Figure 4. Comparison of percentage of feedstock crop cellulose converted into glucose through conversion of ammonia fiber explosion (AFEX)-treated and untreated (UT) corn stover (CS) and rice straw (RS) cellulose hydrolyzed using 4 mL of transgenic rice soluble proteins containing 4.9% rice E1 heterologous enzyme compared with 15 filter paper units (FPU) of Genencor commercial Spezyme CP microbial endoglucanase and exoglucanase mix (unpublished data). Novozymes commercial microbial ß-glucosidase (6.5 mg 15 mL–1) was added to both the rice E1 heterologous enzyme and to the commercial mix enzymes to inhibit cellubiose inhibition. These results are similar to those published in Oraby et al. (2007).
