Activity dynamics and regulation mechanism of extracellular proteases in <i>Bacillus velezensis</i> SW5.

ABSTRACT: Bacillus velezensis is capable of producing and secreting a rich variety of proteases, making it an excellent catalyst for food fermentation and bioremediation, as well as a promising source of proteases with industrial application potential. However, our knowledge of the activity and regulation mechanism of extracellular proteases in B. velezensis during growth remains limited. In our study, we investigated the growth dynamics, extracellular protease activity, and transcriptional profiles of B. velezensis strain SW5 over the course of the incubation period. The growth dynamics analysis showed that the cell density of SW5 increased exponentially until 10 h post-incubation, then declined or remained stable afterward. However, the extracellular protease activity followed
