Bryobacter aggregatus gen. nov., sp. nov., a peat-inhabiting, aerobic chemo-organotroph from subdivision 3 of the Acidobacteria

Bryobacter aggregatus gen. nov., sp. nov. is proposed to accommodate three strains of slowly growing, chemo-organotrophic bacteria isolated from acidic Sphagnum peat bogs. These bacteria were strictly aerobic, Gram-negative, colourless, non-motile coccoids or short rods that multiplied by normal cell division and formed irregularly shaped cell aggregates. Strains MPL3T, MPL1011 and MOB76 were acidotolerant, mesophilic organisms capable of growth at pH 4.5-7.2 and between 4 and 33 degrees C (optimum growth at pH 5.5-6.5 and 22-28 degrees C). The preferred growth substrates were sugars, some heteropolysaccharides and galacturonic and glucuronic acids, which are released during decomposition of Sphagnum moss. The major fatty acids were ISo-C15:0, C16:0 and summed feature 3 (iso-C15:0 2-OH and/or C16:1 omega 7c); the major quinones were MK-9 and MK-10. The DNA G+C content was 55.5-56.5 mol%. Strains MPL3T, MPL1011 and MOB76 possessed nearly identical 16S rRNA gene sequences and belonged to the phylum Acidobacteria. They represent the first taxonomically characterized members of acidobacterial subdivision 3 and display only 81.7-86.7% 16S rRNA gene sequence similarity to other members of the Acidobacteria with validly published names. Therefore, strains MPL3T, MPL1011 and MOB76 are classified as representatives of a novel species in a new genus, for which the name Bryobacter aggregatus gen. nov., sp. nov. is proposed; strain MPL3T (=ATCC BAA-1390T=DSM 18758T) is the type strain of Bryobacter aggregatus.
