Biosorption of silver cations onto Lactococcus lactis and Lactobacillus casei isolated from dairy products
The current work deals with the phenomenon of silver cations uptake by two kinds of bacteria isolated from dairy products. The mechanism of sorption of silver cations by Lactococcus lactis and Lactobacillus casei bacteria was investigated. Inductively coupled plasma-mass spectrometry (ICP-MS) was used for determination of silver concentration sorbed by bacteria. Analysis of charge distribution ...
متن کاملDevelopment of an Escherichia coli-Lactobacillus casei shuttle vector for heterologous protein expression in Lactobacillus casei.
There is an increasing interest to develop various lactic acid bacteria (LAB) species as mucosal delivery vehicles, for which the development of a variety of cloning and expression systems for these bacteria is of primary importance. This study reports the complete nucleotide sequence of the cryptic plasmid pRCEID7.6 derived from the chicken probiotic LAB strain Lactobacillus casei TISTR1341. S...

متن کاملIntroduction of peptidase genes from Lactobacillus delbrueckii subsp. lactis into Lactococcus lactis and controlled expression.
Peptidases PepI, PepL, PepW, and PepG from Lactobacillus delbrueckii subsp. lactis, which have no counterparts in Lactococcus lactis, and peptidase PepQ were examined to determine their potential to confer new peptidolytic properties to lactococci. Controllable expression of the corresponding genes (pep genes) was achieved by constructing translational fusions with the promoter of the nisA gene...
متن کاملبررسی اثر رشد و تکثیر تعدادی از باکتری‌های لاکتیک روی تحول میکروبی گوشت چرخ کرده گاو در شرایط صنعتی
The effects of growth of two strains of lactic acid bacteria on microbial flora of ground beef after packaging in air permeable packs were studied under workshop conditions. The strains isolated from dairy products were added to ground beef at a density of 104 CFU/g after identification and antibiosis test against indicator bacteria (Escherichia coli and Staphylococcus aureus). The two strains ...
