The Department of Biology, in cooperation with the Continuing Education Unit at the College of Science, held a lecture entitled “Purification of Bacteriocin” with the participation of a number of students, professors and those concerned with the subject of the lecture. The aim of the lecture was to introduce the separation of bacteriocin and its purity, which is the removal of materials and other compounds found with the protein material and obtaining it with a high degree of purity in order to study its distinctive properties and improve its ability to save when used in food, through many methods used in purification and varying from one type of bacteria to another.
The lecture was presented by the Assist. Prof. Dr. Hassan Majid Rashid who dealt with identifying the basic steps in tracking the concentration of bacteriocin in the lowest volume by separating solids with centrifuge and filtration sedimentation using ammonium sulfate, stressing the need to modify pH, because these vital products, which are sensitive compounds that may be effective only under certain conditions of hydrogen and temperature, stressing that the choice of the necessary scientific methods and their use to separate the product efficiently should be taken care of by using the product efficiently through the use of the technology of chromatography that is ion exchanger depending on the type of purified bacteriocin, whether it is positive or negative and to estimate the concentration of protein at each step of purification seemed from the raw shape (crude) to the full purified form.
