Abstract

In this review, we investigate the immobilization of Lactococcus lactis spp lactis 1 in bacterial cellulose and application for producing bacteriocin. The results are given as following: - BC entirely satisfied the conditions required for immobilizing bacterial cell technology. - The effect of using Lactococcus lactis spp lactis 1 cell, immobilized in BC, for producing bacteriocin was hight: it could be reused about 9-10 times, the quantity and quality of bacteriocin remained rather good against control experiments. - Application of this bacteriocin, we us it to preseving pork. In turn, bacterial cellulose membrane treated with bacteriocin solutions which enhibit bacteriocin activity about 200 AU/ml. Using this preparation to enveloping pork samples and maintaining at 10-15oC. After three days, comparation of sample and control experiment has many differences in ceptor quality.
