Created a chart (any way you would like) include in the chart if the media is selective,differential,enrichment-any special characteristics,what is it used for identification,what are the possible results (and any color changes or any other ingredients needed to analyze)and what are the interpretations of those results.
Media | Classification | Identification | Observation | Interpretation |
Mac Cokey Agar | Selective and Differential | For all gram -ve bacteria | Reddish-pink colonies indicates +ve result; colourless plates indicates -ve results | Reddish-pink colonies confirms the growth of gram -ve bacteria |
Blood Agar | Enriched and Differential | For all bacteria and for hemolytic organisms | Red plates would turn light yellow in the growth regions | Yellow coloured regions confirms the growth |
Eosin- Methylene Blue Agar | Selective and Differential | For gram -ve bacteria | Colour changes from Red to Blue to Black indicates +ve results; colourless plates indicates -ve results | Darker coloured colonies signifies fast fermentation rate |
Mannitol Salt Agar | Selective and Differential | For Staphylococcus aureus | Yellow coloured colonies indicates +ve results; colourless plate indicates -ve results | Yellow colonies confirms the growth of S. aureus in the media |
