Here is list of ingredients to prepare 500 ml of liquid Gluconcetobacter medium
Glucose - 10 g

Na2HPO4 - 1.35g
Citric acid - 0.75 g
Distilled or tap water - 500 ml

I failed growing slime mold, so I tried once again with three dishes (just in case!), but this time I keep all of them inside the cabinet in the lab. I've learnt form my 1st attempt that my room is not a suitable environment for growing the slime mold.
