Cover Story: Aquaculture is the fastest-growing food-producing sector; however, due to its intensification, infectious diseases pose a major threat. Regarding this, probiotics are a viable alternative to traditional chemotherapy agents. Lactococcus lactis subsp. cremoris WA2-67 has previously demonstrated several probiotic features, including a strong antimicrobial activity against ichthyopathogens. Its whole-genome sequence (WGS) reveals the bacteriocinogenic genetic clusters encoding the lantibiotic nisin Z and two new bacteriocins, in addition to several probiotic traits, as well as the absence of transferable antibiotic resistances and genes encoding detrimental enzymatic activities and virulence factors. All these results support the use of L. cremoris WA2-67 as a probiotic for aquaculture. View this paper
