What pathogen (Staphylococcus epidermidis or E. coli) is able to grow on a MacConkey Agar plate and why? Is this type of agar serving as differential, selective, or both? Explain why. How long does a viral culture take? A laboratory culture of bacteria is transferred to two pet...
If your experiment requires a 100 percent pure culture and you're using plastic Petri dishes, then its best use new dishes sterilized from the manufacturer. Do not reuse plastic Petri dishes if your experiment involves the use of live pathogens. The risk of cross-contamination is too great. R...
as the agar will set in its container before it can be poured. Obtain sterile petri dishes and pour enough to cover the entire surface area of the plate and at least half of its depth. Avoid overfilling the plates and preferably do not allow the agar to contact the top edge ...

The media was prepared according to previous methods [53] in round petri dishes with 9 cm diameter. One month old sterile A. thaliana plants were removed from their sterile media and placed on the edge of the minimal media plates. In total, 3 μl of B. subtilis culture was placed ...
