Abstract
Twelve strains of algicidal bacteria were isolated from the surfacewater of the pond Shinobazu and the moat Ote-bori (Tokyo, Japan). Nine of thesestrains were considered to be in the Pseudomonas group byanalyses of 16S rDNA sequences. The methanol extract ofPseudomonas sp. K44-1 showed marked antialgal activity bythe paper disk method. Harmane (1-methyl-β-carboline) was isolated fromtheethyl acetate extract of the whole culture broth ofPseudomonas sp. K44-1 by using silica gel columnchromatography and high performance liquid chromatography (HPLC). Harmaneshowedantagonistic activities against several cyanobacterial strains at aconcentration of 30 μg disk−1.
