BACKGROUND The recalcitrant nature of cellulosic materials and the high cost of enzymes required for efficient hydrolysis are the major impeding steps to their practical usage for ethanol production. Ideally, a recombinant microorganism, possessing the capability to utilize cellulose for simultaneous growth and ethanol production, is of great interest. We… (More)

For the first time, artificial cellulosome structures were created on DNA scaffolds based on zinc finger protein (ZFP)-guided assembly. These resulting two-component cellulosome structures exhibited enhancement in cellulose hydrolysis compared to the non-complexed mixture depending on the number of CBMs and cellulases assembled.
Diethylcarbamazine (DEC) produced an initial stimulation followed by depression of the movements of the intact worm and nerve-muscle preparation of Setaria cervi. The effective concentration of DEC was reduced to one hundredth in the nerve-muscle preparation as compared to the whole worm, suggesting that the cuticular barrier is highly effective in… (More)
