Effect of different legume resource and technical parameters on urea hydrolysis

Urea hydrolysis is widely used in agriculture, environment and other engineering fields, among which urease contained beans can catalyze urea hydrolysis. The activity of legume plant leaching solution (LPLS) was investigated, including soybeans, black beans, mung red as well soybean hulls, leaves, stems pods. For the high economic efficiency, most suitable for agricultural fields than soybean-related parts extract. increases with concentration LPLS, while decreases gradually reaction time. When heating temperature reaches 25, 35, 45, 55 65 ℃, steady enzyme high. Enzyme after °C (i.e.75, 90 °C). Meanwhile, soaking time LPLS has a little effect on compared factors. These results make positive contribution to domestic production experimental basis.
