Characteristics

Cells appear as Gram-positive cocci occurring singly, in pairs or short chains. The organism grows under both aerobic and anaerobic conditions and is catalase-negative. Phylogenetic analysis of the 16S rRNA gene shows ≤ 96.6 % sequence similarity to its closest relative, Aerococcus suis, confirming its novel status.^[1] The specific epithet kribbianus honours the Korea Research Institute of Bioscience and Biotechnology (KRIBB).^[2]
