Methods: The marine bacteria were isolated with the infinite dilution and plate streak technique and screened for antimitosis active strains by Pyricularia Oryzae model. The active strain 32-11-2-2 was subjected to morphological, physiological and biochemical study, and was classified by the analysis of the 16S rDNA sequence. Results A total of 421 strains of marine bacteria were isolated from marine water and sediment samples; 54 of them had antimitotic activity.
