Abstract
Studies were carried out on the inhibitory effect of NH4+ on germination of spores of Bacillus cereus T induced by L-alanine and inosine. Kinetic analysis showed that NH4+ inhibited the germination competitively. Its inhibitory effect was greater when the unactivated spores had been preincubated with L-alanine. NH4+ did not inhibit the response of unactivated spores to L-alanine during preincubation. These results suggest that L-alanine sensitizes the spores to the inhibitory effect of NH4+.
摘要
研究了NH₄⁺对L-丙氨酸和肌苷诱导的蜡样芽孢杆菌T孢子萌发的抑制作用。动力学分析表明，NH₄⁺竞争性抑制萌发。当未活化的孢子与L-丙氨酸预孵育时，其抑制作用更强。在预孵育过程中，NH₄⁺不抑制未活化孢子对L-丙氨酸的反应。这些结果表明，L-丙氨酸使孢子对NH₄⁺的抑制作用敏感。
