BACKGROUND Lactobacillus plantarum constitutes a well-recognized food-grade system for the expression of recombinant proteins in the field of industrial and medical biotechnology. For applications in vivo or in biotechnological processes, the level of expression of e.g. antigens or enzymes is often critical, as expression levels should be of a certain effectiveness, yet, without putting too muc...

introduction: lactic acid bacteria are widely used for the fermentation and preservation of dairy and meat products and to improve their aroma and texture. the aim of this study wasto screen lactobacillus plantarum isolated from sausage for detection of plasmids, protein bandsand phages, to find possible linkage of bacteriocin production to genetic location. material and methods: two lactobacil...

the species of lactobacillus are widely present in many natural environments that areimportant in fermented processes. among these species some belong to the lactic acid bacteria group that areuseful in fermented food. one of the species of lactobacilli group such as l. plantarum provides health benefits,but their identification is one of the main issue. in order to proceed with this project, c...

Summary: A web-based visualization tool, the Microbial Genome Viewer, is presented which allows the user to combine complex genomic data in a highly interactive way. This web tool enables the interactive generation of chromosome wheels and linear genome maps from genome annotation data stored in a MySQL database. The generated images are in Scalable Vector Graphics (SVG) format, which is suitab...

in this study, phenolic compounds of evening primrose leaves (oenothera biennis) were extracted with aceton 70%, ethanol 70% and methanol 70%. total phenolic content of aceton extract was significantly higher than the ethanolic and methanolic extracts. extracts were tested for their antimicrobial activity against lactobacillis plantarum and saccharomyces cerevisiae, using micro broth dilution m...

Background: Lactic Acid Bacteria are a group of Gram-positive bacteria which are widely used in the food industry as organic ferments called starter cultures. In this study, Enterococcus faecium, Leuconostoc mesenteroides, Lactococcus lactis, Weissella paramesenteroides, and Lactiplantibacillus plantarum isolated from Moroccan table olives were tested for their acquisition of probiotic and tech...

abstract: acidophilus milk after preparation, with the defined characteristics of ph, titratable acidity and viable counts of lb. acidophilus, was kept at the refrigerator (5 °c) and changes of above mentioned parameters were evaluated during 21 days at 7-day intervals. the obtained results showed that the titratable acidity of product significantly (p≤0.05) increased over storage period, demon...
