Microbiology
a) For each of the following parameters, indicate amethod/approach that could be used to estimate it.
- Bacterial activity in the water of a lake
- The fraction of bacteria that are metabolically active in thewater of a lake
- The number of cells of a particular phylogenetic group ofmicroorganisms, e.g. methanogens
b) Design enrichment cultures for the following types ofbacteria. Recall the Winogradsky column
Organisms | Energy source | Carbon source | Terminal electron acceptor | Incubation conditions (anoxic/oxic, light,etc.) |
Cyanobacteria | | | | |
Purple sulfur bacteria | | | | |
Denitrifying bacteria | | | | |
Sulfate reducers | | | | |
