| Abstract;Four microalgal strains, NN-G, TB-G, CC-B, and SC-B isolated from green water of tilapia culture ponds in the Philippines were cultivated in 10ml of ESS liquid medium at 23.DEG.C. with a 12h light-12h dark cycle. The cell forms of NN-G and TB-G were green small round and green large oval, respectively, while both CC-B and SC-B had brown cubic or quadrangular cells. Predominant bacteria isolated from the four microalgal cultures were commonly restricted to Moraxella-Acinetobacter group, Pseudomonas and Flavobacterium. Strains NN-G and TB-G contained chlorophyll b, chlorophyll a, violaxanthin and zeaxanthin, while strains CC-B and SC-B possessed chlorophyll c, chlorophyll a, and fucoxanthin as major pigments. Phylogenetic analysis based on SSU rDNA sequences demonstrated that strains NN-G, TB-G, CC-B and SC-B have close taxonomic relationships with Chlorella spp., Tetraselmis spp., Chaetoceros spp., and Chaetocertos spp., respectively.
