The invention relates to a bioflocculant
fermentation method, in particular to a bioflocculant
fermentation method with a
mycelium pellet as a vector. The method solves the problems of
high energy consumption, high production cost and unsuitability for large-scale industrialized
fermentation production and the like existing in the existing bioflocculant fermentation method and comprises the following steps of: 1, mixing
rhizobium radiobacter with
bacillus sphaericus and then culturing so as to obtain flocculant-producing
bacteria seed liquid; 2, culturing
aspergillus niger to be a mature
mycelium pellet; 3, mixing the mature
mycelium pellet with the flocculant-producing
bacteria seed liquid and then culturing so as to obtain a mixed mycelium pellet; 4, taking 24-hour as a fermentation period, and drawing out the mixed mycelium pellet after each fermentation period is finished and pouring the mixed mycelium pellet into fresh
culture mediums for culturing; and 5, repetitively operating the step 4 for 30-35 times and namely completing. According to the bioflocculant fermentation method provided by the invention, on the premise of guaranteeing stable flocculating rate, seed liquid demand is reduced, production efficiency is increased and production
energy consumption is reduced; moreover, the invention has great significance on large-scale industrialized production of bioflocculant.
