Members of the ecologically versatile Lactobacillus casei, L. plantarum and L. sakei groups are apparently best equipped to deal with aerobic/respiratory growth. Activation of respiratory pathways reduces the detrimental effects of oxygen. Lactobacillus plantarum is a facultative anaerobic bacterium that is used as a model organism in studies on microbe-host interactions for identification of probiotic functions.L.

Lactobacillus plantarumis a facultative anaerobic bacterium that is used as a model organism in studies on microbe-host interactions for identification of probiotic functions. Although Lactobacillus casei is generally considered to be "indifferent" to oxygen, several strains exhibited considerable respiratory activity with a number of substrates related to carbohydrate catabolism.

Lactobacillus genomes do not harbour sequences for AR (this study) and, therefore, diacetyl may be exclusively produced by aerobic als‐driven pyruvate decarboxylation.

Lactobacillus is a genus of Gram-positive, aerotolerant anaerobes or microaerophilic, rod-shaped, non-spore-forming bacteria. The Lactobacillus delbrueckii bacteria are also facultative anaerobic, which means that they can produce ATP (adenosine triphosphate), the primary energy carrier in all living things, in both oxygenated conditions, or through fermentation or anaerobic respiration in conditions lacking oxygen. Regulation of protein abundance in the proteome of Lactobacillus casei N87 cultivated in anaerobic, aerobic and respiratory conditions (in exponential and stationary phases) and functional classification of identified proteins according to COG database. I would like to revive and culture L. acidophilus from the purchased L-dried sample. Aerobic and respiratory lyfe-styles modulate the proteome expressed by L. casei N87. In humans, they constitute a significant component of the microbiota at a number of body sites, such as the digestive system, urinary system , and genital system.

Lactic acid bacteria (LAB) are used as starter, adjunct and/or probiotic cultures in fermented foods.

International Journal of Food Microbiology, https://doi.org/10.1016/j.ijfoodmicro.2019.03.006. The pH is about 4-5 preventing the growth of other active bacterias. Although Lactobacillus casei is generally considered to be "indifferent" to oxygen, several strains exhibited considerable respiratory activity with a number of substrates related to carbohydrate catabolism. L. acidophilus grows in low pH (<3.5), anaerobic conditions and ... cytochromes, porphyrins, and respiratory enzymes and as a result are unable to undergo any oxidative phosphorylation or respiration. Lactobacillus bacteria are used to sour milk in the production of yogurt.? As I do not have anaerobic facilities, I am thinking to grow them in aerobic conditions. Several species are recognized as oxygen-tolerant anaerobes, and aerobic and respiratory cultivations may provide them with physiological and technological benefits. The shift from anaerobic growth to aerobic (oxygen) and/or respiratory promoting (oxygen, exogenous haem and menaquinone) conditions offers physiological advantages and affects the pattern of metabolite production in several species. They convert sugars/glucose to Lactic acid. They are a major part of the lactic acid bacteria group (i.e., they convert sugars to lactic acid). These authors contributed equally to the present work.

Lactobacillus plantarum is a facultative heterofermentative lactic acid bacterium used worldwide in production of fermented food and feed products, and its natural habitats are anaerobic or microaerobic.
