The Prolongation of Life(Mechnikov, 1907) published over 100 years ago reported scientific research on the physiological activity of lactobacillus. Dead lactobacillus has long been used as medicine at home and abroad. Recent studies focus on various peptide and polysaccharide substances produced by lactobacillus or the physiological activity of dead lactobacillus after thermal treatment in addition to the settlement of viable lactobacillus in the intestine. There are especially active studies on the effects of dead lactobacillus on immune activity. It has been reported that dead lactobacillus has the same or higher effects on immunity and probiotic action compared with live lactobacillus. In CIB001 HK, CELLINBIO turns Lactobacillus plantarum independently separated from kimchi into dead lactobacillus via a special patent technique by a FDA-registered contractor to provide it as a food material.
