Biofilm Lab Results

Biofilm formation was tested under conditions similar to that of seawater conditions using artificial seawater prepared in lab, which contains main salts and concentrations found in seawater. This test was done as a control to observe biofilm formation under standard conditions of artificial seawater.

Results indicated that biofilm was formed since absorbance is directly related to biofilm formation, and any increase in the absorbance is directly related to biofilm formation. We have found also that DH5 is capable of forming biofilm.

Different samples Average Absorbance Standard Deviation
DH5 0.2615 0.07797649
SRB5A 1.1185 0.16140529
SRB7 1.3985 0.13931619
SRB8 1.44375 0.25075137
