title: [Isolation and characterization of two marine algicidal bacteria against the Phaeocystis globosa].
abstract: The algae-lysis bacteria Y01 and Y04 were isolated from seawater, during a red tide survey of the Zhuhai Estuary in southern China. The algae-lysis bacteria Y01 and Y04 were Gram-positive bacteria which can remove P. globosa in 6 days. The lysing process was observed by microscope and SEM, both of them could directly lyse P. globosa. The strains were identified by the sequence analysis of 16S rDNA. The length of the two bacteria's sequences were 1 468 bp and 1 548 bp (strain Y01: DQ531607; strain Y04: DQ531608). The DNA sequence similarity searches showed that share more than 99.7% sequence homology with some strain of Bacillus. The algae-lysing bacteria would provide a possibility to control P. globosa red-tide by microbial agents.
