Xylella fastidiosa, a pathogen of citrus, is the first plant pathogenic bacterium for which the complete genome sequence has been published. Inspection of the sequence reveals high relatedness to many genes of other pathogens, notably Xanthomonas campestris. Based on this, we suggest that Xylella possesses certain easily testable properties that contribute to pathogenicity. We also present some...

Due to the emergence of bacterial resistance in phytopathogenic microorganisms, it is necessary search for new treatment alternatives these pathogens. Natural extracts are a potential source bioactive compounds that can act against such strains. The antibacterial activity Larrea tridentata bacteria with public health importance has been documented; however, few reports cover pathogens associate...

Xanthan biopolymer has been produced by single-stage continuous ferment~ tion with Xanthomonas campestris NRRL B-1459 in a medium of glucose, minerals, distillers' solubles, and urea for as long as 20 days. At the highest dilution rate studied (D = 0.0285 hr-1), the steady state rate of xanthan production was 0.36 g/kg/hr and ·the steady state yield, basis glucose consumed, was 68%. Observation...

A variety of lactic acid bacteria, isolated from plant surfaces and plant-associated products, were found to be antagonistic to test strains of the phytopathogens Xanthomonas campestris, Erwinia carotovora, and Pseudomonas syringae. Effective "in vitro" inhibition was found both on agar plates and in broth cultures. In pot trials, treatment of bean plants with a Lactobacillus plantarum strain b...
