Probiotics enhance resistance to Streptococcus iniae in Nile tilapia (Oreochromis niloticus) reared in biofloc systems.

Biofloc technology is a rearing technique that maintains desired water quality by manipulating carbon and nitrogen and their inherent mixture of organic matter and microbes. Beneficial microorganisms in biofloc systems produce bioactive metabolites that may deter the growth of pathogenic microbes. As little is known about the interaction of biofloc systems and the addition of probiotics, this study focused on this integration to manipulate the microbial community and its interactions within biofloc systems.

Draft Genome Sequences of Cetobacterium somerae 2G Large and Two Novel Isolates from Intestines of Channel Catfish ().

We report the draft genome sequences of 2G Large and two isolates, 2A and 8H, which may represent novel species. The isolates were recovered from the intestines of catfish, and the genomes will assist in research to understand their potential use as probiotics in aquaculture.
