I have captured a strain of wild yeast by dunking some of my backyard fruit in a solution of sugar and yeast nutrient, and so far it was been fermenting nicely. As expected I also caught a bunch of bacterial infections with it as well.I don't have the resources to properly culture it in petri dishes and collect a yeast only colony on an inoculation loop. I'd like the experiment with a clean strain of the yeast, so I need a way to kill of the bacteria, but not the yeast.
Any ideas of a cheap way of doing that?
