  1. The lactic acid bacteria (LAB) are either rod-shaped ( bacilli ), or spherical ( cocci ), and are characterized by an increased tolerance to acidity (low pH range). This aspect helps LAB to outcompete other bacteria in a natural fermentation, as they can withstand the increased acidity from organic acid production (e.g., lactic acid ).
