Cell wall structure and function in lactic acid bacteria
Aug 29, 2014 · The cell wall of Gram-positive bacteria is a complex assemblage of glycopolymers and proteins. It consists of a thick peptidoglycan sacculus that surrounds the cytoplasmic membrane and that is decorated with teichoic acids, polysaccharides, and proteins.
Lactic acid bacteria - Wikipedia
These bacteria, usually found in decomposing plants and milk products, produce lactic acid as the major metabolic end product of carbohydrate fermentation, giving them the common name lactic acid bacteria (LAB).
Cell wall homeostasis in lactic acid bacteria: threats and defences
This review covers the most recent advances in the cell wall structure of lactic acid bacteria (LAB), its role as the target for bacteriocins, bacteriophages and host factors and how LAB sense and respond to cell wall damage.
Lactic Acid Bacteria - an overview | ScienceDirect Topics
The lactic acid bacteria are a group of Gram-positive bacteria, non-respiring non-spore-forming, cocci or rods, which produce lactic acid as the major end product of the fermentation of carbohydrates.
Lactic Acid Bacteria as Cell Factories | ScienceDirect
Lactic acid bacteria (LAB) are Generally Recognized as Safe (GRAS) microorganisms used as a cell factory worldwide. Gene expression in LAB can be precisely regulated, making it possible to create therapeutics to detect and control specific diseases and deliver drug molecules.
Cell wall structure and function in lactic acid bacteria
Aug 29, 2014 · Lactic acid bacteria (LAB) are Gram-positive bacteria that belong to numerous genera, including Lactococcus, Enterococcus, Oenococcus, Pediococcus, Streptococcus, and Lactobacillus [1 – 3].
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.
The Cell Wall of Lactic Acid Bacteria: Surface Constituents and ...
We have probed the surface properties of a number of strains of lactic acid bacteria using a variety of microscopic and physicochemical techniques with emphasis on the elucidation of the global physicochemical nature of the outer layer of the cell wall, the conformation of the surface macromolecules, and the susceptibility of the surface toward ...

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 Bacteria as Cell Factories for the Generation of …
This article reviews the current knowledge on LAB as cell factories for the production of bioactive peptides from a variety of food protein sources. These microorganisms depend on a complex proteolytic system to ensure successful fermentation processes.
