【摘要】By using an LKB2277 Bioactivity Monitor, the power-time curves of Bacillus thuringiensis Cry B at 28℃ effected by Na2SeO3 were determined. Some paarameters, such as growh rate constant k, inhibitory ratio I, the maximum heat production rate Pmax, heat output Q, were obtained. Considering both the growth rate constant k and heat output Q, it was found that a low concentration of Na2SeO3 had a promoting action on the growth of Bacillus thuringiensis Cry B, but a high concentration of Na2SeO3 had an inhibitory action. 【总页数】4页(562-565)
