This study aimed to examine the effect of using different semi-solid media, namely cassava dregs, tofu dregs, and molasses, on the growth of lactic acid bacteria (LAB) and bacteriocin production, as well as to characterize the properties of the bacteriocins produced. Bacteriocin production was influenced by LAB cell density, where the average LAB growth of 8.66 ± 109 in 1 mL of culture indicat…
