Utilization of arylaliphatic nitriles by haloalkaliphilic Halomonas nitrilicus sp. nov. isolated from soda soils

An enrichment culture from saline soda soils, using acetate as carbon and energy source and 2- phenylpropionitrile as nitrogen source (PPN) at pH 10, resulted in the isolation of strain ANL-?CH3. The strain was identified as a representative of the genus Halomonas in the Gammaproteobacteria. The bacterium was capable of PPN utilization as a...

Method of preparing cross-linked enzyme particles

The invention relates to a method of preparing cross-linked enzyme particles using a cross-linking agent. According to the invention, the enzyme particles are formed and subsequently cross-linked using a cross-linking agent having at least n reactive groups where N>=3 and a molecular weight of >2,000 Da. The method according to the invention...

A method of preparing cross-linked enzyme aggregates

The invention relates to a method of preparing cross-linked enzyme aggregates (CLEAs) comprising the steps of a) precipitating a dissolved enzyme present in a liquid medium; b) cross-linking with a cross-linker, and c) optionally, washing the cross-linked enzyme aggregate. According to the invention at least one treatment is performed chosen...

Process for the preparation of alkyl glycosides

Abstract of WO 9636640 (A2) The present invention relates to a process for the preparation of alkyl glycosides by reacting an alcohol with a saccharide or a lower-alkyl glycoside in the presence of a catalyst, wherein the catalyst is a mesoporous silica-based molecular sieve material. This process allows to produce alkylated mono- and...

A PROCESS FOR CARRYING OUT ENZYMATICALLY CATALYZED CONVERSIONS OF ORGANIC COMPOUNDS

Abstract of WO 9507359 (A1) A process for carrying out enzymatically catalyzed conversions of organic compounds comprises reacting an ester of an organic acid in a liquid organic phase with ammonia in the presence of a hydrolytic enzyme such as a lipase, esterase or protease. The process permits the highly enantioselective preparation of...

Dewar-benzene derivates: Synthesis, isomerization, hydrogenation

Hydrogenation and hydrogenolysis in synthetic organic chemistry

The major aim of this book is to provide preparative organic chemists with the insight and the know-how necessary to apply catalytic hydrogenation and hydrogenolysis to synthetic problems. Several texts on hydrogenation and hydrogenolysis are available, but the authors feel that many chemists will welcome a book in which more attention has been...
