You don't need "elaborate" "biochemical" analyses for this. A simple LB
and/or McConkey's (sp?) plate should be enough to show the presence or
absence of bacterial population. To show presence of fungi, you need a
general VM type medium (low pH). I am not sure about protozoans.
Whether ET life behaves the same way is another matter, and is anybody's guess.
