This particular bacteria is a Tegetincola.

Description and significance

Nonlabens Tegetincola is an Orange-pigmented, Gram-negative, rod-shaped and is can survive and grow in the presence of oxygen. This bacteria was discovered in the Bahamas on a microbial mat in an Estuary. The colonies that were grown on marine agar grew to the size of 2.0mm-4.0mm, and to achieve this size using the temperature of 28–36 °C. Nonlabens Tegetincola predominant fatty acids are i15 : 0, i16 : 0, i17 : 0 3-OH, and summed feature 3, comprising i15 : 0 2-OH and/or 16 : 1ω7c.

Resistance to Antibiotics

There are very few antibiotics that can kill Nonlabens Tegetincola and inhibit its growth but the ones that can are ampicillin, chloramphenicol, penicillin, streptomycin and tetracycline. Then there is a particular antibiotic that it is resistant to Kanamycin.

Test Results

Using a large scale of test results it was determined that this bacteria produces acetone, but does not produce indole or H2S. It cannot reduce Nitrate but it can hydrolyze DNA, gelatin, starch and Tweens 20, 40 and 80, but not agar, casein, cellulose or chitin.Acid phosphatase, alkaline phosphatase, α-chymotrypsin, cystine arylamidase, leucine arylamidase, valine arylamidase, esterase (C4), esterase lipase (C8), lipase (C14), trypsin and naphthol-AS-BI-phosphohydrolase activities are positive. N-acetyl-β-glucosaminidase, arginine dihydrolase, α-fucosidase, α-galactosidase, β-galactosidase, α-glucosidase, β-glucosidase, β-glucuronidase, α-mannosidase, lysine decarboxylase, ornithine decarboxylase, tryptophan deaminase and urease activities are negative. These results can be used to later help us determine if this is a bacteria that we are dealing with.

Distinct Characteristics

Nonlabens Tegetincola like most other bacteria prefers to be around the 30 °C temperature when growing to its maximum potential. One very interesting thing is the color of this bacteria, it is orange-pigmented and not very close in color to many other bacteria. This orange color makes me think about the Serratia Marcescens and how the color of this human pathogen is extremely orange like Nonlabens Tegetincola. Other than the color similarity of these two there isn't anything else in common. There is another species with the same pigmentation but was very recently discovered in the past year. Nonlabens Antarcticus is very similar when it comes to the pigments and just like Tegetincola it is strictly aerobic. Nonlaben Antarcticus grows and thrives in colder temperatures unlike Nonlabens Tegetincola which grows in a more tropical climate, Antarcticus was find in a glacier core located on King George Island in Antarctica, hence the name.

Location of Discovery

Nonlabens Tegetincola was found in an estuary which was located on a microbial mat which was found the Bahama's. Knowing about the Bahama's and the climate as well as the environment I understand why this bacteria was able to survive and flourish here. The water temperature was not too hot so it would not inhibit the growth but it was also fairly warm so it never got to cold to the point where it could thrive.

Nonlabens Tegetincola is strictly an Aerobic bacteria and with that knowledge it shows you that the Bahama's would be perfect for helping it grow big enough for us to discover it. Using the oxygen that is produced by the tropical trees and the cool breeze it is not wonder it was able to grow here. The constant climate in the Bahamas is mostly maintained at a temperature that is viable for Nonlaben Tegetincola.

Current Research

Very recent research used in finding out what is prefered by Nonlabens Tegetincola and it was tested to determine whether there was a requirement for NaCl and the medium that was used for the test was 5 g MgCl2, 2 g MgSO4, 0·5 g CaCl2, 1 g KCl, 5 g peptone and various amounts of NaCl, adjusted to pH 7·5 using KOH. Another test that helped with furthering out knowledge of Nonlabens Tegetincola is way they determined if it was motile or not. It was determined by phase-contrast light microscopy that it is a non-motile bacteria.

Other research that is being done is incubating the bacteria to find out what it requires to fully flourish and to provide us with results. There have been a few reported results of trying new agar to see the growing difference and if there is a preference for Nonlabens Tegetincola. They used Marine agar in the tests and it was observed that it yielded good results, not only revealing what temperature it prefers but the size and the type of bacteria that it is.
