Bacteria often evolve defenses against other bacteria that compete for the same vital resources they need. If two bacteria both have limited room to expand, and both need anything from light to other "prey" bacteria, after a number of generations, those that spontaneously evolved to produce toxins that rival bacteria are sensitive to will win and continue to reproduce. By doing so, the toxin-producing bacteria will be more successful at reproduction by eliminating competition.
