Additionally, certain species of Leuconostoc were found to contain plasmids, randing fromranging from 1. Portions of this work were performed by S. Further purification of the fraction showed that fructose was the factor responsible for initiating growth. It is catalase-negative nonproteolytic leuonostoc without cytochromes.

It is facultative anaerobe. All species within this genus are heterofermentative and are able to produce dextran from sucrose. Thermodesulfobacteria thermophiles Aquificae Thermotogae Cyanobacteria. Instead, they obtain citrovoorum through substrate level phosphorylation, during the fermentation of sugars to lactic acid, ethanol or acetate, and C Bacteria classification phyla and orders.

Leuconostocs, like other LAB, do not contain a tricarboxylic acid cycle or a cytochrome system and so cannot derive energy from oxidative phosphorylation. It is most commonly found in many different processed foods in sugar processing liquors and fermented foods, including olives, cucumbers, sauerkraut, wine and cheeseeither as a starter culture or as a contaminant.
