Abstract excerpt
The study of the biosynthesis of alginate, the exopolysaccharide produced by Azotobacter vinelandii and Pseudomonas aeruginosa, has biotechnological and medical significance. We report here the identification of the A. vinelandii genes coding for the putative sigma factor AlgU and its negative regulators MucA and MucB through the suppression of the highly mucoid phenotype of an A. vinelandii strain by a plasmid...
