Nitrite-oxidizing bacteria (NOB) are responsible for the second step of nitrification in natural and engineered ecosystems. The recently discovered genus Nitrotoga belongs to the Betaproteobacteria and potentially has high environmental importance. Although environmental clones affiliated with Nitrotoga are widely distributed, the limited number of(More)
To see whether plasmid molecules in bacteria are equally partitioned or randomly distributed at cell division, the segregation properties of temperature sensitive replication mutants of the E. coli plasmid pSC101 were tested at non-permissive temperature. The results support the idea that at least unreplicated molecules are passively distributed and thus(More)
