[Digestion] Inactivation of pathogens

[Claudia wendland]

In Germany it is required by law to pasteurise the feedstock in case 
there is organic waste added. Pasteurisation is quite energy intensive.
 I made some experiments to acidify the feedstock (at 20 degrees for 5 
days) before feeding at pH around 4 and I got good results for 
inactivation of e-Coli.
Has anybody experience with this type of pre-treatment?
