The algicidal strain was identified as Pseudomonas sp. tentatively on physiological and biochemical examinations. Pseudomonas sp. C55a-2 was demonstrated to produce an algicidal substance extracellularly in marine nutrient medium Z-CII. An algicidal substance was purified from the culture supernatant of strain C55a-2 by a series of purification steps including ethyl acetate extraction, Sep-Pak treatment, Sephadex LH-20 column chromatography and high performance liquid chromatography (HPLC) with Mightysil RP-18GP column. The substance was shown to have algicidal activity against Chaetoceros ceratosporum, Chattonella marina and Heterosigma akashiwo strains by use of a microplate culture method.}, pages = {17--25}, title = {Purification of an Algicidal Substance Produced by Marine Pseudomonas sp.
