acquaintance, the Biodiesel brewer said "no problem, I can make good biobrew
out of it" and he did.
As usual, my comments are experientially based rather than scientific.
Makes sense that any bugs that naturaly unravel the molecular structure of
the oil make it easier to make bio out of it. I just did not want to run
smelly stuff through my engine out of the pail, suspecting acids to be
present that might eat the innards of the injection pump.
The transester process would precipitate any nasties (bug poop, slime,
acids, etc) into the glycerine cake at the bottom of the reactor, leaving
the bio clean. The methoxide used in the process will KILL (dismantle) any
living organisms in the oil (and you too, if not carefull!) leaving the
