Xanthomonas campestris

Xanthomonas campestris is a type of bacteria that infects plants, especially vegetables like cabbage and broccoli. It causes a disease called black rot, leading to blackening and rotting of the plant’s tissues. This bacterium spreads through contaminated water, tools, and infected plant material. It can significantly reduce crop yields and quality. Interestingly, extracts from Xanthomonas campestris are used in industry to produce a natural thickening agent called xanthan gum, used in foods, cosmetics, and other products. Overall, while it’s a plant pathogen, it also plays a role in industrial applications.
