The Enterococcaceae are a family of Gram-positive bacteria placed in the order Lactobacillales. [1] Representative genera include Enterococcus, Melissococcus, Pilibacter, Tetragenococcus, and Vagococcus. In this family are some important lactic acid bacteria which produce lactic acid as the major metabolic end product. [1]
Enterococcus is a large genus of lactic acid bacteria of the phylum Bacillota.Enterococci are Gram-positive cocci that often occur in pairs or short chains, and are difficult to distinguish from streptococci on physical characteristics alone. [2]
Enterococcus faecalis – formerly classified as part of the group D Streptococcus system – is a Gram-positive, commensal bacterium inhabiting the gastrointestinal tracts of humans.
Melissococcus is a genus of Gram-positive, catalase-negative, coccus-shaped lactic acid bacteria within the family Enterococcaceae. Melissococcus species were classified as Streptococcus until 1983 when Melissococcus was recognized as a distinct genus. [3]
Enterococcus gallinarum is a species of Enterococcus. [3] E. gallinarum demonstrates an inherent, low-level resistance to vancomycin.Resistance is due to a chromosomal gene, vanC, which encodes for a terminal D-alanine-D-serine instead of the usual D-alanine-D-alanine in cell wall peptidoglycan precursor proteins.

Enterococcus casseliflavus are facultative Gram-positive cocci. They are catalase negative and produce pyrolidonyl arylamidase. They are able to produce acid from many sugars, including L-Arabinose, gluconate, inulin, mannitol, melibiose, trehatol, and xylitol. [2]

Enterococcus malodoratus is a nonmotile, facultatively anaerobic microbe, as well as a chemoorganotroph with fermentative metabolism. [1] [3] The cells are coccoid in structure, found mostly in pairs or short streptococcus chains.
