Production of medium-chain carboxylic acids by Megasphaera sp. MH with supplemental electron acceptors.

ABSTRACT:

Background

C5-C8 medium-chain carboxylic acids are valuable chemicals as the precursors of various chemicals and transport fuels. However, only a few strict anaerobes have been discovered to produce them and their production is limited to low concentrations because of product toxicity. Therefore, a bacterial strain capable of producing high-titer C5-C8 carboxylic acids was strategically isolated and characterized for production of medium chain length carboxylic acids.

Results

Hexanoic acid-producing anaerobes were isolated from the inner surface of a cattle rumen sample. One of the isolates, displaying the highest hexanoic acid production, was identified as Megasphaera sp. MH according to 16S rRNA gene sequence analysis. Megasphaera sp. MH metabolizes fructose and produces v
