TECHNOLOGY FOCUS - BIOTECHNOLOGY - Preferred Method: The method involves cutting the bamboo material to a length of 20-30 mm to flake pigment, cleaning the sand, and filtering the hemicellulose extract, where the solid-liquid ratio of the extract is 3:1, heating the extract at 145-165 degrees C, maintaining the temperature at 120-200 degrees C, and subjecting the extract to hot water extraction to obtain sheet-type material. The method involves extruding the sheet-type material, rubbing split on the sheet-type material by the parallel double-screw extruder in the step (a), where the sheet material has larger extrusion pressure, extruding the sheet-type material, rubbing the material to compress the sheet-type material in ratio of 4:1, squeezing the separated hemicellulose and lignin extract from the compressed material to obtain the residual filament material, adding the fine material quality residual filament material base (3-21 wt.%) and the thread material (3) of the total mass of the hydrogen peroxide of 4% continuously to obtain the filament material process, control the friction temperature of the method to 90-120 degrees C. The method involves preparing cellulose depth extraction and bamboo pulp in the step (b) by subjecting the filament material to treatment process at high-temperature and high-pressure reaction in kettle, where the solid-liquid ratio of the material is 4:1, adding alkali (13 %mass) to the reacted product, subjecting the product to steam heating at 170-200 degrees C, maintaining the temperature for 80-110 minutes, subjecting the product to degradation reaction, filtering the hemicellulose and lignin degradation solution to obtain the bamboo pulp. (4) The step (d) involves separating the hemicellulose from the mixed solution, and the residual liquid, separating the cellulose at 33-38 degrees C, subjecting the product to saccharification process at 5.5-6.5 degrees C, inoculating 11-13% of inoculating microzyme to ferment the saccharified product for 25-30 hours, purifying the obtained product. The method involves preparing biomass fuel particles from the bamboo raw material, residual liquid from the sludge and sewage treatment in step (d). The method involves cutting bamboo raw material into the sheet with 20-30 mm length, sand cleaning and removing the impurity from the product, assembling the product in boiler, heating the product to 155-200 degrees C and subjecting product to hot water extraction. The step (d) involves inoculating yeast, preferably mixture of Pichia pastoris, and P.stipitis SHR06-1, and the alcohol yeast.
