A small heat shock gene of Lactobacillus plantarum strain WCFS1 was deleted using a Cre-lox based system. Compared to the wild type, the ∆hsp 18.55 mutant strain displayed a similar growth rate when cultivated either under optimal temperature or under different stress conditions such as heat, low pH and salt stress. However, a longer lag phase was observed when the ∆hsp 18.55 mutant strain was cultivated under short intense heat stress (50 °C). This suggests that the hsp 18.55 gene of L… CONTINUE READING
