Involvement of Pseudomonas aeruginosa rhodanese in protection from cyanide toxicity
Article Abstract:
The presence of multiple sulfurtransferases in the cyanogenic bacterium Pseudomonas aeruginosa PAO1 is described and RhdA, a thiosulfate:cyanide sulfutransferase (rhodanese), which converts cyanide to less toxic thiocyanate, is examined. RhdA is regarded as an effector of Pseudomonas aeruginosa intrinsic resistance to cyanide, as it provides the bacterium with a defense mechanism against endogenous cyanide toxin, in addition to cyanide-resistant respiration.

Microbial community structure and dynamics of dark fire-cured tobacco fermentation
Article Abstract:
The microbial community structure and dynamics of tobacco were investigated by culture-based and culture-independent approaches, including denaturing gradient gel electrophoresis and single-strand conformational polymorphism. The results demonstrate that fermentation is assisted by a complex microbial community, changing in structure and composition during the process.

Effect of superoxide dismutase gene inactivation on virulence of Pseudomonas aeruginosa PAO1 toward the silkworm, Bombyx mori
Article Abstract:
The role of superoxide dismutase (SOD) in virulence against the silkwork, Bombyx mori explored by generating mutants of Pseudomans aeruginosa showed that full virulence of Pseudomans aeruginosa against Bombyx mori and Fe-SOD is more important than Mn-SOD in the infection process.
