Temporal variation of seasonality of egg production and the spawning biomass of Pacific anchovy, Engraulis japonicus, in the southern waters of Korea in 1983–1994
Embryonic mortality, egg production and the spawning stock biomass of Pacific anchovy, Engraulis japonicus, off Southern Korea during 1983–1994, and their biological response to oceanographicExpand

Cloning and characterization of a novel thermostable esterase from Bacillus gelatini KACC 12197.
A novel gene encoding a thermostable esterase (designated as Est-gela) was isolated from the moderate thermophile Bacillus gelatini KACC 12197. The open reading frame of this gene (1170 bp) encodesExpand

Improved 1,3-propanediol production by Escherichia coli from glycerol due to Co-expression of glycerol dehydratase reactivation factors and succinate addition
Escherichia coli was engineered to produce 1,3-propanediol (1,3-PDO) from glycerol, an inexpensive carbon source. This was done by introducing a synthetic pathway consisting of glycerol dehydratase,Expand

Age, Growth, and Maturity of Chub Mackerel off Korea
Abstract The age, growth, and maturity of chub mackerel Scomber japonicus were determined by otolith analysis and gonad observation. Fish were subsampled monthly from Korean offshore commercialExpand

Fecundity and growth-dependent mortality of Pacific anchovy (Engraulis japonicus) in Korean coastal waters
Abstract We propose a method of estimating natural mortality of marine pelagic fishes, especially for early-life stages, based on their fecundity. To estimate size-dependent fecundity, growth andExpand

Improved enantioselectivity of thermostable esterase from Archaeoglobus fulgidus toward (S)-ketoprofen ethyl ester by directed evolution and characterization of mutant esterases
Thermostable esterases have potential applications in various biotechnology industries because of their resistance to high temperature and organic solvents. In a previous study, we isolated anExpand

Improving the enantioselectivity of an esterase toward (S)-ketoprofen ethyl ester through protein engineering
Abstract Esterases, enzymes that hydrolyze ester bonds, have been utilized to synthesize optically pure compounds like (S)-ketoprofen, which can be produced by the esterase-catalyzed hydrolysis ofExpand

Optimization of alkaline pretreatment on corn stover for enhanced production of 1.3-propanediol and 2,3-butanediol by Klebsiella pneumoniae AJ4
Corn stover is one of the most promising lignocellulosic biomass that can be utilized for producing 1,3-propanediol and 2,3-butanediol. The pretreatment and enzymatic hydrolysis steps are essentialExpand
