The prmi ary study on itsmorpholo ical, culture and biochem ical characteristicsw ere carried out. The prodi iosin ( PG) w as sensitive to pH and ultraviolet radiation and itw as the most stable at pH 3. 0. The PG w as not sensitive to temperature. M ost metal ions had little effect on it. Itw asw orthy to study as a kind of natural piments andmedical sources. K ey words marine bacterium; prodi iosin; piment , , 1 [ 1] ;
