Habitat Information
Latitude: 30.26 degrees Longitude: 97.69 degrees
It was a clear day with a temperature of 64 degrees in the area of Govalle, East Austin on January 25th 2018. A ziplock bag was used to collect the soil from the area mostly from the surface about one inch deep. The location of the soil sample chosen was in a neighborhood field often frequented by dogs. Rainfall was 0.0" and the pressure was 35.35". The description of the location was mostly Bergstrom soils and urban land. 0-2% slopes and rarely flooded.
Description and Significance
Describe the appearance (colonial and cellular), possible antimicrobial activity etc. of the organism, and why the organism might be significant.
The colonial characteristics of the organism are described as follows: circular, convex, and entire margins. Caramel in color with no extracelluar pigment and a shiny, mucoid appearance. To determine the extent of the antimicrobial activity of the organism, further testing would be needed as there was only some clearing when tested.
A unique characteristic of this gram-negative is its polar flagellum, although some have two polar flagella. There was no discernible arrangement of the cocci bacterium

Cell Structure, Metabolism and Life Cycle
Studies have shown that glucose was the optimum carbon source and ammonium oxalate the optimum nitrogen source of this bacterium. It is an oxidase- and catalase-positive, aerobic, with a respiratory type of metabolism with oxygen as the terminal electron acceptor. It was shown to produce (+)-γ-lactamase to hydrolyze racemic (+/−)-γ-lactam from several soil samples using (+/−)-γ-lactam as the only carbon source.
