| | Yields of sugars from hemicellulose are only about 50 percent of theoretical with severe conditions of steam explosion. | | | Adding a trace of sulfuric acid catalyzes hydrolysis during the steam explosion so that milder conditions are used, and the yield of sugars from hemicellulose is 70 to 80 percent. | | | Most important is an opportunity to develop lignin as a product with more potential value than the ethanol. |

| | Genetic analysis of natural variation is particularly well-suited to the study of processes that are so central to the life of the organism that only subtle variations are tolerated. | | | We believe that the analysis of natural variation is a feasible approach to the identification of the genes underlying the complex process of hemicellulose biosynthesis. | | | On the other hand, working with natural variation can be difficult because the genetic differences, and therefore the phenotypic differences, are typically ‘weak’. |
