Pediococcus acidilactici is a species of Gram-positive cocci that is often found in pairs or tetrads. P. acidilactici is a homofermentative bacterium that can grow in a wide range of pH, temperature, and osmotic pressure, therefore being able to colonize the digestive tract. It has emerged as a potential probiotic that has shown promising results in animal and human experiments, though some of the results are limited. They are commonly found in fermented vegetables, fermented dairy products, and meat.

Pediococcus acidilactici is a facultative anaerobe that grows well on deMann, Rogosa, Sharpe agar of an optimum pH of 6.2, with an overnight incubation at 37 and 45°C. It is also viable at higher temperatures up to 65°C.

This species is also acidophilic, viable at very low pH. The probiotic P. acidilactici is a facultative anaerobe with lesser sensitivity to oxygen. Pediococci exert antagonism against other microorganisms, including enteric pathogens, primarily through the production of lactic acid and secretion of bacteriocins known as pediocins.
