微滤膜偶联生物反应器制备泡菜发酵剂
Production of Pickle Starter by Bioreactor Coupled with Micro-filtration Membrane
摘要
Abstract
In this paper, the bioreactor with micro-fihration membrane was developed and prepared for the liquid starter used directly for pickle fermentation. The results showed that, the pH, temperature, dissolved oxygen and time for nutrients addition could be controlled by this bioreaetor and the viable cell concentrations of LactobaciUus plantarum reached （5 -8） × 10^9 CFU/mL with constant pH after 12 h. Under the optimum operation conditions of membrane filtration（ the peristaltic pump speed 50 r/min and the pressure 0. 15 MPa） , the viable ceils of the concentrated broth was about （2 - 3） × 10^10 CFU/mL, and the suspensions could be used as the starter after diluted by 5000-fold. Under room temperature, the high-quality pickle was obtained after 3 d, less than the natural fermentation of 2 d. With its simple structure, convenient use and high degree of automation, this bioreaetor is suitable for continuous large scale industrial production of pickle fermentation.关键词
