Aggregation Patterns in Stressed Bacteria
Physical Review Letters
We study the formation of spot patterns seen in a variety of bacterial species when the bacteria are subjected to oxidative stress due to hazardous byproducts of respiration. Our approach consists of coupling the cell density field to a chemoattractant concentration as well as to nutrient and waste fields. The latter serves as a triggering field for emission of chemoattractant. Important elements in the proposed model include the propagation of a front of motile bacteria radially outward formdoi:10.1103/physrevlett.75.1859 pmid:10060409 fatcat:trq2okot65gojeqmt3c7iz6xru
