Dynamic-energy-budget-driven fruiting-body formation in myxobacteria

Abstract: We develop an interacting particle model to simulate the life cycle of myxobacteria, which consists of two main stages--the swarming stage and the development (fruiting body formation) stage. As experiments have shown that the phase transition from swarming to development stage is triggered by starvation, we incorporate into the simulation a system of ordinary differential equations (ODEs) called the dynamic energy budget, which controls the uptake and use of energy by individuals. This inclusion successfully … Show more

“…3(b)), which is rarely discussed in early DW models. In addition, our model generates quasi-periodic collective movements with marching bands when r → 1 indicating that the aggregations of animals are more likely to appear with food shortage [26,27], which is far different from many known dynamical interpretations based on the interaction between individuals [19][20][21][22][23]. One of the noticeable features in our results is the coexistence of both scaling mobility patterns in individual level and collective movement in population level.…”

“…This automatic formation of aggregation center is supported by the observations of Curtis et al [43], Holmes et al [29] and Hendrata et al [30] in their simulation models. These models included the turning and bending of cells as random fluctuations due to stochasticity in the models' algorithm.…”

“…In this paper, we show that our model successfully reproduces the array of social behaviors of M. xanthus at both low and high density, from single cells to the spontaneous formation of multicellular aggregation center involving thousands of cells without the necessity of creation of an artificial traffic jam, as used in some previous models [24] , [25] . This automatic formation of aggregation center is supported by the observations of Curtis et al [43] , Holmes et al [29] and Hendrata et al [30] in their simulation models. These models included the turning and bending of cells as random fluctuations due to stochasticity in the models' algorithm.…”

“…[17], nor the currently known quorum sensing circuits for EPS production are incorporated in those models. Dynamic energy budget descriptions of cell dynamics [63] might provide a sophisticated framework to describe the evolution of individual cells taking into account their mass, volume, maintenance, substance secretion, and the presence of nutrients, oxygen, and toxicants. However, extensions to biofilms are yet to be devised.…”
