general description of detachment for multidimensional modelling of
biofilms". Biotechnology and
Bioengineering, 91(6):651-669,
2005.
This page contains video files of the simulations presented in the
paper.
2D simulations from Case Study I
These simulations are analyzed in the Case Study I: steady state activity and structure of a biofilm presented in the paper. Simulations were carried out with the same parameters with the exception of the kdet value.
| Simulation | Quick Time movie | AVI movie |
| IA (kdet=95m-1h-1) | kdet95.mov | kdet95.avi |
| IB (kdet=31.7m-1h-1) | kdet31.7.mov | kdet31.7.avi |
| IC (kdet=9.5m-1h-1) | kdet9.5.mov | kdet9.5.avi |
| ID (kdet=3.17m-1h-1) | kdet3.17.mov | kdet3.17.avi |
| IE (kdet=0.95m-1h-1) | kdet0.95.mov | kdet0.95.avi |
3D simulations from Case Study I
Simulations were also carried out in 3D for the cases of kdet=95m-1h-1 and kdet=3.17m-1h-1.
| Simulation | Quick Time movie | AVI movie |
| 3D at kdet=95m-1h-1 | 3d_kdet95.mov | 3d_kdet95.avi |
| 3D at kdet=3.17m-1h-1 | 3d_kdet3.17.mov | 3d_kdet3.17.avi |
2D simulations simulations from Case Study II
These simulations are analyzed in the Case II: Influence of detachment in biofilm density presented in the paper. In that case study, the biomass is represented according to 3 components: heterotrophic active mass, extracellular polymeric substances (EPS) and inert material. Simulations were carried out with the same parameters, with the exception of the bulk concetration of substrate (CSbulk), which was changed.
| Simulation | Quick Time movie | AVI movie |
| IIA (CSbulk=0.1gCOD-S.L-1) | cs0.1.mov | cs0.1.avi |
| IIB (CSbulk=0.02gCOD-S.L-1) | cs0.02.mov | cs0.02.avi |
| IIC (CSbulk=0.008gCOD-S.L-1) | cs0.008.mov | cs0.008.avi |
| IID (CSbulk=0.004gCOD-S.L-1) | cs0.004.mov | cs0.004.avi |
| IIE (CSbulk=0.0015gCOD-S.L-1) | cs0.0015.mov | cs0.0015.avi |
| IIF (CSbulk=0.0008gCOD-S.L-1) | cs0.0008.mov | cs0.0008.avi |
