Production and properties of a lipopeptide biosurfactant from Bacillus subtilis C9
Abstract A lipopeptide biosurfactant, C9-BS produced by Bacillus (B.) subtilis C9, emulsified hydrocarbons, vegetable oil and crude oil. A high yield of C9-BS was obtained from a culture of B.Expand
Degradation of polyethylene by a fungus, Penicillium simplicissimum YK
Abstract We isolated a strain of Penicillium simplicissimum , YK, for use in the biodegradation of polyethylene, characterizing the fungus and examining how to treat the polyethylene beforeExpand
Use of Long-chain n-Alkanes (C13-C44) by an Isolate, Acinetobacter sp. M-1
A long-chain n-alkane-using microorganism was isolated from a soil sample, and was identified to belong to genus Acinetobacter, which could grow on the solid hydrocarbons without addition of any detergents. Expand
Purification and Characterization of Amidase which Participates in Nitrile Degradation
Amidase was purified from the cell-free extract of acetonitrile-grown Arthrobacter sp. J-1 by a procedure involving protamine sulfate precipitation, ammonium sulfate fractionation, and columnExpand
Isolation and characterization of a novel oxygenase that catalyzes the first step of n-alkane oxidation in Acinetobacter sp. strain M-1.
The enzymatic evidence strongly supports the existence of an n-alkane oxidation pathway, which is initiated by a dioxygenase reaction, in Acinetobacter spp. Expand
Alcohol oxidases of Kloeckera sp. and Hansenula polymorpha. Catalytic properties and subunit structures.
Alcohol oxidase (alcohol: oxygen oxidoreductase) of a thermophilic methanol-utilizing yeast, Hansenula polymorpha DL-1, was isolated in crystalline form and was more stable to heat than was the enzyme of Kloeckera sp.polymorpha, compatible with the difference in growth temperatures for both yeasts.

Screening for Tocopherol-producing Microorganisms and α-Tocopherol Production by Euglena gracilis Z
Various kinds of eucaryotic microorganisms were screened as to their tocopherol production by means of high performance liquid chromatography. Non-photosynthetic microorganisms did not produceExpand
Purification and Characterization of Benzonitrilases from Arthrobacter sp. Strain J-1.
Two kinds of benzonitrilases were found in a cell extract of Arthrobacter sp. Expand
A new enzymatic method of acrylamide production.
To produce acrylamide from acrylonitrile by use of a new enzyme, nitrile hydratase, a number of nitrile-utilizing microorganisms were screened for the enzyme activity by an intact cell system. AnExpand
Enzymatic determination of serum-free fatty acids: a colorimetric method.
Results on human sera correlate well with those obtained by the previously described enzymatic method and the chemical colorimetric method. Expand
