| titleOfInvention | Method for preparing microorganism oil and fat with corn stalk as raw material |
| abstract | The invention relates to a method for preparing microbial oil by taking corn stalk as a raw material. The corn stalk is hydrolyzed, and the hydrolyzate is condensed to have the total reducing sugar concentration of above 20 g/L, 0 g/L to 0.4 g/L of potassium dihydrogen phosphate and 0 g/L to 1.5 g/L of magnesium sulfate heptahydrate are added thereto, and are fed with a microbial seed liquid for producing oil according to a volume ratio of 5 to 20 percent after the sterilization, the aerated culture is carried out for 52 hours to 120 hours until the total reducing sugar concentration in the fermentation liquor is reduced to under 1 percent, thalli are collected in a centrifugation way, and the microbial oil is obtained through the conventional extracting method of organic solvent. Each 100 g corn stalk can obtain 16 g to 28 g microbial dry biomass containing oil with the oil content which accounts for 15 percent to 66 percent, and 2.4 g to 18.5 g microbial oil can be obtained through extracting the microbial dry biomass containing oil. The invention has the advantages that the raw material is inexpensive, the process is simple, and the process is easy and feasible, thereby being a new preparation method through which the renewable resource can be utilized, the extra agricultural land is hardly occupied, and the microbial oil can be continuously produced. |
