Abstract：A strain of marine algae-lysing bacterium designated as JZ-1 was isolated from Jiaozhou Bay, China. Strain JZ-1 showed highly homology with Alteromonas sp. on the basis of morphological and biochemical characteristics and16S rDNA sequence analysis. Strain JZ-1 showed significant algicidal activity against Skeletonema costatum, it broke the materials structures in membrane and membrane integrity, and the materials leak through membrane to make the cells die. In addition, algicidal activity against S. costatum was detected in the filtrate and after filter through 0.2 μm syringe filter, not in the cells. Strain JZ-1 effects S. costatum by releasing certain algicidal substances, and this point was also confirmed by paper disk method. The metabolite had the highest algicidal activity at this moment when the bacterium transited to stationary phase from logarithmic growth phase. We tested some characteristics of the metabolite and the results were as follows: the molecular weight of metabolite was<5kD; the metabolite had certain acid tolerance but no alkali tolerance; the metabolite had thermal stability.
