Abstract


In china utilization of crop straw is very low,_a amount of crop straw were set on fire. This not only causes serious environmental problems, but also wastes a lot of renewable resources. Therefore, to explore the effective utilization way of straw is a very strategic task. Fermenting the straw to produce feed-protein, can avoid the waste of renewable resources, can remit the problem of the increase of population and the decrease of land and the shortage of feed-protein. The method of this test was that fermented the straw with microorganism in solid-state. For providing a basis for practical application, we have done the toxicology tests.Amination straw with ammonia in 35℃,5days. The method of this test is that fermenting the straw with Penicillium sp. and Torula allii in solid-state, in 35℃,5 days. The crude protein and true protein of the fermentation product respectively was 35.41% and 29.66%.Micronucleus test of bone marrow cell test and Sperm shape abnormality test in mice was performed in toxicology study. The result of Micronucleus test of bone marrow cell test shown that there is no significant difference (P>0.05) in each dose group and negative control group;_in mouse sperm abnormality test, there is no significant difference (P>0.05) in each dose group and negative control group. Its shown that the fermentation product has no damage and teratogenesis to somatoplasm, erythrocyte and germ cell.We had measured the MDA, T-SOD, GSH-PX and CAT of the heart, liver, spleen, stomach, kidney and brain. The organs from the mouse of sperm shape abnormality test. The results shown there is no significant difference (P>0.05) in each dose group and negative control group in each viscera of MDA, CAT, GSH-PX, T-SOD. Its shown that fermentation product have no oxidative stress influence to mice.
