Abstract

A bacterium coded as strain HAP-1 was isolated from a municipal anaerobic digestor for its ability to reduce >7000 ppm perchlorate in wastewaters. The organism is capable of the dissimilatory reduction of perchlorate on chlorate to chloride for energy and growth. It is a Gram-negative, non-sporeforming, obligately anaerobic, motile thin rod. Antibiotic resistance, utilization of carbon substrates and utilization of electron acceptors by bacterium HAP-1 were similar toWolinella succinogenes. The organism's 16S rRNA sequence was 0.75% different from that of the type strain ofW. succinogenes. The fatty acid compositions of the two organisms are very similar. The morphological, physiological and 16S rRNA sequence data indicated that bacterium HAP-1 is a strain ofW. succinogenes that can utilize perchlorate or chlorate as a terminal electron acceptor.
