It is my understanding that the yeast in the beer will consume everything it can and that is what keeps the beer preserved, or safe to drink.
While yeast will consume most of the nutrients, there's still residual sugar in beer. Hops will inhibit microbial and bacterial growth, but they will not stop it completely.
