Summary
Bioreactors are driving the upgrading of bio fertilizers from workshop production to industrialization.
Some typical cases show that its application can increase the activity of bacterial strains by more than 10 times, reduce production costs by 20% -30%, and significantly improve soil health and crop quality.
1、 Principles and advantages of bioreactor technology
Bioreactors rely on temperature pH、 Intelligent regulation of parameters such as dissolved oxygen and nutrient supply to achieve high-density cultivation of microorganisms.
For example, stirred reactors optimize oxygen transfer efficiency through mechanical stirring and are suitable for bacterial cultivation; The gas lift reactor utilizes gas circulation to reduce shear force, making it suitable for the growth of fungal mycelium.
Compared to traditional fermentation processes, bioreactors can increase the number of viable bacteria by 10-100 times, reduce pollution rates from>15% to<5%, and shorten production cycles by more than 50%.
Case 1: Large scale production of Bacillus subtilis
Adopting a 100 m ³ stirred reactor, combined with a segmented temperature control strategy (promoting growth at 32 ℃ for 0-12h and spore formation at 28 ℃ for 12-24h), and automatically triggering glucose supplementation through online detection of bacterial concentration.
Effect: The spore formation rate increased from 65% to 89%, and the number of viable bacteria increased from 8 × 10 ⁸ CFU/mL to 1.2 × 10 ¹⁰ CFU/mL.
The production cost has been reduced by 25 yuan/kg, the production capacity has been increased by 4 times, and the product shelf life has been extended from 6 months to 12 months.
Economic benefits: This microbial agent is used for planting a high-yield crop, combined with drip irrigation technology to reduce the incidence of root rot and achieve increased yield.
Case 2: Efficient Production of Trichoderma Spores
The traditional shallow solid-state fermentation has been upgraded to a 30 m ³ gas lift reactor with a fixed carrier to ensure appropriate ventilation.
Effect: Pollution rate significantly reduced, spore production significantly increased. The production capacity per unit area has been increased by 10 times, and the fermentation cycle has been shortened from 5 days to 3 days.
Economic benefits: In watermelon cultivation, the integration of wood mold agents with water and fertilizer significantly improves sugar content and taste.
Case 3: Empowering Small and Medium sized Microbial Fertilizer Enterprises
Using a 5-10 m ³ modular reactor with integrated PLC control system and remote operation and maintenance functions, it supports precise feeding and sterilization.
Effect: Energy consumption reduced by 20% -30%, and bacterial activity stability improved. Adapting to small and medium-sized production can effectively enhance soil microbial diversity.
Economic benefits: The equipment investment payback period has been shortened to 18 months, helping the enterprise's annual production capacity exceed 5000 tons.
