The crude extract from the cells contained two major components, lower molecular and higher molecular ones responsible for the antibiotic and autotoxic activities. The higher molecular component may composed of the lower molecular component and other cellular materials. The lower molecular substance was purified by using DEAE-sephadex A-50 chromatography, Toyopearl HW-55 gel filtration and polyacrylamide gel electrophoresis. The purified substance was shown to be heat-labile but relatively stable to a wide range of pH and to have an approximate molecular weight of 50,000.}, pages = {29--37}, title = {Antibiotic Production by Marine Pigmented Bacteria II : Purification and Characterization of Antibiotic Substance of Alteromonas luteoviolacea}, volume = {35}, year = {} }
