Description
Summary:Bacterial strain used in this study was isolated from sediment obtained from Sepanggar Bay. The strain was identified as Bacillus coagulans through some biochemical and morphological tests. This study was conducted to study probiotic effects of B. coagulans in live feed, especially on Artemia. The live feed was fed with cod oil juice (1 ml), mixture of cod oil juice and B. coagulans, and B. coagulans (1.84x10-3 mgl⁻¹). In control live feed was not fed and leaved starved. The study indicated that the probiotic strain improves the growth (3.58 mm) and survival (60%) of Artemia. Artemia fed with a mixture of B. coagulans and cod oil juice showed a growth of 3.58 mm whereas Artemia fed with B. coagulans alone showed a growth of 2.40 mm. Significantly higher growth (P<0.05) was recorded in Artemia fed with the mixture of probiotic and cod oil juice. Artemia fed with probiotic alone showed significantly higher survival (P<0.05) compared to Artemia fed with other feeds. The study signifies that the use of B. coagulans does increases the growth and survival of Artemia compared to control or cod oil juice. Therefore, can be concluded that B. coagulans has potentiality as probiotic. Hence, B. coagulans can be applied as probiotic for a sustainable aquaculture.
