Granite milling experiments at 67 °C showing H2 consumption and CH4 production when inoculated with a methanogenic community.
  1. Experiment 1: rotating with granite balls.
  2. Experiment 2 grinding with magnetic stirrer.
  3. Experiment 3: grinding with an abrasive resistant stirring bar. Triangle = H2, solid circle = CH4. Shading shows milling periods and arrow shows inoculation with methanogenic community.
