Caldivirga maquilingensis
Description and Significance
Describe the appearance, habitat, etc. of the organism, and why you think it is important. Caldivirga maquilingensis is a rod shaped heterotrophic crenarchaeote that is found in the anaerobic or microaerobic environments of the mud springs of the Phillipines. It is a hyperthermophile that grows optimally around 85 degrees celsius as well as in acidic environments within the pH range of 2.3 to 6.4.
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.
