Specifically, can plant waste that naturally have anti-microbial properties be digested using microbes?

Which antimicrobial compounds are you interested in?

You can often evolve populations of bacteria to become resistant and to degrade recalcitrant compounds by growing them on gradually increasing concentrations. Have you tried that?

@Ben Libberton: I'm just at the literature review phase. But I'm looking at are various cannabis chemicals like triterpenoids, beta-pinene, cannabidiol, cannabichromene, cannabigerol, Δ9-tetrahydrocannabinol, and cannabinol.

Thats a good question. I can't think of any off the top of my head. If you can't find any I would test a panel of different strains using an antimicrobial susceptibility test to see if any show inherent resistance. Then I would try to evolve them to either, increase the resistance or break them down.
