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

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 aerobe is its polar flagellum, although some have two polar flagella. There was no discernible arrangement of the cocci bacterium

Genome Structure

Describe the size and content of the genome. How many chromosomes? Circular or linear? Other interesting features? What is known about its sequence? Include S Ribosomal sequence that you obtained from PCR and sequencing here.
