  My guess (and a guess is as good as it gets) is the following order of happiness where all will be happy, just to a different degree: mould > yeast > Gram - > Gram +.

  @Pharma thanks

  Unpreserved?
  Ask which drunk gets the 1st beer when “drinks are on the house” announced - whatever bugs gets to it 1st.

  @PhilGeis preserved. My point was to blend preservative that is strongest against which organisms.

  I see. You need preservation that is strong against each of the bugs.
