Editor's Notes

  • #2 Abneil Good afternoon, we are group #4 We will be talking about tropical soil bacteria Isolation & Characterization You know our names We will have bacteria designator
  • #4 Anibal Both samples were moist Sample A being Urban, had a more basic pH than the rural
  • #5 Ramon Moist pH did not have a big difference
  • #6 Abneil Sample A: Was taken beside a pipeline that comes from the surgery floor Sample B: Is right beside a spout that people from the area believe that could be very contaminated
  • #7 Ann Sample C: area that will be used to build an urbanization Sample D: Surrounded by La Plata River
  • #8 Abneil This Geographic information system map recorded where each sample was collected. Sample A: was collected San Juan B: was collected in Caguas C: in Aibonito D:here in Cayey
  • #9 Anibal Regarding the GIS map we showed previously we have different bacterial designator codes, PCR & Electrophoresis gave positive
  • #10 Ramon Our antibiotic production was negative. The PCR and Electrophoresis was negative.
  • #11 Abneil Sample A & B were purified in R2A mediums instead of ISP4 because they showed better efficacy
  • #12 Ann Sample C and D were purified in ISP4 Fungus grew and the medium had to change to LB
  • #13 Anibal Sample A: Gram stain was repeated thrice Sample B: Was repeated twice and we concluded that they were both Gram Positive Homogeneous
  • #14 Ramon Sample C: Gram stain from the isolation #3 Sample D: gram stain with the purification #4 Was no Homogeneous
  • #15 Abneil The plate interpretations for Sample A & B were similar in form and Margin but different in elevation.
  • #16 Ann Both their forms were circular C was flat , Margin Curled D was convex, Margin Entire
  • #17  Anibal The reaction of our bacterias to m.Luteus and e.Coli proved negative since they did not inhibit them
  • #18 Ramon The bacteria dont inhibit E.coli and M.lutheus
  • #19 Ann Sample A(1) bacteria proved positive, Sample B both bacteria proved positive with the initial primers C & D were negative but should be exposed to future work regarding them both.
