Lactic Acid Bacteria - an overview | ScienceDirect Topics
Lactic acid bacteria (LAB) are a heterogeneous group of phylogenetically closely related microorganisms that produce lactic acid as the major or sole product of carbohydrate fermentation. LAB are Gram positive, nonsporulating, catalase-negative, acid tolerant, nonrespiring but aerotolerant, usually nonmotile cocci or rods with low Guanidine ...
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.
Metabolism Characteristics of Lactic Acid Bacteria and the …
2021年5月11日 · Lactic acid bacteria (LAB) are a type of gram-positive bacteria that use carbohydrates as the only or main carbon source (George et al., 2018). Lactic acid bacteria are generally cocci or rods, and have strong tolerance to low pH.
Isolation and Identification of Lactic Acid Bacteria
2023年9月30日 · LABs are Gram-positive, non-spore-forming rods, cocci, and coccobacilli, non-respiring but aero-tolerant, fastidious, acid-tolerant and catalase-negative devoid of cytochromes. This group produces lactic acid as one of the key fermentation products by utilizing carbohydrates during fermentation.
Recent developments of lactic acid bacteria and their metabolites …
2022年6月1日 · Lactic acid bacteria (LAB) are common microorganisms found in various ecosystems including in plants, fermented foods, and the human body. Exploring the biodiversity of lactic acid microflora and characterization of LAB is a new approach to form a variety of starter communities to create innovative nutritional food matrices.
Lactic acid bacteria: an essential probiotic and starter culture for ...
2022年9月7日 · In this review, we discuss the importance of LAB as starter cultures and a probiotic for yoghurt production, its mode of metabolism, acidification characteristic, synthesis of lactase (β-galactosidase) and a perspective on LAB's growth medium for dairy fermentations.
Editorial: Lactic Acid Bacteria: Microbial Metabolism and …
2021年11月12日 · Lactic acid bacteria (LAB) are a group of lactic acid-forming bacteria that are generally recognized as safe (GRAS), facultatively anaerobic, non-respiring and non-sporulating. They are ubiquitous in nature, present from plant materials, milk and meat to …
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.
