Table 2.
Viable counts of bacteria and actinomycetes in sediments from different depths in the Trondheim fjord after plating onto selective agar media. The numbers are mean values of CFU (colony forming units) per mL wet sediment.
| Sample ID | Medium | CFU/mL wet sediment | ||
|---|---|---|---|---|
| Bacteria | Streptomyces-like | Non-Streptomyces actinomycetes | ||
| N.D. - Not detected, no colonies on the agar plates. Plates were incubated at 20 oC for up to 4 weeks. | ||||
