Lactococcus is a genus of lactic acid bacteria that were formerly included in the genus Streptococcus Group N1. They are known as homofermentors 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 cultural 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 7ËC.Nine species of Lactococcus are currently recognized along with four subspecies.hey are gram-positive, catalase-negative, non-motile cocci that are found singly, in pairs, or in chains.
