Document Summary
Aerobic flocs (mentioned only will be presented with wastewater and sewage treatment) Use matrix/support for the cell to attach to instead of. Polysacchrides,proteins that allow cell to attach to surface. Cell decides to attach to your material. Therefore need high surface area so they can be colonized. Less common pure culture b/c cant nd better way submerged. Solid-phase fermentations: solid support matrix for cells (e. g. , biofilm) to adhere to: i. e. , immobilized cells. Organic supports: wood chips, peat moss, particulate charcoal, rice or grains, cell flocs, plastic carriers. Anaerobic + aerobic processes in a single layer. Can have really complex interactions going on. More robust when attached - they"re protected and mmore resistant. Behave differently when in bio lm, genes turned on. 1 v a a e b r s a t s v e r i g m i r b l i o e c s w w w p t t h.
