<i>Hsp</i> from <i>Lactobacillus plantarum</i> Expression in <i>Lactococcus lactis</i> MG1363

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