| description | The invention belongs to the field of bioengineering manufacturing, and discloses a method for preparing an antibacterial peptide feed additive through duplex mixed fermentation, which comprises the steps of bacillus licheniformis duplex pediococcus acidilactici seed liquid preparation, bacillus licheniformis duplex pediococcus acidilactici fermentation liquid preparation, high-pressure homogenate wall breaking, separation, ultrafiltration purification, spray drying and the like. The specific bacillus licheniformis (CGMCC No.24209) and pediococcus acidilactici are selected for duplex mixed fermentation, so that the antibacterial peptide crude product obtained after duplex mixed fermentation is high in antibacterial titer and has a very good antibacterial effect on wheat gibberella; the characteristic that aerobic bacteria and anaerobic bacteria are complementary in physiological characteristics in the fermentation process of bacillus licheniformis and pediococcus acidilactici is utilized, so that the activity |
