Description and Significance
Gram-negative, non-motile coccoids 0.6-0.8 micrometers in diameter. Describe the appearance, habitat, etc. of the organism, and why you think it is important.
Genome Structure
the nifH gene was not detected with PCR analysis. Also, the mmoX gene was not detected by PCR using the respective primer set that is universal for the known mmoX genes of methanotrophs. Describe the size and content of the genome. How many chromosomes? Circular or linear? Other interesting features? What is known about its sequence?
Cell Structure, Metabolism and Life Cycle
Interesting features of cell structure; how it gains energy; what important molecules it produces.
Ecology
Japanese Hot Spring; Require methane or methanol as a carbon source to growth. Can use nitrate, ammonia, urea, tryptophan,
lysine, glutamate, formamide and Triss as nitrogen sources, but no growth was obsevered without one of these sources. symbiosis; biogeochemical significance; contributions to environment.
