And when This is actually the circumstance, when these kinds of contaminated solution is subjected to sterility checks working with proper culture media, it is predicted which the contaminating organisms will increase and generate colonies (in the situation of strong culture media plates) or turbidity and/or gasoline production (for broth cultures) that offers impetus towards the existence of contaminating microorganisms.
