Bacillus coagulans ATCC 8038 의 β- galactosidase 생산증진에 관한 연구
김현욱,안종건,권일경 한국낙농학회 1981 韓國酪農學會誌 Vol.3 No.2
This study was to stimulate β-galactosidase production of Bacillus coagulans ATCC8038, a thermophilic, sporeforming, and facultatively anaerobic lactose fermenting bacterium. Optimum initial pH for the enzyme production was pH 7.0 in the medium which contained 0.4% of lactose, 0.1% of peptone, 0.2 % of yeast extract, 0.7% Na-acetate. 3 H₂O and 0.03% CaCl₂.2H₂O. Potassium phospate buffer(0.05M, pH 7.0)induced the better production of β- galactosidase, and optimum concentrations of lactose, yemit extract, peptone and Na - acetate. 3H₂O in β-galactosidase production medium were found to be 0.4% , 1%, 0.1% and 0.7% respectively.

A Hanguel word processing software which could be ported into a general purpose microcomputer that has Z-80A CPU and FDOS operating system has been described in this paper. This software consists of input routine, processing routine, and output routine. In the input routine, Hanguel inputted linearly by the ASCII keyboard is combined into a character, and is displayed on the CRT screen in two-dimensional form. In the processing routine, any function among (1) editing (2) updating (3) printing (4) deleting could be selectively performed. In the output routine, Hanguel characters could be selectively printed in the 3 different sized character forms, i.e., 16×16 dot, 24×24 dot, and 32×32 dot size.
