1. Development of high specific activity and selectivity of biocatalysts occupies an important position, use of genetic engineering to alter enzyme primary structure, directed evolution is the main way to realize biological cells.
2. The bioreactor performance greatly limited by the heat and mass transfer capability must be improved method and apparatus for heat and mass transfer in bioreactors.
3. Bioreactor is developing to maximization and automation, the reactor automatic detection and control system makes the reactor operating under the best conditions possible, with the maturing of biotechnology and the rapid development of automatic measuring and control system will play an increasingly important role.
