Escherichia Coli Experiment

Various studies have focused on the bacteria Escherichia coli and how it has evolved and built resistance to different types of antibiotics. Scientists have also discovered significant information by studying this bacteria, it is known how they are beneficial and harmful to other living beings. Although the nature of this bacteria has been studied intensively, in this experiment the focal point of is to observe the effects of the antibiotic streptomycin and the biocide triclosan on the bacteria E. coli and how these can influence the size of zone of inhibition. We have identified how the zone of inhibition increases and decreases in size by measuring its diameter and how E. coli mutates and survives when these treatments are present.
