Abstract

Phenotypic and chemotaxonomic characteristics of four isolates of yeast-lysing bacteria isolated from wastewater treatment systems were examined. The isolates were nonsporeforming, gram-positive, facultative anaerobic, irregular rods that were motile by multitrichous flagella. The isolates had an absolute requirement for hemin or hemoproteins for aerobic growth. Under anaerobic conditions, the isolates did not need heme compounds, but needed carbon dioxide. The deoxyribonucleic acid (DNA) base composition was 65.7 to 66.1 mol% guanine plus cytosine. The amino acid composition of the cell wall peptidoglycan was -alanine, -alanine, -glutamic acid, -ornithine, and -serine (1:1:2:1:1). The major fatty acid of whole cells was 12-methyltetradecanoic acid. The major isoprenoid quinone was menaquinone with nine isoprene units. DNA-DNA hybridizations revealed clear separation of the isolates from known genera of the coryneform group. Therefore, gen. nov., sp. nov., is proposed for the isolates. The type strain is YLM-1 (JCM 6097).
