Pseudomonas that I chose
Pseudomonas lundensis is a gram negative, rod shaped bacteria that are motile with one polar flagella that propels it forward. The optimal temperature for
P. lundensis is 25°C but its temperature range is from 0°C to 33°C. One third of
P. lundensis strains can also grow at 37°C (optimal human body temperature). The colonies on nutrient agar will be smooth, circular and lack pigment but a green tinge may sometimes be seen.
P. lundensis cannot grow at a pH of 4.5.
