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). Laboratory media used for LAB typically include a carbohydrate source, as most species are incapable of respiration. LAB are catalase-negative. L… reacher serie ver online https://jbtravelers.com
