"Without a significant innovation in cellulosic biomass like  plant stalks and wood chips, the biofuels market is likely to falter,  or at least lack the pace necessary to satisfy a significant percentage of  demand..." According a report by BioWorld Today, which bills itself as the  daily biotechnology newspaper. 
 "Corn cannot conceivably handle the displacement of  gasoline in the US anymore than crop-based ethanol can keep pace with global  gasoline consumption without running out of steam," the report added.  
 Oil squeezed from soybeans and oil  palm are being used to produce biodiesel. In both the cases of ethanol and  biodiesel, the prices for the feedstocks like corn and sugar have soared.  
 The BioWorld report said ethanol  production in the United States topped the 1 billion gallon annual production  mark with 1.1 billion gallons in 1992, and that production is expected to rise  to around 4.3 billion by end of 2006. 
 The report said it is possible that  corn farmers may be unequipped to handle the demand for biofuels feedstock if  the ethanol market grows by triple digits over the next two years, as may be the  case, according to the current growth rate.
