Influence of oxidation states on iron binding by Bacillus licheniformis capsule
Article Abstract:
The effect of the oxidation states on iron binding by the gamma-glutamyl capsule polymer of Bacillus lichensis was discussed. The methodlogy involved anaerobic suspension of lyophilized capsule in ferric acid solution and addition of reducing agent. The solutions were incubated for one week, unbound metal were removed by dialysis and then prepared for trace metal anaylis. Results showed that less Fe2+ was bound than Fe3+. In addition, Fe3+ bound to the anionic bacterial polymers can released by reduction.

Application of a pH-sensitive fluoroprobe (C-SNARF -4) for pH microenvironment analysis in Pseudomonas aeruginosa biofilms
Article Abstract:
The use of seminaphthor-hodafluor-4F 5-(and-6) carboxylic acid (C-SNARF-4) for pH microenvironment analysis in Pseudomonas aeruginosa biofilms is studied. The study suggests that C-SNARF-4 could be used as a reliable indicator of pH microenvironments, which might help elucidate their influence on the medical and geobiological roles of natural biofilms.

Chromate reduction by a pseudomonad isolated from a site contaminated with chromated copper arsenate
Article Abstract:
Researchers describe a pseudomonad from a decommissioned wood preservation site that can reduce chromate Cr(VI) to Cr(III). The reaction can run aerobically and anaerobically and is catalyzed by an enzyme in the soluble portion of the cell.
