Abstract
Bacillus thuringiensis var. thuringiensis H1 (BTT) strain was cultured in the 4 different fermentation media and then measured their growths and the productions of endotoxin crystals from the culture media. Out of the 4 media, the productions of the endotoxin crystals and spores were maximal in the pH9-M-3 medium. The wet weight of BTT cells grown in the 150ml culture was approximately 3.218g and the number of the viable spores was
Bacillus thuringiensis var. thuringiensis H1균을 4종류의 배지에서 배지 조성 및 pH 조건에 따라서 성장 양상과 아포와 내독소 결정체 생산을 조사했다. 1. 4개의 M-배지중 pH 9인 M-3배지에서 BTT의 증식량과 내독소 결정체 및 아포 생산수가 가장 높았다. 150ml배양에서 BTT의 생산량은 3.218g이었고, 생존 아포수는 ml당
