  Mathematical models in Predictive microbiology for food safety

  By Ourdia Nouara Kernou, Amir Tahi Akila, Amir Nadir, Belbahi Amine, Kerdouche Kamelia, Madani Khodir

  Abstract: The study of predictive microbiology is predicated on the notion that populations of microorganisms react in a predictable manner to the conditions of their environment and that historical observations can be used to predict how populations will react in the future by looking at environments in terms of the dominant limitations they present. Predictive microbiology is a relatively new branch of the field of microbiology that has recently gained significant …

  Extraction of Xylanases from Media Based on three Agricolous Co-products by An Aqueous Two-phase System

  By Ourdia Nouara Kernou, Kamelia Kerdouche, Pr. Nawel Boucherba, Pr. Khodir Madani

  Abstract: Jonesia denitrificans BN13 grows very well on a medium made out of agricultural byproducts like orange peel, esparto grass, and retam; the relative enzyme activity of these three substrates was 0.662, 0.711, and 0.835 U/ml, respectively First time xylanases were effectively extracted utilising aqueous two-phase system (ATPS) that had 3.5% PEG, 14% KH2PO4/K2HPO4, and 9% KI, The inclusion of cells resulted in much improved output from the system, which is …

  Ultrasound-Microwave Technologies as Alternative Methods for Inactivation Bacterias in Fruit Juice

  By Ourdia Nouara Kernou, Amine Belbahi, Ghania Kaanin-Boudraa, Khadidja Adel, Pr. Khodir Madani

  Abstract: In the food industry, it is common practice to resort to methods that require maintaining high temperatures for just a limited amount of time in order to increase the product's quality while simultaneously lowering its risk of contamination. They provide a contribution toward the reduction of the potentially catastrophic impacts of heat deterioration. In fact, the undulating technologies are being employed for this purpose in increasing amounts; by using microwave …
