Radiometric method for the detection of coliform organisms in water.
نویسندگان
چکیده
A new radiometric method for the detection of coliform bacteria in water has been described. The method is based on the release of (14)CO(2) from [(14)C]lactose by bacteria suspended in growth medium and incubated at 37 C. The evolved (14)CO(2) is trapped by hyamine hydroxide and counted in a liquid scintillation spectrometer. The method permits the detection of 1 to 10 organisms within 6 h of incubation. Coliform bacteria suspended in water for several days recover from starvation and may be quantitated by the proposed method. Bacteria from water samples may also be concentrated by filtration through membrane filters and detected by the radiometric assay.

Detection of coliform organisms in drinking water by radiometric method.
The radiometric method has been used for detection of coliform bacteria in water. The method is based on measuring the released metabolic 14CO2 from 14C-lactose in growth media containing coliform organisms incubated at 37 degrees C under continuous shaking. This rapid and sensitive radiometric method permits the detection of even single coliform organisms within 6 hours of incubation. Using th...

متن کاملInfluence of Enrichment Broth on Multiplex Pcr Assay
Although multiplex PCR amplification condition for simultaneous detection of total coliform bacteria, Escherichia coli and Clostridium perfringens in water sample has been developed, results with high sensitivity are obtained when amplifying purified DNA, but the sensitivity is low when applied to spiked water samples. An enrichment broth culture prior PCR analysis increases sensitivity of the ...
