A SURVEY OF THE PIGMENTS OF A NUMBER OF CHROMOGENIC MARINE BACTERIA, WITH SPECIAL REFERENCE TO THE CAROTENOIDS

Abstract
A survey of a number of chromogenic marine bacteria indicates the pigments present are generally carotenoids Polyhydroxyxanthophylls predominate and carotenes are rarely observed. This picture is also characteristic of non-marine bacteria. Pigment in Serratia marinorubra is prodigio-sin. High pressure has no effect on synthesis of carotenoids by marine bacteria.
