Acid Tolerance of Leuconostoc mesenteroides and Lactobacillus plantarum.
In this study, we determined the internal cellular pH response of Leuconostoc mesenteroides and Lactobacillus plantarum to the external pH created by the microorganisms themselves or by lactic or acetic acids and their salts added to the growth medium. Growth of Leuconostoc mesenteroides stopped when its internal pH reached 5.4 to 5.7, and growth of L. plantarum stopped when its internal pH rea...
متن کاملSurvival of freeze-dried leuconostoc mesenteroides and Lactobacillus plantarum related to their cellular fatty acids composition during storage.
Lactic acid bacteria strains Lactobacillus plantarum CWBI-B534 and Leuconostoc ssp. mesenteroïdes (L. mesenteroïdes) Kenya MRog2 were produced in bioreactor, concentrated, with or without cryoprotectants. In general, viable population did not change significantly after freeze-drying (p > 0.05). In most cases, viable population for cells added with cryoprotectants was significantly lower than th...
متن کاملLong-term adaptive evolution of Leuconostoc mesenteroides for enhancement of lactic acid tolerance and production
BACKGROUND Lactic acid has been approved by the United States Food and Drug Administration as Generally Regarded As Safe (GRAS) and is commonly used in the cosmetics, pharmaceutical, and food industries. Applications of lactic acid have also emerged in the plastics industry. Lactic acid bacteria (LAB), such as Leuconostoc and Lactobacillus, are widely used as lactic acid producers for food-rela...
متن کاملLeuconostoc mesenteroides Growth Kinetics
Bacterial profile modification (BPM) is being developed as an oil recovery technique that uses bacteria to selectively plug oil depleted zones within a reservoir to divert displacing fluids (typically water) into oilrich zones. Leuconostoc mesenteroides, which produces dextran when supplied with sucrose, is a bacterium that is technically feasible for use in profile modification. However, the t...
متن کاملSerological studies on Leuconostoc mesenteroides.
Following the recognition of four primary colonial types of Leuconostoc mewnteroies by McCleskey et al. (1947), Leiva-Quiros and McCleskey (1947) studied the serological relationships among strains of the four types. They employed glucose-grown cultures for the production of antibodies so the cell antigens could be studied without the complication introduced by the dextran hapten. Several worke...
