Plate Count of Biofilm Inoculum (matched at 1.0 McFarland)

  • Counted at 3 PM
  • at 10^-12: 129 x 4 = 516 colonies ==> 5.1x10^15 CFU/ml
    • other dilutions too many to count.


  • Too numerous due to starting inoculum (which was 5 ml of overnight 10-ml 1-loop culture suspension). Need to score growth at even higher dilutions to verify counting in one plate.
