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...

This study was carried out to evaluate the microbiological accumulation capability of the demosponge Spongia officinalis var. adriatica. Six microbiological parameters were researched in two sampling periods in the water and in reared sponge samples coming from sites with different degrees of microbial contamination: an off-shore fish farm displaced off the Apulian coast (Southern Adriatic Sea)...
Bacteria- and virus-containing aerosols were studied during the late summer and fall seasons in a midwestern suburb of the United States before and during the start-up and operation of an unenclosed activated sludge wastewater treatment plant. The study showed that the air in this suburban area contained low-level densities of indicator microorganisms. After the plant began operating, the densi...
