College of Science, University of Mustansiriyah discussed a Ph.D. thesis on the biological effectiveness of microalgae extracts on some pathogenic microbes and cancer cell lines by the postgraduate student, Mrs. Zainab Nasrallah Salman.

The thesis aimed at studying the possibility of benefiting from microalgae of the fresh aquatic environment and using them for medical treatment, as well as relying on these algae to find alternative natural compounds that can be used to address the problem of antibiotic resistance.

The thesis highlighted collecting microalgae from different environments, identifying their selected types, purifying them, and extracting chemical compounds from them using hexane as a solvent using a Soxhlet device, as well as identifying the active compounds in the raw extract of the algae through gas chromatography-mass spectrometry (GC-Ms) and infrared spectroscopy (FT). -IR) and partial purification of some fatty acids from (Chlorella vulgaris).

The thesis demonstrated the effect of crude active compounds on some fungi isolated from patients with renal failure and widespread bacteria and testing their resistance to antibiotics based on (CLSI, 2022), as well as evaluating the cytotoxicity of partially purified fatty acids on two types of cancer cell lines (MCF7, SR). ), as well as one type of normal cell line (NHF).
