Influence of several gums on the growth and the production of a bacteriocin like substance from Lactobacillus curvatus/sakei ACU-1

The study was meant to evaluate the influence of xanthan gum, λ-carrageenan, arabic gum and tragacanth gum on the growth and . in situ production of bacteriocin like inhibitory substances from . Lactobacillus curvatus/sakei ACU-1. . Listeria innocua ATCC 33090 and . Staphylococcus aureus FBUNT were...
