Rapid viability loss on exposure to air in a superoxide dismutase-deficient mutant of Porphyromonas gingivalis.

Journal of bacteriology - 1 Apr 1994

Nakayama K

Abstract excerpt

Porphyromonas gingivalis, an obligate anaerobe, exhibits a relatively high degree of aerotolerance and possesses superoxide dismutase (SOD) which is induced by exposure to air. To clarify roles for SOD in this organism, the gene encoding SOD (sod) on the P. gingivalis chromosome was disrupted in a gene-directed way by use of a suicide plasmid containing a mutated sod. A sod mutant thus obtained showed no SOD...
