title: Chain elongation of acetic acid and ethanol in the presence of a N2:H2 atmosphere. Replicate 2
organism: anaerobic digester metagenome
description: 550 ml serum vials with 150 ml active volume and sealed with rubber stoppers  10%  inoculum was used from a previous enrichment at the same conditions.  The pH was adjusted to 6.8 at the start of the experiment.  The headspace was nitrogen (1.4 atm) and Hydrogen (0.1 atm).
