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.
