Ms. Imane Maiouet research focuses on microbial biotechnology with a specialization in the isolation, technological characterization, antimicrobial profiling, and probiotic assessment of lactic acid bacteria (LAB) derived from dairy sources. Core investigations include phenotypic, biochemical, physiological, and molecular identification of LAB strains, followed by detailed evaluation of their fermentation behavior, acidification capacity, growth kinetics, and enzymatic activities. The work further explores antimicrobial mechanisms through agar diffusion assays, OD-based inhibition tests, and co-culture studies aimed at suppressing foodborne and clinical pathogens. A significant component involves identifying, purifying, and optimizing LAB-derived bioactive compounds, particularly bacteriocin-like substances, with potential applications in food safety and functional probiotics. Probiotic characterization includes assessing acid and bile tolerance, hydrophobicity, aggregation behavior, gastrointestinal resilience, enzymatic traits, and safety indicators such as hemolysis and antibiotic susceptibility. Additional studies address the technological performance of LAB in dairy environments, the impact of different processing conditions, and the development of strains with enhanced antagonistic and functional properties. Parallel research has examined biotechnological applications related to spoilage inhibition, environmental microbiology, and the integration of data analysis workflows using Python and statistical tools. Collectively, this work advances the development of beneficial LAB strains with promising industrial, probiotic, and biopreservative potential.
