미생물 제재인 Bioenzyme은 호기성 조건하에서 총 세균수는
Bioenzyme was made up of two predominant strain, which were nomenclated PN-1 and PN-2, respectively. PN-1 possessed spore forming ability, motility, gram positive, catalase activity, but didn't have oxidase activity, urease activity, nitrate reduction and indole forming ability. Taxonomical characteristics of the PN-2 were similar to PN-1 strain, but colony color of PN-2 was yellow-white and nitrate reduction ability was positive. Predominant strains were ascertained by physiologically and morphologically. PN-1 and PN-2 were identified Bacillus lichenifonnis and Bacillus thuringinensis, respectively. Yield of lettuce significantly increased in first and second bioenzyme treatment. Fresh weight, length of shoot, width of leaves significantly increased in N,P,K and N,P,K followed by Bioenzyme application.
