Proplylene glycol is non-toxic. It is also has FDA approval and is commonly used as a food additive in many commercial foods. It is used as a humectant and stabilizer in many prepared fruits, vegetables and bakery goods, Also as a emulsifier in many prepared foodstuffs.

Since it is non-toxic I am not at all surprised that an organism can easily grow in its solutions with water.
