Methanol based elongation of propionate and propionate and acetate in continuous and batch mixed culture systems



Continuous methanol based chain elongation of propionate to n-valerate was performed in a mixed culture reactor. Additionally, the study shows simultaneous methanol based elongation of propionate and acetate to respectively n-valerate and iso/n-butyrate in a continuous mixed culture reactor. A range of mixed culture batch experiments was performed with methanol and propionate and the initial pH ranging from 5 to 7.5 (steps of 0.5)
