Xanthomonas campestris is commonly used industrially to produce a water-soluble exo-polysaccharide, known as xanthan gum, from fermentation of carbon sources like glucose. [5] In this process, a preserved culture of the gram-negative bacterium is expanded through growth and then used as an inoculum in bioreactors with liquid growth media .
Xanthomonas campestris (Pammel) Dowson (1939) Black rot , caused by the bacterium Xanthomonas campestris pv. campestris ( Xcc ), is considered the most important and most destructive disease of crucifers, infecting all cultivated varieties of brassicas worldwide.
Xanthomonas (from greek: xanthos – "yellow"; monas – "entity") is a genus of bacteria, many of which cause plant diseases. [1] There are at least 27 plant associated Xanthomonas spp. , that all together infect at least 400 plant species.
Xanthomonas campestris pv. vesicatoria is a large problem in greenhouses and nurseries where very high humidity and warm temperatures provide a good environment for the bacteria to grow and wet soils easily transmit the disease from plant to plant. Overcrowding in propagation facilities also increases the likelihood of spreading this disease ...
Xanthomonas axonopodis pv. malvacearum Bacterial blight of cotton is a disease affecting the cotton plant resulting from infection by Xanthomonas axonopodis pathovar malvacearum (Xcm) a Gram negative, motile rod-shaped, non spore-forming bacterium with a single polar flagellum
The causal agent is the Gram negative bacterium Xanthomonas translucens pv. graminis (syn. X. campestris pv. graminis). The first case of bacterial wilt of turf was reported in a cultivar of creeping bentgrass known as Toronto or C-15, which is found throughout the midwestern United States. Until the causal agent was identified in 1984, the ...
Xanthomonas campestris pv. juglandis is an anaerobic, Gram negative, rod-shaped bacteria that can affect walnut trees though the flowers, buds, shoots, branches, trunk, and fruit. It can have devastating effects including premature fruit drop and lesions on the plant.
Xanthomonas campestris pv. raphani is a gram-negative, obligate aerobic bacterium that like many other Xanthomonas spp. bacteria has been found associated with plants. This organism is closely related with Xanthomonas campestris pv. campestris, but causes a non-vascular leaf spot disease that is clearly distinct from black rot of brassicas.
