Citricoccus nitrophenolicus
Description and Significance
Citricoccus nitrophenolicus is a gram-posiitive, coccoid, non-motile aerobe that doesn't form endospores and metabolizes para-nitrophenol (pNP) into nitrite.
It was originally isolated from a wastewter treatment facility plant in Denmark, and by means of by means of selective enrichment using para-nitrophenol Citricoccus nitrophenolicus was isolated.
C. nitrophenolicus can grow at temperatures ranging from 15 to 32 degrees Celsius and at an optimum temperature of 27 degrees Celsius. Optimal growth was observed at a pH of 8 and ranged all the way from 6.8 to 10. C. nitrophenolicus was considered a halotolerant because of it's ability to grow at at salinity levels ranging from 3% to 17%.
When grown in the lab on agar plates, it exhibits bright yellow colonies, which are circular, convex and smooth.
Genome Structure
Describe the size and content of the genome. How many chromosomes? Circular or linear? Other interesting features? What is known about its sequence?
Metabolism and Life Cycle
heterotrophs, anaerobically and microaerobically
require sulfur, thiosulfate or sulfate as electron acceptors
isolates grew well in yeast extract (carbon source)
other sugars worked, but not as well (glycogen, gelatin, etc.)
large amounts of tetraether core lipids and trace amounts of diether core lipids.
Ecology and Pathogenesis
Habitat; symbiosis; biogeochemical significance; contributions to environment.
If relevant, how does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
