The DeLey-Doudoroff Pathway of Galactose Metabolism in Azotobacter vinelandii.
Azotobacter vinelandii cell extracts reduced NAD and oxidized d-galactose to galactonate that subsequently was converted to 2-keto-3-deoxy-galactonate. Further metabolism of 2-keto-3-deoxy-galactonate required the presence of ATP and resulted in the formation of pyruvate and glyceraldehyde 3-P. Radiorespirometry indicated a preferential release of CO(2) at the first carbon position of the d-gal...
متن کاملDistribution of alginate gene sequences in the Pseudomonas rRNA homology group I-Azomonas-Azotobacter lineage of superfamily B procaryotes.
Chromosomal DNA from group I Pseudomonas species, Azotobacter vinelandii, Azomonas macrocytogens, Xanthomonas campestris, Serpens flexibilis, and three enteric bacteria was screened for sequences homologous to four Pseudomonas aeruginosa alginate (alg) genes (algA, pmm, algD, and algR1). All the group I Pseudomonas species tested (including alginate producers and nonproducers) contained sequenc...
متن کاملHeavy Metal Concentration from Shrimp Culture Ponds at Point Calimer Area
Palk strait estuarine water was highly polluted by Cu, Fe, Pb, Zn and Hg. The study was carryout the interactions between heavy metals and microorganisms. The study area paying attention on the role of probiotic bacteria such as Bacillus cereus, Aeromonas hydrophila, Pseudomonas aeruginosa, Azotobacter vinelandii, and Lactobacillus sp. to remove the metals from polluted nine aquaculture ponds t...
متن کاملRole of Azotobacter vinelandii mucA and mucC gene products in alginate production.
Azotobacter vinelandii produces the exopolysaccharide alginate, which is essential for its differentiation to desiccation-resistant cysts. In different bacterial species, the alternative sigma factor sigma(E) regulates the expression of functions related to the extracytoplasmic compartments. In A. vinelandii and Pseudomonas aeruginosa, the sigma(E) factor (AlgU) is essential for alginate produc...
متن کاملThe Azotobacter vinelandii gene algJ encodes an outer-membrane protein presumably involved in export of alginate.
The algJ gene from Azotobacter vinelandii was cloned using a labelled RNA probe representing the coding region of the algE gene from Pseudomonas aeruginosa. DNA sequencing revealed an ORF of 1452 bp encoding a protein of 484 amino acid residues with a calculated molecular mass of 54611 Da. An RNA probe corresponding to algE was also used for Southern hybridization of chromosomal DNA, which show...
