摘要:The present invention relates to a novel epoxide hydrolase enzyme which aims to achieve a high degree of resolution towards a broader range of substrates with high enantioselectivity and yields with minimal product inhibition. The invention further relates to a new bacterial strain Achromobacter sp. MTCC 5605 isolated from a petroleum-contaminated sludge sample, capable of producing the said enzyme. It is notable that the enzyme can be used as whole bacterial cell preparation, which allows continuous hydrolysis of substrates at even higher concentration and have an advantage of being recycled. The invention further relates to a process for the hydrolysis of different aryl epoxides which are potential synthons of intermediates for the synthesis of chiral amino alcohols and bioactive compounds like β-blockers.

摘要:PCT No. PCT/FR84/00092 Sec. 371 Date Dec. 10, 1984 Sec. 102(e) Date Dec. 10, 1984 PCT Filed Apr. 6, 1984 PCT Pub. No. WO84/04097 PCT Pub. Date Oct. 25, 1984.The invention relates to acrylic telomers with grafts which can be cross linked by light, methods of synthesizing them and their applications. The telomers comprise a telogen of the mercaptan family, in particular dodecanethiol, and links of a taxogen of the acrylic family, some of which are grafted. The telomers are synthesized semi-continuously by radical initiation in the presence of initiators such as azobisisobutyronitrile, at a temperature below 75 DEG C., making it possible to obtain a number of links adapted to the desired applications. Grafting is carried out by means of glycidyl and aziridinyl groups.
