Modelling of Nutrient Gradients in a Bacterial Colony Fraleigh, Steven P. and Bungay, Henry R.,, 132, 2057-2060 (1986), doi = https://doi.org/10.1099/00221287-132-7-2057, publicationName = Microbiology Society, issn = 1350-0872, abstract= Summary: Oxygen and substrate gradients were simulated with a finite-volume method for a variety of bacterial colony sizes and substrate concentrations. A spherical segment geometry and a Monod relationship for simultaneous substrate and O2 consumption were assumed. The results agreed well with previous theoretical and experimental estimates for gradients in microbial colonies., language=, type=
