Acetobacter senegalensis
Species of bacteria
From Wikipedia, the free encyclopedia
Acetobacter senegalensis is a species of Alphaproteobacteria known for its tendency to live in certain fruit species and its potential in bacterial cellulose and vinegar production.

Discovery
Growth and morphology
Acetobacter senegalensis is gram-negative, catalase-positive, oxidase-negative, and a strict aerobe.[1] It is coccoid in shape, and measures roughly 1.2-2.0 μm in length and 0.8 μm in width. Growth has been observed between 28-40°C, with optimal growth occurring around 35°C. When grown on agar plates containing yeast extract, D-mannitol, and peptone, colonies are visible within 24 hours of incubation at 28°C, and appear circular, convex, and beige in color.[1] A. senegalensis is capable of using glycerol as a sole carbon source; however, it cannot use maltose or methanol. Its inability to utilize methanol can be used to differentiate it from one of its closest relatives, Acetobacter tropicalis.[1] It has the ability to produce acetic acid; however, acetic acid has been shown to damage A. senegalensis cells at a concentration of 1% w/v.[3]
Industrial utility
Acetobacter senegalensis, like other Acetobacter species, has the ability to produce vinegar. Due to its thermotolerant nature, it has been proposed as a useful species in the industrial production of vinegar in areas of the world that may be too hot for other acetic acid bacteria.[1][4]
Acetobacter senegalensis is also known as a potential starter culture species in the cocoa bean fermentation process, although it may be outcompeted by its relative Acetobacter pasteurianus.[5]
In addition, A. senegalensis has also been investigated for its ability to synthesize bacterial cellulose.[6]
