WebbThe bacterial species that grow at a pH range above or below the preferred value would not survive. But, bacteria at optimum pH show the best growth in nearly neutral pH, i.e. 6.5-7.5. The acidic pH usually restricts microbial growth, and it is frequently used in food preservation methods. The basic pH also inhibits microbial growth.
WebbSOLVED:Below is data taken from a batch reactor of bacterial growth (after lag phase was over). The bacteria are allowed to grow as fast as possible for the first 2.5 hours, and then they are induced to produce a recombinant protein, the production of which slows the bacterial growth significantly.
