Classification
Genus species Pseudomonas lini Scientific classification Kingdom: Bacteria
Phylum: Proteobacteria
Class: Gamma Proteobacteria
Order: Pseudomonadales
Family: Pseudomonadaceae
Species
Genus: Pseudomonas
Species: Pseudomonas Fluorescens
Habitat Information
Date of collection: 1/27/15
Location: 6636 W. William cannon Dr. Austin, TX 78735
Lat/:on: 30.27N 97.74W (Elev. 508ft)
Air Temperature: 80 degrees F
Humidity: 23%
24 hr rainfall: 0
Solar Radiation: 12.84
Description and Significance
Colonial Morphology:
Color:white
Elevation:Convex
Margin:Smooth
Cell Morphology:
Members of the genus display these defining characteristics:
* Rod-shaped
* Gram-negative
*One or more polar flagella, providing motility
* Aerobic
* Nonspore-forming
Test Results
* Negative catalase test (this result is questionable) * Negative oxidase test (this result is questionable)
* Positive EMB for G- growth * Positive EMB for lactose fermentation * Positive MAC for G- growth * Positive HE for G- growth * Positive arganine decarboxylation test * Positive Blood Agar test * Positive Urea test * VP test was questionable
Antimicrobial activity :
Most Psuedomonas species are penicillin resistant, so other choices for treatment might include Ciprofloxacin, ticarcillin, imipenem or piperacillin. This resistance is due to their cell walls which contain prions. [1]
My Results Ceftazidine proved very effective Clove and tea tree oil very effective
Genome Structure
Pseudomonas fluorescens Strain DH-27 16S Ribosomal
Long Circular chromosome
Max score: 1291 Total score: 1291 Query Cover: 100% E Value: 0.0 Ident: 99% Accession: KF646699.1
Cell Structure, Metabolism and Life Cycle
Pseudomonas fluorescens produces phloroglucinol, phloroglucinol carboxylic acid and diacetylphloroglucinol. Biodegradation capacities
4-Hydroxyacetophenone monooxygenase is an enzyme found in P. fluorescens that transform piceol, NADPH, H+ and O2 into 4-hydroxyphenyl acetate, NADP+ and H2O.
Physiology and Pathogenesis
Pseudomonas fluorescens may be useful in protecting plants from fungus and nemotade attacks.
By culturing Pseudomonas fluorescens, Mupirocin (an antibiotic) can be produced, which has been found to be useful in treating skin, ear, and eye disorders.[19] Mupirocin free acid and its salts and esters are agents currently used in creams, ointments, and sprays as a treatment of Methicillin-resistant Staphylococcus aureus (MRSA) infection.
P. fluorescens demonstrates hemolytic activity and, as a result, has been known to infect blood transfusions.
It is also used in milk to make yogurt.
Disease:
P. fluorescens can be found infecteing those who are immunocompromised including cancer patients.[2]
Medical Properties:
Psuedomonas fluorescens has hemolytic properties and can infect blood transfusion. It can also be used as a strater for yogurts. P. fluorescens can be used to make the antibiotic Mupirocin which can be used to treati MRSA, skin, ear, and eye disorders.[2]
