| Popis: | Culturable cells and non-culturable cells of fecal coliforms, obtained by irradiation at 312 nm were submitted to the combined stress conditions of salinity and starvation. After 14 days, β-galactosidase activity of UV-irradiated cells was at least twice the value of non-irradiated cells. UV-irradiated cells thus contribute more than non-irradiated cells to the enzyme assay after incubation in saline water. This finding is essential for the interpretation of quantitative investigations into the environment using enzymatic methods. |
