The experiment consists of 5 steps—Inoculation‚ fermentation‚ cell lysis‚ inclusion body solubilization‚ and peptide purification. In the first two steps‚ E coli with Snake 6 peptides is cultivated. Ultraviolet–visible spectroscopy (UV-vis) is used to quantify bacteria through detection of their optical density (O.D.). After reaching a certain concentration in the fermentation batch‚ inclusion bodies (IBs) are extracted from these E coli by adding Bugbuster lysis solution and lysozyme. Polyacrylamide
