Genetic variation in loblolly pine for efficiency in hydrolytic conversion to ethanol

The use of loblolly pine biomass for ethanol production presents some challenges; enzymatic hydrolysis of polysaccharides from softwood pulp typically produces lower yields of fermentable sugars than similar treatment of hardwood pulp. Many chemical and physical wood properties are subject to genetic control, and variation in these properties may well affect the efficiency of ethanol production. In this experiment, 17 clonal varieties of loblolly pine, chosen for a diverse range of chemical and physical wood properties, were tested to characterize variation in yield of fermentable sugars from enzymatic hydrolysis of pulps produced by two different pretreatments. Wood samples from three pooled ramets of each clone were tested, using enzymatic hydrolysis after dilute acid and alkaline pretreatments, to produce data on sugar yields for each clone.
