NOVELTY - Fermenting agriculture and forestry wastes to produce the biological oil comprises carrying out enzymolysis, liquid culture manufacturing, fermenting, and biological oil extracting; where the enzymolysis process uses the cellulose zymin to perform enzymolysis on the fabric agriculture and forestry wastes to obtain the enzymolysis liquid; the liquid culture manufacturing process comprises adding one of urea and bean pulp in the enzlymolysis liquid in concentration of 50-200 g/L to obtain two mixtures; where the amount of urea or bean pulp is 2-10 g/L.    USE - The process is useful for fermenting agriculture and forestry wastes to produce the biological oil (claimed).    ADVANTAGE - The process can convert the biological agriculture and forestry wastes to the micro-organism oil product effectively. Moreover, it is environment-friendly.    DETAILED DESCRIPTION - Fermenting agriculture and forestry wastes to produce the biological oil comprises carrying out enzymolysis, liquid culture manufacturing, fermenting, and biological oil extracting; where the enzymolysis process uses the cellulose zymin to perform enzymolysis on the fabric agriculture and forestry wastes to obtain the enzymolysis liquid; the liquid culture manufacturing process comprises adding one of urea and bean pulp in the enzlymolysis liquid in concentration of 50-200 g/L to obtain two mixtures; where the amount of urea or bean pulp is 2-10 g/L; adding 0.5-1.5 g/L of organic salt ion magnesium sulfate (MgSO4), 2-3 g/L of potassium dihydrogen phosphate (KH2PO4), 2-6 mg/L of zinc sulfate (ZnSO4), 0.1-0.3 mu mol/L of manganese dichloride (MnCl2), and 0.1-0.3 mg/L of copper sulfate (CuSO4); adjusting pH at 5.0-7.0; mixing the microorganism bacterial strain producing the oil; performing room temperature culture for 48-96 hours; and producing the liquid culture; the fermenting process comprises adding one of urea and bean pulp in the enzlymolysis liquid in concentration of 50-200 g/L to obtain two mixtures; where the amount of urea or bean pulp is 2-10 g/L; adding 0.5-1.5 g/L of organic salt ion MgSO4, 2-3 g/L of KH2PO4, 2-6 mg/L of ZnSO4, 0.1-0.3 mu mol/L of MnCl2, and 0.1-0.3 mg/L of CuSO4; adjusting pH at 5.0-7.0; mixing 5-20 wt.% of liquid culture amount; performing room temperature culture for 48-96 hours; and obtaining the fermenting solution; and the biological oil extracting process comprises collecting the bacteria from the fermenting solution under centrifugal action; using the ultrasonic cell crushing process to crush the cell; using the organic solvent to extract the oil of the crushed cell; where the organic solvent is the mixture of chloroform and methyl alcohol with weight ratio of 1:1-3; processing the extracted solution by pressure reducing evaporation to recycle the solvent; and obtaining the biological oil; or the organic solvent is the mixture of diethyl ether and the alcohol with weight ratio of 1:1-3; oscillating the extracted solution extracted with the oil and sewing it; centrifuging to obtain the supernate; recycling the diethyl ether alcohol by a rotary evaporator or the pressure reducing evaporating way; and obtaining the biological oil.
