Streptococcaceae are a family of Gram-positive bacteria, placed within the order Lactobacillales. [1] Representative genera include Lactococcus, Lactovum, and Streptococcus .
Introduction. The family Streptococcaceae include Gram-positive spherical bacteria growing in chains or pairs. They are typically non-motile, non-spore forming facultative anaerobes and oxidase negative. They attack carbohydrates fermentatively and are catalase negative.
Streptococcus is a genus of gram-positive coccus (pl.: cocci) or spherical bacteria that belongs to the family Streptococcaceae, within the order Lactobacillales (lactic acid bacteria), in the phylum Bacillota.

Streptococci are Gram-positive, nonmotile, nonsporeforming, catalase-negative cocci that occur in pairs or chains. Older cultures may lose their Gram-positive character. Most streptococci are facultative anaerobes, and some are obligate (strict) anaerobes. Most require enriched media (blood agar).
Mar 12, 2014 · Here, we utilize 46 Streptococcus genome sequences (44 species), including eight species sequenced here, to provide the first genomic level insight into the evolutionary history and genetic basis underlying the functional diversity of all major groups of this genus.
