Screening of important autoinduction medium composition for high biaomass production of E. coli expressing recombinant bromelain

Bromelain, a naturally available therapeutic protease enzyme from pineapple stem, was expressed in Escherichia coli using autoinduction-based fermentation medium. There are numerous recombinant proteins functionally expressed in E. coli using this autoinduction approach. Preliminary media trials...
