Streptococcaceae

Streptococcus, from Ancient Greek στρεπτός (streptós), meaning "twisted", and κόκκος (kókkos), meaning "grain", is a genus of gram-positive spherical bacteria that belongs to the family Streptococcaceae, within the order Lactobacillales (lactic acid bacteria), in the phylum Bacillota. Cell division in streptococci occurs along a single axis, thus when growing they tend to form pairs or chains, which may appear bent or twisted. This differs from staphylococci, which divide along multiple axes, thereby generating irregular, grape-like clusters of cells. Most streptococci are oxidase-negative and

Streptococcaceae, from Ancient Greek στρεπτός (streptós), meaning "twisted", and κόκκος (kókkos), meaning "grain", are a family of gram-positive bacteria, placed within the order Lactobacillales. Representative genera include Lactococcus, Lactovum, and Streptococcus.

Lactococcus, from Latin lac, meaning "milk", and Ancient Greek κόκκος (kókkos), meaning "berry", is a genus of lactic acid bacteria that were formerly included in the genus Streptococcus Group N1. They are known as homofermenters meaning that they produce a single product, lactic acid in this case, as the major or only product of glucose fermentation. Their homofermentative character can be altered by adjusting environmental conditions such as pH, glucose concentration, and nutrient limitation. They are gram-positive, catalase-negative, non-motile cocci that are found singly, in pairs, or in c
