Optimization of medium components for maximizing the bacteriocin production by Lactobacillus plantarum ATM11 using statistical design

چکیده
In the present study, statistically based experimental design was applied for the optimization of bacteriocin production by Lactobacillus plantarum ATM11 isolated from goat slaughter house soil. Seven variables were chosen for Plackett-Burman design, in which three variables were screened as influencing factors: yeast extract, Tween 80 and K2HPO4. These three factors were subsequently optimized using Box-Behnken design and the optimal conditions were found to be 12.1 g/L for yeast extract, 2.5 g/L for Tween 80 and 1.99 g/L for K2HPO4. The validity of the optimal conditions was verified in a separate experiment.

Optimization of bacteriocin production by batch fermentation of Lactobacillus plantarum LPCO10.
Optimization of bacteriocin production by Lactobacillus plantarum LPCO10 was explored by an integral statistical approach. In a prospective series of experiments, glucose and NaCl concentrations in the culture medium, inoculum size, aeration of the culture, and growth temperature were statistically combined using an experimental 2(3)(5-2) fractional factorial two-level design and tested for the...
متن کاملCoculture with specific bacteria enhances survival of Lactobacillus plantarum NC8, an autoinducer-regulated bacteriocin producer, in olive fermentations.
Bacteriocin production in Lactobacillus plantarum NC8 is activated by coculture with specific bacteriocin production-inducing bacterial strains. The system is further regulated by a three-component regulatory system involving a specific autoinducer peptide (PLNC8IF). We have used L. plantarum NC8 as a starter culture in Spanish-style green olive fermentations and examined the influence of cocul...
متن کاملInduction of plantaricin production in Lactobacillus plantarum NC8 after coculture with specific gram-positive bacteria is mediated by an autoinduction mechanism.
Plantaricin NC8 (PLNC8), a coculture-inducible two-peptide bacteriocin from Lactobacillus plantarum NC8, has recently been purified and genetically characterized. Analysis of an 8.1-kb NC8 DNA region downstream of the PLNC8 operon revealed the presence of at least four operons involved in bacteriocin production, showing high homology to the plantaricin cluster in L. plantarum C11. However, we f...
متن کاملOptimization of Reduced Glutathione Production by a Lactobacillus plantarum Isolate Using Plackett–Burman and Box–Behnken Designs
In this work, we aim to optimize the production of reduced glutathione (GSH) synthesized intracellularly by a food-grade microorganism through a statistical approach. Using a colorimetric method, 25 Lactobacillus plantarum isolates were screened in an attempt to find a GSH-producing strain. It was found that 36% of the tested isolates showed positive result. Isolate (L7) was found to produce 15...
متن کاملBacteriocins from Lactobacillus plantarum – production, genetic organization and mode of action
Bacteriocins are biologically active proteins or protein complexes that display a bactericidal mode of action towards usually closely related species. Numerous strains of bacteriocin producing Lactobacillus plantarum have been isolated in the last two decades from different ecological niches including meat, fish, fruits, vegetables, and milk and cereal products. Several of these plantaricins ha...
