Query: NC_013853:1295000 Streptococcus mitis B6, complete genome
Lineage: Streptococcus mitis; Streptococcus; Streptococcaceae; Lactobacillales; Firmicutes; Bacteria
General Information: This strain was isolated from a hospital in Bochum, Germany. Streptococcus mitis. This organism is a commensal normally found in the human mouth, throat and nasopharynx. It is not usually pathogenic but can be recovered from ulcerated teeth, sinuses and blood or heart lesions from subacute endocarditis (inflammation of the membrane lining the heart) patients. Streptococci are Gram-positive, nonmotile, nonsporeforming, catalase-negative cocci that occur in pairs or chains. Members of this genus vary widely in pathogenic potential. Most streptococci are facultative anaerobes, and some are obligate anaerobes.
Subject: NC_008528:610070 Oenococcus oeni PSU-1, complete genome
Lineage: Oenococcus oeni; Oenococcus; Leuconostocaceae; Lactobacillales; Firmicutes; Bacteria
General Information: This strain was isolated at Penn State University, USA and is used commercially for malolactic fermentation in wines. Lactic acid bacterium used in wine production. Oenococcus oeni is another member of the lactic acid bacteria and it occurs naturally in marshes and similar environments. It carries out malolactic conversion during secondary fermentation in wine production which is the conversion of malic acid to lactic acid with a concomitant rise in pH, making the wine microbiologically stable and enhancing the sensory properties of the wine (aroma, flavor, and texture). The organism's high tolerance to sulfite and ethanol mean that it will be the predominant organism in the wine at the end of fermentation where it cleans up the remaining sugars and converts the bitter-tasting malic acid.
