Description and Significance

Describe the appearance, habitat, etc. of the organism, and why you think it is important.

Genome Structure

Chryseobacterium Nematophagum is a bacillus that is oxidase-positive, flexirubin-pigmented, gram-negative rods that exhibit gelatinase activity. The genomes of JUb129 and JUb275 were predicted to encode 3738 and 3586 protein sequences. Grows optimally at 30 degrees Celsius on an agar plus 5% sheep's blood or a tryptone soy agar plus 5% sheep's blood. 

Cell Structure, Metabolism and Life Cycle

Chryseobacterium nematophagous kills the environmental stages of a wide range of nematode parasites. After ingested by a nematode they attack it from the inside by breaking down its extracellular matrics and then kill it.
