Natronococcus is a genus of archaeans in the family the Natrialbaceae. [1]
This haloalkaliphilic archaeon is in the same family as microorganisms like Halobacterium . Study of Natronococcus continues to explore what enzymes are present in order to survive in these conditions, especially since there has not been much literature about enzymes of haloalkaliphiles.
The G + C content for the major chromosome is 64.0% while the minor component has a 55.7% content. The approximate size of the plasmid is 144 kbp.
Natronococcus is a heterotrophic, aerobic organism that can use sugars as an energy source to stimulate growth. It can fix nitrogen from casamino acids and reduces nitrates to nitrites.
Cells are non-motile and occur in irregular clusters, pairs, and single cells. The cell is coccoid in shape and 1–2 micrometres in diameter. colonies are pale brown and circular. [2]
N. occultus has been isolated from the soda lake Lake Magadi. This halophilic archaeon is partial to environments with 8–30% NaCl with optimum growth at 22%. It also grows in a pH range of 8.5–11 (optimum at 9.5) and a temperature range of 20–50 °C (optimum at 40 °C).
The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) [3] and National Center for Biotechnology Information (NCBI). [1]
