At the College of Agricultural Engineering Sciences, University of Baghdad, the defence of a Master’s thesis titled (Isolation and Identification of Di-Acetyl Producing Bacteria and Their Use in Some Food Applications) was conducted by the student Abrar Nafie Abdul-Ilah from the Department of Food Sciences.
The study aimed to select bacterial isolates from various dairy products that produce di-acetyl and determine the best source of isolation. It also aimed to produce di-acetyl compound from the most efficient local bacterial isolates. Additionally, the study examined some factors affecting the di-acetyl production by the producing bacteria, including the addition of various concentrations of substrates and different culture media.
The researcher recommended further research on other food sources for isolating di-acetyl producing bacteria that may have higher concentrations. It is also suggested to explore alternative methods for separating and extracting di-acetyl from the culture medium, and to study the impact of local isolates and their metabolic products on pathogenic, spoilage, and toxin-producing microorganisms.
Congratulations to the student for this success.
