We tested the effectiveness of antimicrobial substances by placing saturated disks on agar plates that were contaminated with E. coli and measured the inhibition zones.
We transformed E.coli bacteria with pGLO plasmid and grew the bacteria on selective mediums that controlled the expression of GFP with arabinose.
With a solution of Kool-Aid and water, we used the method of chromatography to test the polarity of the blue and red dyes in the drink.
We analyzed different high protein food samples in order to find out whether or not they contained genetically modified ingredients.
