【 摘 要 】

:The purpose of this research was to investigate the progress of the rancidity in Nile tilapia diets containing bacterial biomass of Rubrivivax gelatinosus. Six experimental treatments comprised basal diet (negative control), diet with asthaxanthin (positive control) and 4 diets with different concentrations of the bacterial biomass. The thiobarbituric acid assay for rancidity analyses were accomplished after 6 and 12 months of diets storage. It was concluded thatRubrivivax gelatinosusbiomass minimized the racidity in Nile tilapia diets in 32.52 to 44.72% at 6 months and in 37.85 to 52.37% at 12 months of storage.
