3.2.3 values the minimum concentration of the extract to paint can inhibit bacteria. P. acnes (Minimal Inhibitory Concentration : MIC) 1. prepare extracts in various concentrations, the procedure is as follows: 1.1 using a screw cap test tubes, each tube has a liquid Broth tubes 1 ml address BHI, except 1 with 2 ml tubes. 1.2 enter extract 200 mg into tube 1 use pipettes substances extraction tubes 1 ml volume fill in tube 2. Repeat a similar 1.2 1.3 till 11 tubes (changes every time you change a pipette bulb.) Once mixed the slurry in a tube 11, better compatibility, use solvent extraction pipette 1 ml ampules that dropped 12 to the agar alone does not have the extract so use this as a positive control. 1.4 fuel fill P.acners the number 108 CFU/ml 105 – every tube. 48-hour curing conditions leading to an air temperature of 35-37° wireless c.
