Fermentation of dilute acid hydrolysed pine could be achieved by all of 18 thermophilic glycolytic anaerobic bacteria tested, while only seven isolates representing the species Clostridium thermohydrosulfuricum, Thermoanaerobium brockii and Thermoanaerobacter ethanolicus were able to ferment undiluted hydrolysate. A strain of C. thermohydrosulfuricum , designated Rt8.B1, was notably better at fermenting the hydrolysate and was studied further. Studies showed that glucose and xylose present in the hydrolysate were utilized simultaneously, a phenomenon which also occurred in a medium containing glucose and xylose as the added carbohydrates.
