摘　要：摘 要：芽孢杆菌休眠孢子的萌发是孢子恢复到营养生长的第一个决定性步骤。孢子被营养性萌发剂和各种非营养信号诱导而萌发恢复到营养细胞状态。芽孢萌发后就丧失了对外界胁迫的抵抗力。该文主要从芽孢萌发信号传导、营养萌发受体、萌发中的离子通道、皮层溶解酶的功能、非营养诱导萌发和萌发途径等方面阐述芽孢杆菌孢子萌发机理的进展，并对其前景作了简要评述。

Abstract: Abstract: The germination of Bacillus spores is the first step to return the vegetative growth， and is induced by nutrients and a variety of non-nutrient agents， and spores completely lose resistance to outer stress after germination. This paper introduced the signal transduction of spores germination， receptors of nutrient germinants， ion fluxes in germination， the role of cortex lytic enzymes， nonphysiological germination and the latest research progress of spores germination pathway.
