Abstract:
In this study, an attempt is made to evaluate the
performance of the microalga Chaetoceros muelleri when cultured with
a potential probiotic bacterium Vibrio alginolyticus strain C7b as
compared when both are cultured alone in medium f/2. Strain C7b grew
significantly better and lasted longer when grown with the microalga than
when grown alone. The microalga density was not affected by the presence of
the bacteria compared when grown alone. C. muelleri and the bacterial
strain C7b can be cultured together for up to 9 days to achieve a high
density (5.15×106 and 6.63×104 cell ml-1,
respectively) and then fed to the protozoeal and mysis stages of penaeid
shrimp.
