Complete genome sequence of the marine, chemolithoautotrophic, ammonia-oxidizing bacterium Nitrosococcus oceani ATCC 19707

Article Abstract:

Nitrosococcus oceani (ATCC 19707) is one of only two known ammonia-oxidizing bacteria classified as Gammaproteobacteria, while the large majority of isolated ammonia-oxidizing bacteria are classified as Betaproteobacteria. The N. oceani genome contains genes for 13 complete two-component systems, all the genes needed to reconstruct complete central pathways, the tricarboxylic acid cycle, and the Emblem-Mcycrhof-Parnass and pentose phosphate pathways.

Genome of the epsilonproteobacterial chemolithoautotroph Sulfurimonas denitrificans

Article Abstract:

The genome of Sulfurimonas denitrificans DSM1251 is sequenced in order to understand the ecology and roles of sulfur-oxidizing epsilonproteobacteria, particularly those of the widespread genus Sulfurimonas. Many resistance-nodulation-development family transporter genes are described and several are predicted to encode heavy metal efflux transporters.

Urease-encoding genes in ammonia-oxidizing bacteria

Article Abstract:

The urease-encoding genes in cultured ammonia-oxidizing bacteria (AOB) from Nitrosospira, Nitrosomonas, and Nitrosococcus genera are studied. Ureolytic physiological function can be linked to the community structure of the soil AOB using the assessment of the diversity of ure genes in cultured AOB.
