Some Effects of High Velocity Electrons on Wood

Gamma-ray irradiation as a pretreatment for the enzymatic hydrolysis of cellulose

“…According to Lawton et al (1951), --cleavage of the S-1,4-glucosidic bonds is apparently random, with the crystalline and amorphous cellulose equally affected by the radiation. Phe effects of different types of high energy radiation appear to be similar; however, it has been found that the total absorbed dosage is important while the dose rate is not.…”

Ammonium Hydroxide Treatment on Wheat Straw

“…Increased VFA production during the in vitro fermentation indicated that breakdown products of irradiation were largely available to the rumen microbes. Lawton et al (1951) concluded that in gamma irradiated wood, cellulose seems to be affected rather than lignin. Mater (1957) reported that one effect of high energy irradiation was the breakage of lignin-cellulose bonds which increased cellulose digestibility.…”

The Influence of High Energy Radiation on Cotton

“…' DURING recent years, investigations have been carried out on the influence of high energy radiation on cellulose. Lawton et al studied the effect of beta rays on wood [13]. They found a greater measurable action of the irradiation on cellulose than on the lignin component of the wood.…”
