Abstract
Spores obtained from Bacillus cereus ATCC 14579 and mutant strains lacking each of seven germinant receptor operons were exposed to differentiated Caco-2 cells and monitored for germination. Spores of the gerI and gerL mutants showed a reduced germination response, pointing to a role for these receptors in Caco-2-induced germination.
摘要
从蜡样芽孢杆菌ATCC 14579及缺失七个发芽受体操纵子中每一个的突变菌株获得的孢子，被暴露于分化的Caco-2细胞，并监测其发芽情况。gerI和gerL突变体的孢子显示出发芽反应降低，表明这些受体在Caco-2诱导的发芽中起作用。
