摘要:
A process for preparing enantiomerically pure lactams of the formula I ##STR1## where R.sup.1 and R.sup.2 are each, independently of one another, H, unsubstituted or substituted C.sub.1 -C.sub.4 -alkyl, unsubstituted or substituted C.sub.2 -C.sub.4 -alkenyl, unsubstituted or substituted aryl, (CH.sub.2).sub.n --COOH with n=0, 1, 2, 3, and X is 1, 2, 3, 4, 5, from a racemate of the formula I by. allowing a biocatalyst which selectively converts one enantiomer from I to act on the racemic mixture of I, and isolating the unconverted enantiomer from the resulting mixture of products.
摘要:
The invention relates to a novel process for preparing 3-hydroxyphenylacetic acid by cultivating a fungus of the genus Rhizoctonia, Ceratobasidium and Pellicularia in the presence of a phenyl compound of the formula I ##STR1## where X is COOR, CH.sub.2 OH, CH.sub.2 NH.sub.2 or ##STR2## R is methyl, ethyl, hydrogen, sodium, potassium or ammonium.
摘要:
A process for hydroxylating compounds of the formula ##STR1## where n, A and R.sup.1 to R.sup.4 have the meanings stated in the description, with the aid of microorganisms of the genus Beauveria.
摘要:
The present invention relates to a novel process for the preparation, by fermentation, of compounds of the formula I ##STR1## where R.sup.1 is hydrogen, fluorine, chlorine or bromine.
摘要:
A process for producing optically active primary and secondary amines from the corresponding racemates is characterised in that (a) a racemic amine is enantioselectively acylated in the presence of a hydrolase with an ester whose acid component bears a fluorine, nitrogen, oxygen or sulphur atom at the proximity of the carbonyl carbon atom; (b) the mixture of optically active amine and optically active acylated amine is separated so that an enantiomer of amine is produced; (c) if desired the other enantiomer of the amine is extracted from the acylated amine by amide cleavage.
摘要:
A process for producing microorganisms which have increased L-lysine productivity is described. The process makes use of microorganisms of the genera Corynebacterium and Brevibacterium which are resistant to feedback inhibition by 2-azido-.epsilon.-caprolactam.
摘要:
A process is disclosed for preparing D,L-aspartic acid by beating aqueous solutions of ammonium salts of the maleic acid. The molar ratio of maleic acid to ammonia ranges from 1:1 to 1:50. The process is carried out at temperatures from 60.degree. to 250.degree. C. and pressures of at least 1 bar. The pressure applied during the reaction is adjusted to ensure that the reaction mixture is almost completely present in liquid phase. Excess ammonia is removed and the reaction solution is acidified so as to release D,L-aspartic acid, which is then isolated.
摘要:
A method for computer-based processing of biological data, comprising the steps of: selecting a gene as lead gene to be patented; searching homologues for the selected lead gene; creating a patent pool on the basis of the selected lead gene; generating and outputting a pool report for the planned patent application.
