Habitat Information

Latitude: 30.14402 degrees Longitude: -97.78506 degrees

It was a cloudy day high of 58 degrees low of 44 degrees on Jan 30th 2015. A spade and a glass mason jar to collet the soil sample. The soil was collected after digging 1 foot below the surface. The location of the soil sample chosen was in a natural ravine off the end of a gated home property Rainfall was 0.0" and the pressure was 28.53" The location was mostly Lewisville silty clay at 1-2 percent slopes.

Description and Significance

Describe the appearance (colonial and cellular), possible antimicrobial activity etc. of the organism, and why the organism might be significant.

Cellular: gram negative aerobic rod shaped red pigmented

Colonial: red pigmented round convex smooth

This soil microbe was placed on a lawn of Pseudomonas Aeruginosa, which is a gram negative bacteria, and it had a zone of inhibition which indicates antimicrobial capabilities.

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.

The Genome structure Pontibacter salisaro strain HMC5104 16S ribosomal RNA gene, partial sequence. It is linear, and not much else is known about this specific bacteria as of yet.

Cell Structure, Metabolism and Life Cycle

Currently, Pontibacter Salisaro has not been observed for it's cell structure, metabolism and life cycle.

Here are the results from our lab tests.

It had a zone of inhibition against a lawn of Pseudamonas Aeruginosa

TSI: no fermentation however slight acidic

SIM: Positive for motility

Methyl Red: positive: acidic and is capable for mixed acid fermentation

Nitrate: positive change from Nitrate to Nitrite

Blood agar: alpha hemolysis which refers to partial hemolytic breakdown

PEA test: Gram negative bacteria because inhibition of growth

Bile Esculin and 6.5% salt tolerance test: tested positive for other group D enteroccoci

Physiology and Pathogenesis

Currently, Pontibacter Salisaro has not bee observed in relation to its pathogenic abilities, disinfectants and antibiotic tests were run on agar. It is resistant to oxacillian.
