    Content: There is a vital need to reduce enzyme costs to facilitate production of cost-competitive cellulosic ethanol and other products. End-product inhibition, declining substrate reactivity, enzyme denaturation, and non-productive binding of enzyme to lignin are among the factors that could account for the loss of enzyme effectiveness as enzymatic hydrolysis of lignocellulosic biomass proceeds. In addition, lignin and hemicelluloses, the other two most abundant components in lignocellulosic biomass besides cellulose, are believed to be responsible for high recalcitrance of lignocellulosic biomass to biological conversion. This study focused on investigating the effects of hemicelluloses on enzymatic hydrolysis and developing possible strategies to overcome their negative impacts. In the first part of the study, we identified that xylooligomers released from biomass during pretreatment and enzymatic hydrolysis are stronger inhibitors than long known for glucose and cellobiose. Furthermore, mixtures of xylooligomers of varying chain length were shown to dramatically decrease enzymatic conversion rates and yields of both pure cellulose and pretreated biomass. To clarify the relative importance of different xylooligomers, gel permeation chromatography (GPC) was applied to separate xylooligomers according to their chain length, and selected fractions were added to pure cellulose hydrolysis to determine their relative influence on rates and yields. The degree of inhibition was found to increase with xylooligomer degree of polymerization (DP), and cellulase exhibited a greater binding affinity for birchwood xylan than pure cellulose. All of these observations suggest that xylooligomers could competitively adsorb on cellulase, thereby reducing enzyme accessibility to cellulose and cellooligomers. Consequently, applying hemicellulase to hydrolyze xylooligomers to much less inhibitory xylose prior to adding cellulase reduced this undesirable binding and was more beneficial than adding hemicellulase and cellulase together.

    Content: We experimentally investigate the effect of timing of implementation of decisions on trust and trustworthiness. In the “Now” treatment, a standard trust game is run and subjects receive payment in the same date of the experiment. In the “Later” treatment, subjects make decisions in the same date as the now treatment, while the decisions are implemented (and hence payment) in a week. The later treatment captures a key feature of social interactions where decisions are often implemented in the future rather than immediately. Consistent with our model, we find that both trust and trustworthiness are lower in the later treatment. Our result thus suggests that individuals who discount utility from altruism to a larger extent than utility from monetary payoff will have less incentive to trust or be trustworthy when the decision is implemented with a delay
