Isolation and Characterization of an Algicidal Bacterium in biofilm on submerged reed stems for control of Microcystis blooms

From the reed surficial biofilm isolated a strain of algicidal bacteria B2 have significant algicidal effect of Microcystis aeruginosa. By means of microscope and scanning electron microscope and monitoring the change of pH in the medium of B2, we found that the dissolved algae bacteria B2 was dissolved in algae. Algicidal way for bacteria secrete soluble active substances Algicidal algae. Analysis of 16S rDNA sequence revealed that strain B2 belonged to the genus Brevundimonas. By 16S rRNA sequence analysis and data in GenBank homology search, combined with morphological, physiological and biochemical characteristics of the bacterial strains belonging to the genus Bacillus.
