| relative frequencies and significance of faecal coliforms as indicators related to water temperature. | the faecal coliforms at different sites of a hypereutrophic lake near valencia (albufera) were identified and their relative amounts established along an annual cycle. using lauryl tryptose broth at 35 degrees c, followed by incubation at 44.4 degrees c in 2% brilliant green bile, escherichia coli and klebsiella pneumoniae are practically the only coliforms present. a positive correlation was found between the water temperature and the relative amount of these two coliforms: k. pneumoniae predom ... | 1983 | 6359768 |
