The Screening, Identificating and Ion Beam Mutagenizing of the Microbial Strains for Enantioselective Separation of Ibuprofen and Studying the Characterization of the Lipase
The pre-screening and rescreening were used to isolate the strain which was high preference for enantioselective hydrolysis of S-ibuprofen ethyl-ester to the corresponding S-ibuprofen. It was identificated by studying the physiological and biological characteristics and determining the large-subunit (26S) rDNA gene D1/D2 domain sequences of the strain. The result showed that the strain T was Trichosporon lactis.Low energy N+ ion beam(implanted with 30 keV, 1-5 X 10~15ions/cm~2) mutant strain, Trichosporo. l...
