Interpretive Summary: There is an increased interest in using biomasses as renewable sources for producing sugars. In this study, the biomasses from four different saline crops were studied to evaluate their feasibilities for sugar production. The results showed that Creeping Wild Rye had the highest potential for sugar production.

Technical Abstract: Biomass can be a good renewable source for sugar production. Saline crops, including two woods, Athel tree (Tamarix aphylla L) and Eucalyptus (Eucalyptus camaldulensis), and two grasses, Jose Tall Wheatgrass (Agropyron elongatum) (JTW) and Creeping Wild Rye (Leymus triticoides) (CWR), were produced by using high salt subsurface irrigation water in California. The objective of this study was to evaluate and compare the potentials of different saline biomass to be used as raw materials for value-added sugar production, which can be further utilized as feedstock for ethanol and other chemical productions. The dilute sulfuric acid pretreatment and cellulase hydrolysis were studied to obtain 5C and 6C sugars from hemicellulose and cellulose, respectively. The results showed that CWR had the highest potential for sugar production.
