The book "Nutritional and Ecological Optimizations for Exo-Inulinase Production" offers a comprehensive analysis of inulinase production, an enzyme that catalyzes the hydrolysis of inulin, a plant polysaccharide. Inulinase plays a significant role in the pharmaceutical and food industries as it is used for the extraction of fructoses and fructo-oligosaccharides. The authors, Alaa N. Mahammed Ali, Sahira Nsayef Muslim, and Istabreq Muhammed Ali Salman, explore the possibilities for optimizing the nutrients and ecological conditions for the production of this enzyme. Notably, the innovative use of Acinetobacter as a production organism is highlighted, as there have been no previous reports of inulinase production from this genus. The book is aimed at professionals and students engaged in enzymatic biotechnology and its applications in industry.
