Lactococcus
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

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 chains. The genus contains strains known to grow at or below 7˚C.
Twelve species of Lactococcus are currently recognized. They are: Lactococcus allomyrinae Lactococcus carnosus Lactococcus chungangensis Lactococcus cremoris L. cremoris subsp. cremoris L. cremoris subsp. tructae Lactococcus formosensis L. formosensis subsp. bovis L. formosensis subsp. formosensis Lactococcus fujiensis Lactococcus garvieae L. garvieae subsp. garvieae L. garvieae subsp. bovis Lactococcus hircilactis Lactococcus hodotermopsidis Lactococcus insecticola Lactococcus kimchii Lactococcus lactis L. lactis subsp. hordniae L. lactis subsp. lactis Lactococcus laudensis Lactococcus nasutitermitis Lactococcus paracarnosus Lactococcus petauri Lactococcus piscium Lactococcus plantarum Lactococcus protaetiae Lactococcus raffinolactis Lactococcus reticulitermitis Lactococcus taiwanensis Lactococcus termiticola
