Xanthomonas spp. is a phytopathogen responsible for causing necrotic lesions on the edges of the plant leaves. It infects various susceptible plant species such as cruciferous vegetables. Xanthomonas has the capability to produce an exopolysaccharide called Xanthan. When Xanthomonas spp. is inoculated in a suitable fermentation media it produces xanthan. Xanthan is used as a natural polymer for various industrial purposes, where it is used as a stabilizer, emulsifier and thickening agent. The research was conducted to selectively isolate Xanthomonas spp. from necrotic lesions of spoiled leafy vegetables like cabbage & cauliflower and to produce xanthan. The xanthanwas characterized by various chemicals tests such as Molisch test, Anthrone test, osazone test. The antioxidant capacity of the extracted xanthan was also done using DPPH assay. Xanthomonadin is a yellow coloured pigment which is selectively produced by Xanthomonas spp. The Xanthomonadin was extracted from the isolated Xanthomonas spp. and its characterization was carried out by absorption spectrum respectively.
