Abstract

A strain (KRED) that formed endospores and produced the pigment prodigiosin was isolated from activated sludge. The presence of spores in cells of strain KRED was evident upon electron microscopy examination, heat treatment and the detection of dipicolinic acid in the cells. Biochemical characteristics, and 16S rDNA sequence and DNA–DNA homology data identified strain KRED as . The major respiratory quinone of strain KRED was found to be ubiquinone Q-8. The formation of endospores by Gram-negative bacteria has not been observed previously, and has never been reported in any species of . Here, it is shown that strain KRED (JCM 11315=CIP 107489) represents a novel subspecies of , for which the name subsp. is proposed.
