B

Explanation:

Microbial samples often contain a wide variety of microorganisms. By isolating one colony and culturing it overtime you can obtain a pure culture, in which all the cells correspond to that same culture. In some cases, some microorganisms depend on others to grow and live, so it is impossible to obtain a pure culture from them.
