Effects of volatile fatty acids on methanogenesis of methanol and of pregrowth with methanol on acetate utilization by methanogens
TLDR
In this paper, the effect of acetic acid and/or propionic acid on thermophilic methanogenesis of methanol as a sole substrate was studied using Methanosarcina species (MST-A1, CHTI-55 and MP).About:

Degradation of volatile fatty acids by differently enriched methanogenic cultures: Kinetics and inhibition
TL;DR: The results suggested that sludges acclimatized to the presence of VFA arising from substrate degradation could use them better than not acclimatsized sludge.

Substrate competition between methanogens and acetogens during the degradation of methanol in UASB reactors
TL;DR: In this article, the authors evaluated the effect of methanol concentration and inorganic carbon on the competition between acetogens and methanogens in an upflow anaerobic sludge blanket reactors.

Methanol degradation in granular sludge reactors at sub-optimal metal concentrations: role of iron, nickel and cobalt
TL;DR: In this article, the effect of sub-optimal trace metal concentrations on the conversion of methanol in an upflow anaerobic sludge bed (UASB) reactor was investigated by studying the effects of decreased influent trace metal concentration on the reactor efficiency and sludge characteristics.

The anaerobic conversion of methanol under thermophilic conditions: pH and bicarbonate dependence.
TL;DR: The thermophilic (55 degrees C) anaerobic conversion of methanol was studied in an unbuffered medium and in a phosphate buffered medium, in both cases without bicarbonate addition, and hydrogenotrophic methanogens were found to be resistant to exposure to such conditions.

Growth and Methanogenesis by Methanosarcina Strain 227 on Acetate and Methanol
Michael R. Smith,Robert A. Mah +1 more
TL;DR: Results suggested that methanogenesis from acetate, methanol, and H(2)-CO(2) may have some steps in common, as originally proposed by Barker.

Isolation and Characterization of a Thermophilic Strain of Methanosarcina Unable to Use H(2)-CO(2) for Methanogenesis.
Stephen H. Zinder,Robert A. Mah +1 more
TL;DR: The high numbers of Methanosarcina-like clumps in sludges from thermophilic digestors and the fast generation times reported here for Methanos Arcina strain TM-1 indicate that MethanosARCina may play an important role in thermophobic methanogenesis.
Anaerobic treatment process stability
TL;DR: Kotze et al. as mentioned in this paper investigated the relationship between anaerobic degradation and the production of methane gas and found that the degradation of the complex organic mat ter to fatty acids is usually caused by a rapid increase in the concentration of volatile acids with a concurrent decrease in methane gas production.
