Membrane filter method for recovery of fecal coliforms in chlorinated sewage effluents.
نویسنده
چکیده
The standard one-step M-FC broth-membrane-filter procedure for recovery of fecal coliforms from chlorinated sewage effluents is much less effective than the multiple-tube (most-probable-number) technique. A two-step membrane-filter method, using a pre-enrichment technique with phenol red lactose broth and incubation at 35 degrees C for 4 h, followether 18+/-2 h, enhanced fecal coliform recovery from chlorinated effluents. The results of 126 comparisons using chlorinated effluents from five wastewater plants showed that fecal coliform recovery by using the two-step membrane-filter method is comparable to that using the multiple-tube procedure.

Evaluation of Methods for Detecting Coliforms and Fecal Streptococci in Chlorinated Sewage Effluents
Total coliform (TC), fecal coliform (FC), and fecal streptococcus (FS) recoveries in chlorinated secondary sewage effluents were investigated by the membrane filter (MF) and multiple-tube (most probable number, MPN) methods. The LES two-step MF method was found to be comparable to the MPN procedure for determining TC. The TC detection was 1.5 times greater by the LES two-step technique than tha...
متن کاملMembrane filter technique for the quantification of stressed fecal coliforms in the aquatic environment.
A two-layer membrane filtration (MF) medium (injury-mitigating MF [IM-MF]) and a procedure for the enumeration of injured fecal coliforms are described. These procedures included the addition of glycerol and acetate plus reducing agents to both layers of a two-layer medium and rinsing of the filter with a rich resuscitation medium. Some changes in incubation time and temperatures were used. Thi...
متن کاملRapid, single-step most-probable-number method for enumerating fecal coliforms in effluents from sewage treatment plants.
A single-step most-probable-number method for enumerating fecal coliforms in sewage treatment plant effluents is described. The method requires the use of only one lactose-based medium and a single incubation temperature of 44.5 degrees C, and it can be completed in 18 h or less, as compared with up to 72 h for the standard most-probable-number method. The appearance of growth is the sole crite...
متن کاملFecal Coliform Organism Enumeration in Chlorinated Wastewaters
The accepted method for determining disinfection efficiency of wastewater treatment systems is routinely to perform fecal coliform bacteria analyses on the final effluent (5). Standard Methods for the Examination of Water and Wastewater outlines two procedures for fecal coliform analysis: the membrane filtration technique and the most-probable-number (MPN) method (1). For chlorinated effluents,...

In view of the differences that have been found between the most-probable-number and membrane filtration methods for the recovery of coliforms from chlorinated samples, the survival of total and fecal coliforms in UV-irradiated effluent samples, as tested by the most-probable-number and standard single-step membrane filtration methods, was compared. There were no significant differences in the ...
