2022-2-10·Probiotics confer health benefits to the host, and their application to control infectious diseases in aquaculture is well recognized. Probiotic bacteria exert beneficial effects in fish/shellfish when applied through the feed. Besides the application of probiotics as a feed additive, an additional concept of “water probiotic” is also ...
2016-7-5·For the control, no probiotic was added. Experiment 2: Tilapia were housed in cages for 42 days, and the feed was supplemented with B. cereus at 1.0 × 10 7 cfu g −1 (Treatment 1) and 1.0 × 10 8 cfu g −1 (Treatment 2) weekly. For the control, no probiotic was added. Each treatment contained three replicates, with 50 male tilapias per ...

2016-7-1·Fish were fed a basal diet (control check group, CK group) supplemented with B. subtilis (1 × 108 CFU/g feed, BS group), B. cereus NY5 (1 × 108 CFU/g feed, BC group), and B. subtilis + B. cereus ...
2021-7-1·This study was conducted to evaluate the probiotic potentiality of Streptomyces antibioticus and Bacillus cereus isolated from the digestive tract of earthworm, Eisenia fetida.. Based on recent investigations (in-vitro and in-vivo assessment), this work concludes that Streptomyces antibioticus could form a promising potential probiotic for …
2013-6-1·ABSTRACT. In this preliminary study, we evaluated the effects of a gram-positive soil bacteria Bacillus cereus var. toyoi on the growth performance, digestive enzyme activities, intestinal morphology, and microbiota in rainbow trout Oncorhynchus mykiss fingerlings. Trout were maintained in a recirculation system and fed 2 diets: 1) a …
