Bij alcoholische gisting van mengsels waarin zich pentosen (vijfwaardige suikers), zoals arabinose, bevinden kan methanol als bijproduct ontstaan (suikers zoals maltose en glucose zijn zeswaardig, oftewel hexosen). De vijfwaardige suiker xylose ontstaat bij afbraak van hemicellulose. Wanneer deze pentosen meegisten en er gisten aanwezig zijn die deze suikers kunnen omzetten (lang niet alle giststammen doen dit) ontstaat er (ook) methanol. De meeste ongelukken met methanol ge… WebSince methanol contains oxygen, the stoichiometric air-fuel weight ratio de-creases from 14.1 to 12.1 as the methanol content of the fuel is increased from 0 to 25%.
