Purification, properties, and partial amino acid sequences of thermostable xylanases from Streptomyces thermoviolaceus OPC-520
Two types of xylanases isolated from the culture filtrate of a thermophilic actinomycete, Streptomyces thermoviolaceus OPC-520, degraded xylan, producing xylose and xylobiose as the predominant products, indicating that they were endoxylanases.
Purification and properties of three types of xylanases produced by an alkalophilic actinomycete
Three types of xylanases (l,4-β-D-xylan xylanohydrolase, EC were isolated from the culture filtrate of an alkalophilic actinornycete, Nocardiopsis dassonvillei subsp. alba OPC-18. The
Isolation of cytotoxic substance, kalafungin from an alkalophilic actinomycete, Nocardiopsis dassonvillei subsp. prasina.
The isolation of kalafungin from an alkalophilic actinomycete and its cytotoxicity are reported for the first time in this paper.
Living and highly syndiotactic polymerization of methyl methacrylate and other methacrylates by tert‐butyllithiumtrialkylaluminium in toluene
Highly syndiotactic poly(methyl methacrylate)s (PMMAs) with narrow molecular weight distribution (MWD) were prepared by polymerization of MMA in toluene at low temperatures, initiated with
