Abstract:
Synechocystis MCCB 114 and 115 were segregated as putative probionts for shrimp
larvae from a collection of 54 cyanobacterial cultures enriched from seawater. On feeding Penaeus
monodon post-larvae with the cyanobacteria, the generic diversity of the intestinal bacterial flora
could be enhanced with substantial reduction or total absence of Vibrio spp. A significant difference
(p < 0.001) in the percent survival of batches of post-larvae fed on the cyanobacterial cultures was
observed and, on repeated challenge with V. harveyi, the relative percent survival of those batches
of larvae fed on Synechocystis MCCB 114 and 115 was significantly higher. The Synechocystis
MCCB 114 and 115 cultures were found to contain high levels of protein (34 to 43%), in addition to
carotenoids
