Describe your results from the DNAse agar plates. What are your overall conclusions about the bacteria.
Principle of the experiment : The DNAse agar plate experiment is used to test the ability of an bacteria to produce DNAse.
(Expected) Results :
Positive - When DNA is hydrolysed, methyl green is release which turns the medium colourless around the test bacteria.
Negative - When there is no degradation around the test bacteria i.e the medium remains green.
Conclusion : The colonies producing DNAse hydrolse the DNA. This is evident from the colourless patch aorund these colonies. Whereas, bacteria who dont produce DNAse doesnt hydrolse the DNA.
