absorbed onto antibiotic sensitivity disks (12.7 mm;
Schleicher and Schuell, No. 740-E) which were placed
directly onto the agar surface. The petri dish cultures were
sealed with Scotch Tape and incubated in light from a
tungsten lamp for 3-7 days at 28-30 degree C. Zone of
inhibition was measured from the edge of the disk in mm.
The radius of growth inhibition around the disk was judged
visually and microscopically.
Result : Concentration (ug/disk) zone of inhibition (mm)
0 0
500 0
1000 8
0 indicates no inhibition,
36 indicates complete inhibition.
No inhibittion was noted with ethanol controls.
