In order to identify any of the species in a mixed culture, you first have to isolate individual colonies and grow them in a pure culture. You can't perform tests to identify bacteria in a mixed culture.

What are 3 methods used to isolate microorganisms from a mixed culture?
It is necessary to make the colonies well-isolated from each other so that each appears distinct, large and shows characteristic growth forms.Most bacteria, many other microfungi, and unicellular microalgae, may be most commonly obtained by plating methods such as streak plate method, pour plate method and spread plate method.

Why is a needle used to isolate individual colonies from a spread plate or streak plate?
Between each set of streaks you sterilize the inoculating loop in the Bunsen flame. At the beginning of the next streak you overlap with the end of the one before. The effect of the technique is to "dilute" the bacteria by gradually spreading then over greater distances. Eventually, a point is reached where single bacteria are spaced sufficiently far apart for single colonies to grow without infringing their neighbors.
How does rain effect a plant's growth?
water is necessary for growing plants .....but sometimes water mixed with sulphur ,oxygen ,nitrogen in air due to which simple rain is converted into acidic rain which damages the plants growth because the soil is basic in nature.....
