Description and Significance
Describe the appearance, habitat, etc. of the organism, and why you think it is important.
Caldivirga maquilingensis were first isolated from a hot spring located in the Philippines. This hot spring is known as 'mud spring' and is found in Mt. Maquiling, Laguna. This hot spring is extremely acidic. The temperature range for the spring range from 60-92*C. The pH range was from 2.3-6.4.
In lab growth, it was determined that C. maquilingensis grew best at 85*C and at a pH range of 3.7-4.2.
The appearance of C. maquilingensis ranges slightly. Most are rod-shaped and are either completely straight or have a slight curve shape. Although, the width of the bacteria range widely, the average size is 0.4-0.7 micrometers.
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?
Cell Structure, Metabolism and Life Cycle
Interesting features of cell structure; how it gains energy; what important molecules it produces.
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.
