Dynamic estimations of metabolic fluxes with constraint-based models and possibility theory

Abstract: ElsevierLlaneras Estrada, F.; Sala, A.; Picó Marco, JA. (2012). Dynamic estimations of metabolic fluxes with constraint-based models and possibility theory. Journal of Process Control. 22(10):1946Control. 22(10): -1955Control. 22(10): . doi:10.1016Control. 22(10): /j.jprocont.2012 it is easy to take extracellular dynamics into account. This work explores the benefits of using possibility theory to get these dynamic predictions. It will be shown that the possibilistic methods (a) provide rich estimates for… Show more

“…These methods originally provide static insights into metabolic routes, what allows to study cell cultures at a state of particular interest. Even though several extensions were proposed to include extracellular dynamics in the framework of MFA and FBA, 81 precise mathematical representation of reaction kinetics and regulation mechanisms remains a challenge. See the review for a concise overview of metabolic models.…”

“…In addition to traditional MPA methods, extreme admissible values of individual internal fluxes can be determined through computation of flux variability analysis (FVA) which consists in solving a simple linear programming problem ( Leighty and Antoniewicz, 2011;Llaneras et al, 2012;Vercammen et al, 2014 ). While the usual analysis provides an insight into the cell activity under specific growth conditions, in the course of the exponential phase or the stationary phase for example, several studies provide a dynamic overview over the whole experiment using FBA ( Mahadevan et al, 2002 ), MPA ( Fernandes et al, 2016;Zamorano et al, 2013 ) or FVA ( Richelle et al, 2016;Bogaerts et al, 2017 ).…”

“…When the environmental conditions of a culture change, dynamics should be considered to investigate cellular metabolism. To this end, the development of dynamic metabolic flux analysis (DMFA) techniques has been addressed (Leighty and Antoniewicz, 2011;Lequeux et al, 2010;Llaneras et al, 2012;Niklas et al, 2010;Vercammen et al, 2014). For instance, Lequeux et al (2010) extended MFA based on the transformation of time series of concentration measurements into flux values.…”

“…This method was illustrated with a fed‐batch fermentation of E. coli , but is presented by the authors as a generic method (e.g., useful for microbial, mammalian and plant cells). In the work of Llaneras et al (), dynamic extracellular concentration measurements are taken into account into a possibilistic MFA strategy by approximating the derivatives of the concentrations. This approach provides solution intervals, where the ranges of possible solutions are obtained by solving a set of minimum‐maximum linear programming problems.…”
