| titleOfInvention | Method for biologically converting poplar bark lignin into polyphenol through ultrasonic wave synergistic mixed bacteria |
| abstract | The invention discloses a method for biologically converting poplar bark lignin into polyphenol through ultrasonic wave synergistic mixed bacteria. The invention relates to a method for biotransformation of poplar bark lignin into polyphenol by ultrasonic wave synergy, which comprises the following steps: the method comprises the steps of obtaining fresh poplar barks through mechanical extrusion, sun-drying the fresh poplar barks (the water content is less than 5%) and then crushing the fresh poplar barks into 60-mesh bark powder as a raw material, using a fungus microorganism nutrient solution to pretreat the bark powder at room temperature according to a certain solid-to-liquid ratio by using an ultrasonic generating device through ultrasonic waves emitted by an ultrasonic rod, mixing the fungus microorganisms in a certain volume ratio by using 3 fungus microorganisms, co-inoculating the fungus microorganisms into a solution system, and performing biotransformation for a period of time under the conditions of a certain temperature, pH and rotating speed to realize the high-efficiency enrichment of total polyphenol in the poplar barks and the high-efficiency degradation of lignin. Compared with the method for directly converting the total polyphenol by the microorganisms, the method can improve the total polyphenol efficiency by more than 35 percent, improve the lignin degradation efficiency by more than 10 percent, has the characteristics of simplicity and easiness in operation, strong compatibility, low cost, high efficiency and the like, and can provide a new idea for the bioconversion of the abundant woody lignin in China into the polyphenol. |
