Modeling of Sensory Characteristics Based on the Growth of Food Spoilage Bacteria
D. Valenti, G. Denaro, F. Giarratana +6
During last years theoretical works shed new light and proposed new hypothesis on the mechanisms which regulate the time behaviour of biological populations in different natural sy…
Noise Induced Phenomena in the Dynamics of Two Competing Species
D. Valenti, A. Giuffrida, G. Denaro +6
Noise through its interaction with the nonlinearity of the living systems can give rise to counter-intuitive phenomena. In this paper we shortly review noise induced effects in dif…
A stochastic interspecific competition model to predict the behaviour of Listeria monocytogenes in the fermentation process of a traditional Sicilian salami
Alessandro Giuffrida, Davide Valenti, Graziella Ziino +2
The present paper discusses the use of modified Lotka-Volterra equations in order to stochastically simulate the behaviour of Listeria monocytogenes and Lactic Acid Bacteria (LAB)…
Application of an interspecific competition model to predict the growth of Aeromonas hydrophila on fish surfaces during the refrigerated storage
Alessandro Giuffrida, Graziella Ziino, Davide Valenti +2
The growth of Aeromonas hydrophila and aerobic natural flora (APC) on gilthead seabream surfaces was evaluated during the refrigerated storage (21 days). The related growth curves…
