Biochemical characteristics and phylogenetic analysis of selected L. mesenteroides bacteria. (A) Gram positive stains showed the bacteria had purple-violet appearance and formed spherical or cocci-shaped cells. Bar = 10 μm. (B) Bubbles (arrow) leading from production of oxygen gas from S. epidermidis ATCC12228, a catalase positive bacterium, not but from identified L. mesenteroides (LM), a catalase negative bacterium. Bars = 0.5 cm. (C) A phylogenetic tree was constructed using the 16 S rRNA gene sequences from identified L. mesenteroides(LM), four L. mesenteroides strains (ATCC8293T, SJRP174, TA and 213M0) and two L. lactis strains (MBFCND-13 and KCTC3528). Bootstrap values based on 1,000 replications were indicated at branch nodes. The branch length, representing the amount of evolutionary change or genetic divergence, was shown
