Abstract The biological characteristics of a novel prodigiosingenerating marine bacterium and the prodigiosin production were studied. The primary study on its morphological, culture and biochemical characteristics were carried out. The prodigiosin (PG) was sensitive to pH and ultraviolet radiation and it was the most stable at pH 3.0. The PG was not sensitive to temperature. Most metal ions had little effect on it. It was worthy to study as a kind of natural pigments and medical sources. ......
