They then plated a “lawn” of each of the provided bacteria (one plate of E. coli and one plate of B. cereus) using either an ethanol-flamed bacteria spreader or sterile swabs. Ethanol-flamed forceps were then used to apply both extract-soaked and antibiotic-infused disks to each inoculated plate ( Fig. 1F–H ), and the plates were incubated for 24 hours at 37°C.
