsii
Enzyme and Microbial Technology, 1985Abstract Culture conditions are described for the production of extracellular β- d -xylosidase (xylobiase, exo-1,4-β- d -xylosidase, 1,4-β- d -xylan xylohydrolase, EC 3.2.1.37) in shake flasks by Sclerotium rolfsii. At the 1% cellulose level, a maximum activity of 0.82 U ml −1 is obtained in media containing either 1% corn steep liquor or 1 ...

β-d-Glucosidases from Sclerotium rolfsii
1988Publisher Summary Sclerotium rolfsii produces at least four different extracellular β-glucosidases when grown on cellulose. The four β-glucosidases from S. rolfsii are comprised of single polypeptide chains as the reduced carboxymethylated form of each enzyme shows one protein band on SDS-gel electrophoresis with relative molecular masses ...

Carboxymethylcellulase from Sclerotium rolfsii
1988Publisher Summary Carboxymethylcellulases are predominantly endoglucanases able to catalyze the hydrolysis of glycosidic bonds in the soluble, substituted cellulose, carboxymethylcellulose (CMC). These enzymes, formerly called C x , are important components of the cellulase complex that catalyzes the degradation of crystalline cellulose. This chapter

The production of sclerotia by Sclerotium rolfsii
Transactions of the British Mycological Society, 1965The effects of various levels of glucose, nitrate, thiamine, potassium and phosphate on the production of sclerotia by Sclerotium rolfsii Sacc. were investigated by appropriate modifications of a synthetic agar medium. In the absence of any one of these nutrients there was either no growth and no sclerotial production (glucose, thiamine), or growth was

The respiration of sclerotia of Sclerotium rolfsii
Mycopathologia et Mycologia Applicata, 1967The respiration of sclerotia ofS. rolfsii was investigated using the Warburg constant-volume respirometer to measure oxygen uptake. The effects of age of sclerotia, pH, and temperature were studied. Sclerotia produced on prune agar were ideal for respirometric studies, being uniformly round and of approximately equal size.

Production of carbohydrases by Sclerotium rolfsii.
Hindustan antibiotics bulletin, 1993Coproduction of alpha-amylase, beta-amylase, amyloglucosidase, cellulase, xylanase, pectinase and beta-galactosidase by Sclerotium rolfsii was studied on various polysaccharides. Starch induced alpha-amylase, beta-amylase, amyloglucosidase and beta galactosidase; cellulose induced cellulase, xylanase, pectinase and beta-galactosidase; and pectin ...

summaryIntact mature sclerotia of Sclerotium rolfsii sacc, and Sclerotium cepivorum Berk, produced in culture are impermeable to the apoplastic tracer sulphorhodamine G. Both of these species produce sclerotia with rinds. Some movement of sulphorhodamine into sclerotia of Rhizoctonia solani Kühn, which have no rind, occurred but the fluorochrome was ...

Microbial reduction of ethyl acetoacetate using Sclerotium rolfsii
Biotechnology Letters, 1989A method for the quantitative enantioselective bioreduction of ethyl acetoacetate [1] to optically pure (+)-S-ethyl-3 hydroxybutyrate [II] usingSclerotiumrolfsii mycelium is described. In a synthetic medium 1 g mycelium (dry weight) could convert 1 g of I to II within 2–3 days of fermentation (pH 5.8, 30°C).
