Ordination of terminal restriction fragment (T-RF) frequency of the acetogenic community (by targeting of the fhs gene) by non-metric multidimensional scaling (MDS). TE effect estimate versus temperature effect estimate for each T-RF. The T-RFs that significantly associated with TE-addition at 37 °C (65 bp), temperature without TE-addition (116 bp; 581 bp) or with the combined temperature increase and TE addition (283 bp) are coloured blue, red and purple, respectively
