Chemostat production of plantaricin C by Lactobacillus plantarum LL441

Article Abstract:

Research was conducted to examine the chemostat production of plantaricin C by Lactobacillus plantarum LL441. L. plantarum LL441 was developed in MRS broth to stationary phase,, concentrated 10-fold in fresh MRS containing 220% glycerol and stored at -20 degrees C. Plantaricin C production was examined by the agar well diffusion test with Lactobacillus sake as the indicator strain. Results raise the possibility of increasing production experiments pertaining to plantaricin C to pilot plant assays.

Inhibition of Vibrio anguillarum by Pseudomonas fluorescens AH2, a possible probiotic treatment of fish

Article Abstract:

The inhibition of the fish pathogen Vibrio anguillarum by the antibacterial strain Pseudomonas fluorescens strain AH2 has been assessed. The inhibitory effect of the latter was studied under iron-rich and iron-limited conditions. Results indicated that the growth of V. anguillarum can be controlled by the iron-limited sterile-filtered culture supernatants of P. fluorescens. However, the growth of V. anguillarum cannot be stopped by the sterile-filtered supernatants under iron-rich conditions.
