Small heat shock proteins are protective proteins produced by organisms under thermal stress. They are widely present in living organisms. Here, Hsp18, Hsp18.55 and Hsp19.5 genes were cloned from Lactobacillus plantarum and heterologous expressed in Lactococcus lactis, and their potential functions under ethanol stress were investigated. The results showed that the recombinant strain over expressing Hsp19.5 gene had stronger stress resistance, which provided a basis for further study of the survival ability of other microorganisms under ethanol stress.
Key words: Small heat shock proteins / Lactobacillus plantarum / heterologous expression / Lactococcus lactis / Ethanol stress
