Overview
Leuconostoc[1] is a genus of Gram-positive bacteria, placed within the family of Leuconostocaceae. They are generally ovoid cocci often forming chains. Leuconostoc sp. are intrinsically resistant to vancomycin and are catalase-negative (which distinguishes them from staphylococci). All species within this genus are heterofermentative and are able to produce dextran from sucrose. They are generally slime-forming.
Blamed for causing the 'stink' when creating a sourdough starter. Some species are also capable of causing human infection.[2] Because they are an uncommon cause of disease in humans, standard commercial identification kits are often unable to identify the organism[3].
