Which antibiotics will kill bacteria but allow yeast to grow?

Is there a broad spectrum antibiotic that will kill / slow down most bacteria, but will not affect yeast at all?

I am looking for a way to select for yeast in soil samples. I have found that most of my cultures are taken over by bacteria instead of yeast, even if I make sure that yeast is present (such as by adding yeast to the sample). This antibiotic must not affect the yeast at all; for example, yeast can survive chloramphenicol but they grow much, much more slowly in the presence of it.
Does such a thing exist? Or any ideas on where I should search? The problem is finding out if a given antibiotic affects yeast or not. The literature (that I have found) is not helpful.
