Genetic identification of chemotactic transducers for amino acids in Pseudomonas aeruginosa

Article Abstract:

A research on pctB and pctC chemotactic transducer genes was conducted to determine their characteristics. Cloning and sequencing were the primary methodology used through subjecting the genes under bacterial strains and DNA manipulation. Findings showed that there were P. aeruginosa genes encoding proteins homologous to PctA in the 2.8 kb HindIII-SalI and 4.3 kb Xbal-SalI regions and that the pctB and pctC encode polypeptides with masses of 68.1 kDa and 68.4 kDa, consecutively. Furthermore, the pctABC system is included in the chemotaxis of amino acid catabolites.

Isolation of a unique benzothiophene-desulphurizing bacterium, Gordona sp. strain 213E (NCIMB 40816), and characterization of the desulphurization pathway

Article Abstract:

The isolation and characterization of Gordona sp. strain 213E is described. It is able to desulphurize benzothiophene (BTH) and has a complementary role in fuel desulphurization to that of DBT-desulphurizing isolates. Basic growth properties of strain 213E on BTH are considered, and experiments indicated that strains IGTS8 and 213E respectively express DBT and BTH-specific desulpherizing enzyme systems.
