Algicidal Potential of the Endosymbiont Bacterial Consortium of the Seagrasses Enhalus acoroides and Thalassia hemprichii

Abstract The isolate is the consortia of endosymbiont bacteria isolated from seagrasses E. acoroides and T. hemprichii . two isolates these bacterial can inhibit growth dinoflagellate Porphyridium sp. algicidal activities are 94.1% 92.8%, respectively. However, values BG plankton culture lower; they 57.1% 48.6%, respectively, which shows that seagrass endosymbionts group very good good. performance activity diatom relatively effective as for Nitzschia sp., ranging 44.9% to 52.6%; however, another low, be used source. In general, endosymbiont-bacterial consortium EhEd stronger than ThEd in target group. This fact makes it possible use a bio-agent overcome so-called algal bloom phenomenon affecting general culture.
