Geographical Locations

The proteolytic activity and volatile fatty acid production of 10 isolates of Clostridium botulinum type F from diverse geographical locations were determined. Two of the 10 strains were non-proteolytic, 3 were slightly proteolytic, and 5 were strongly proteolytic. The non-proteolytic cultures and the slightly proteolytic cultures produced acetic and butyric acid. The strongly proteolytic cultures produced mainly acetic, butyric, isobutyric, and isovaleric acid, and small to trace amounts of propionic, isocaproic, and caproic acid. The relative amounts of the various acids produced were markedly influenced by the growth medium. The addition of glucose to the growth medium caused an increase in the relative amount of butyric acid and a decrease in isobutyric and isovaleric acid.

High Productivity

High productivity and specificity in anaerobic digesters arise because complex microbiomes organize into a metabolic cascade to maximize energy recovery and to utilize the advantage that the gaseous end product methane freely bubbles out of the system. These lessons were applied to ascertain whether a reactor microbiome could be shaped to produce a different end product. The liquid product n-caproic acid was chosen, which is a 6-carbon-chain carboxylic acid that is valuable and that has a relatively low maximum solubility concentration for product recovery. Acetoclastic methanogenesis was inhibited by pH control and a route was provided for n-caproic acid extraction by implementing selective, in-line recovery. Next, ethanol was supplemented to promote chain elongation, which is a pathway in which short-chain carboxylic acids are elongated sequentially into medium-chain carboxylic acids with two-carbon units derived from ethanol. The reactor microbiome developed accordingly with the terminal process catalyzed by chain-elongating bacteria. As a result, n-caproic acid production rates increased to levels comparable to anaerobic digestion systems for solid waste treatment.
