Evaluation of the genus of Caldicellulosiruptor for production of 1,2-propanediol from methylpentoses.

Caldicellulosiruptor species degrade l-rhamnose and l-fucose to 1,2-propanediol. Six of the nine species within the genus produced 1,2-propanediol from l-rhamnose and three utilized l-fucose to produce the compound. Yields of 1,2-propanediol up to 40.5% of the theoretical yield were observed from methylpentoses catabolism.
