Xanthomonas

campestris Xanthomonas campestris is a species of Gram-negative bacteria that is found in agricultural environments, particularly in the soil. X. campestris is significant because it is capable of causing diseases, such as black rot, in a variety of plants, including crucifers, cotton, peanuts, and various vegetables. In addition, X. campestris has several uses in research, such as studying the effects of environmental and chemical agents on bacteria. X. campestris has also been used for bioremediation – the process of removing pollutants and toxins from the environment – as well as for bioproduction in the manufacture of biofuels and other products.
