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.

As food-grade bacteria, they are used in the production of foreign proteins that are applied to the food industry.

Lactococcosis refers to a group of disorders caused by the bacterium L. garvieae.
