Streptococcaceae are a family of Gram-positive bacteria, placed within the order Lactobacillales. [1] Representative genera include Lactococcus, Lactovum, and Streptococcus.
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).

28 The Family Streptococcaceae. Stephen Lory. Department of Microbiology and Immunobiology, Harvard Medical School, Boston, MA, USA. Abstract. This chapter discusses briefly the family Streptococcaceae and its three genera Streptococcus, Lactococcus, and Lactovum.
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.
