Based on the laboratory tests provided, it can be determined that the unknown organism can be identified as Pseudomonas aeruginosa (P. aeruginosa). This organism is an opportunistic pathogen that can infect non-mammalian, plants, and humans. P. aeruginosa belongs to the bacterial family Pseudomonadaceae, and is a gram-negative rod that approximately measures 0.5 to 0.8 µm by 1.5 to 3.0 µm. It can normally be found in water and soil. Its single polar flagellum makes it motile, and it is known to be one of the fastest swimming bacteria found in hay infusion and pond water (Crittenden, Trussell, Hand, and Howe 2012).
Due the extensive size of the genome, 6.3 million base pairs, P. aeruginosa is capable of adapting to a wide variety of environments (Descamps, Sallenave, and Manoury 2012). As a free-swimming cell, it can live as a sessile biofilm as well as in planktonic form (Crittenden et al. 2012). It has minimal nutritional needs and does not require organic growth factors, but for growth, it can use more than thirty organic compounds. The optimal growth temperature for this organism is thirty-seven degrees. However, it is capable of growth with temperatures as high as forty-two degrees And as indicated by the laboratory results, this organism is able to grow even if O2 is not present, as long as NO3 is available.
The organism’s capacity to adapt to a wide variety of environments is a threat to non-mammalian, plants, and humans. A common nosocomial pathogen that poses a…
