Abstract

A protease-producing bacterium from sea cucumber intestinal tract was isolated and identified. Through morphological, physiological, biochemical characterization and 16S rDNA sequence homology analysis, the isolated strain was identified as Thalassobacillus sp. QDHF-1. Sea cucumber intestine waste was fermented by strain QDHF-1, and the fermentation conditions were optimized and the antioxidant activities of produced peptides were determined. The optimal fermentation condition to produce peptides was 6% inoculum, 20% raw materials and 36 h fermentation. The polypeptides could scavenge ·OH, DPPH·, and O-2·, and the highest scavenging rate of 93.94% was obtained on ·OH using 50 g/L polypeptides. The results indicate the potential applications of strain QDHF-1 in sea cucumber offal fermentation to produce bioactive peptides.
