One approach already in use is probiotics, the idea that friendly bacteria fed to cattle will displace O157.
Like in a cow's stomach, anaerobic bacteria feeding on waste in a landfill create a lot of gas.
Only bacteria fed on the carcasses, but rather than utterly destroying the bodies, this process often caused aspects of an organism's soft anatomy to be preserved.
When I was an undergrad, I spent long summers in labs streaking out yeast and bacteria, feeding flies, making reagents, and finally doing experiments in crystallography.
Fermentation is a process in which bacteria, fed by sugars, colonizes on food and changes their compositions.
Anytime sugar makes it to the colon (sucrose, fructose, lactose) it's a bacteria feeding frenzy and, therefore, fart city.
For bacteria feeding experiments, bacteria were centrifuged at 5,000 g for 10 min and resuspended in ddH2O to 250×.
On the other hand, deposit and bacteria feeding meiofauna could be in strong competition for food with the macrofauna.
While the cerebellum had a relatively low incorporation rate in animals fed with any 15N diet on PND5, bacteria fed animals showed an earlier increase of 15N incorporation in adolescence compared to blue-green algae fed animals (p<0.01).
