Lactic acid bacteria - Wikipedia
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).
12-1 An introduction to lactic acid bacteria - University of …
Lactic acid bacteria are Gram-positive usually non-motile, non-spore-forming rods and cocci. They lack the ability to synthesize cytochromes and porphyrins (components of respiratory chains) and therefore cannot generate ATP by creation of a proton gradient.
Lactic-acid bacterium | Fermentation, Probiotics, Metabolism
Lactic-acid bacterium, any member of several genera of gram-positive, rod- or sphere-shaped bacteria that produce lactic acid as the principal or sole end product of carbohydrate fermentation. Lactic-acid bacteria are aerotolerant anaerobes that …

2017年11月3日 · Lactic acid bacteria are characterized by the production of lactic acid as a major catabolic end product from glucose. Some bacilli, such as Actinomyces israeli and bifidobacteria, can form lactic acid as a major end product, but these bacteria have rarely or never been isolated from must and wine.

Lactic acid bacteria (LAB) stand out as a group of versatile and fascinating microorganisms. Known for their remarkable contributions to producing fermented foods and beverages, humans have used these bacteria for centuries.
Lactic Acid Bacterium - an overview | ScienceDirect Topics
Lactic acid bacteria are a class of Gram-positive, non-spore-forming, non-reactive but gas-tolerant microorganisms. They are usually characterized by their ability to produce lactic acid. Lactic acid bacteria, as an indispensable fermentation bacterium, are considered a kind of probiotic.
Diversity and Functional Properties of Lactic Acid Bacteria …
2019年5月20日 · Lactic acid bacteria (LAB) are capable of converting carbohydrate substrates into organic acids (mainly lactic acid) and producing a wide range of metabolites. Due to their interesting beneficial properties, LAB are widely used as starter cultures, as probiotics, and as microbial cell factories.
