bioreactorBy controlling key parameters such as temperature, pH value, oxygen concentration, and nutrient concentration, a suitable reaction environment is provided for biocatalysts (such as enzymes and cells). The core principles include:

Environmental condition control: By adjusting temperature, pH value, oxygen concentration, etc., to meet the growth and metabolic needs of organisms.

Mixing and Mass Transfer: Using methods such as agitators or gas injection into the system to maintain uniform mixing of reactants and organisms, thereby improving mass transfer efficiency.

Output and by-product control: By controlling the parameters of the reaction process, optimizing the yield of products and reducing the production of by-products.

Monitoring and regulation: Equipped with a sensor system to monitor key parameters in real-time during the reaction process, and adjust control parameters based on feedback signals to maintain optimal reaction conditions.

　　bioreactorIt can be classified according to different classification criteria, and the following are common classification methods:

According to geometric shape or structural features: kettle type, tube type, tower type, membrane type, etc.

According to catalyst type or culture object: enzymatic reactor, microbial culture fermentation tank, plant cell reactor, animal cell reactor, etc.

According to the oxygen supply method: aerobic bioreactor and anaerobic bioreactor.

According to the mixing and energy input methods: stirred fermentation tank, air lift fermentation tank, jet circulation fermentation tank, etc.

According to the operating mode: intermittent bioreactor, continuous bioreactor, and semi continuous bioreactor.

According to the distribution of biocatalysts: biomass reactor and membrane bioreactor.

According to the flow and mixing state of the reactants: fully mixed flow bioreactor and piston flow bioreactor.
