Zusammenfassung:•We establish the existence and uniqueness results of time-space FDE of growing bacteria.•We introduce the numerical solution for this equation using a homotopy method.•We study the Ulam stability of it utilizing fractional inequalities.•We apply the above result to segment images of bacteria. A biological dynamic system carries engineering properties such as control systems and signal processing (or image processing) addicted to molecular biology at the level of bio-molecular communication networks. Dynamical system features and signal reply functions of cellular signaling pathways are some of the main topics in biological dynamic systems (for example the biological segmentation). In the present paper, we introduce new generalized hybrid time-space dynamical systems of growing bacteria. We impose the approximate analytic solution for the system. The generalization adapted the concepts of the Riemann–Liouville fractional operators for time and the Srivastava–Owa fractional operators for space. Moreover, we introduce a numerical perturbation method of two operators to obtain the approximate solutions. We establish the existence and uniqueness results and impose some applications in the sequel. Moreover, we study the Ulam stability and apply these stable solutions to improve the segmentation of a class of growing bacteria.
