Can I use a petri dish to find bacteria in a soda?

Question

?

Answer 1

Sure.
The petri dish should contain bacterial growth medium that is sterile.
Using sterile bacteriological technique, inoculate the plate from the soda sample, and incubate the dish to see what grows.

Answer 2

Yes, you could use nutrient agar plates. Maybe spread plate 1ml of soda under sterile conditions onto the dish and incubate at 37oC for a few days. Of course you would have to exercise great care with sterile technique; perhaps use ethanol to sterilise the can and lid before opening. Considering the anti-microbial chemical treatment and acidity of soda you would perhaps not find anything! Or perhaps there are bacterial spores, bacilli or clostridia for example, that could survive. You could even look for fungi by using yeast-extract peptone dextrose agar (yepd). If you wanted to be thorough you could use polymerase chain reaction instead.

Answer 3

Sure. Just swab the soda and give it a good pattern on the dish. Maybe use some blood agar or some nutrient rich agar. Also, ensure that you incubate the dish!

Answer 4

Well there is no bacteria in a soda bottle . CO2 dissolved in water was first used to sterilize operating room . It is because the CO2 will kill most all bacteria.

Answer 5

I don't know why not.
