The College of Science, Mustansiriyah University discussed a Ph.D. thesis on the purification and characterization of beta-glucan extracted from certain types of lactic acid bacteria, studying its biological effects and potential applications in medicine and biology by the postgraduate student, Ms. Intisar Hussein Abdul Hameed.

The thesis aimed to purify and characterize beta-glucan produced by lactic acid bacteria and explore its biological potential, particularly in treating wound infections and enhancing certain vital bodily functions.

The thesis included the isolation and identification of lactic acid bacteria from various sources, the production, extraction, purification, and characterization of beta-glucan using advanced laboratory techniques, and the evaluation of several of the compound's biological activities.

The thesis demonstrated that beta-glucan possesses significant efficacy in inhibiting bacteria that cause wound infections, as well as its ability to reduce biofilm formation.
