Their homofermentative appearance can be adapted by adjusting cultural altitude like pH, glucose concentration, and comestible limitation. They are gram-positive, catalase-negative, non-motile cocci that are begin singly, in pairs, or in chains. The brand contains strains accepted to abound at or beneath 7?C.
These bacilli are frequently acclimated in the dairy industry in the accomplish of brewed dairy articles like cheeses. They can be acclimated in single-strain amateur cultures, or in mixed-strain cultures with added lactic acerbic bacilli such as Lactobacillus and Streptococcus. Special absorption is placed on the abstraction of L. lactis subsp. lactis and L. lactis subsp. cremoris, as they are the strains acclimated as amateur cultures in automated dairy fermentations. Their capital purpose in dairy assembly is the accelerated acidification of milk; this causes a bead in the pH of the brewed product, which prevents the advance of accident bacteria. The bacilli aswell play a role in the acidity of the final product. Lactococcus are currently getting acclimated in the biotechnology industry.
