Recognizing the inverse relationship between scope of inference and precision in similar bioconversion studies, coupled with the common approach of testing at a very small scale using milled wood and speciallydesigned high throughput devices for a large numbers of samples [16], the conversion yields of the four wood samples were compared without drawing conclusions about the specific genotypes. This supported a direct use of the wood chips that is more representative of overall biomass for chemical pretreatment, as well as the collection of energy data for post chemical pretreatment wood chip size reduction. These energy data are vital because of the unique strong physical integrity of woody biomass and because such information is an integral component of evaluating bioconversion potential of woody biomass [17,18].
