“…(vi) UV studies. Stock cultures were grown in TSB at 35°C for 24 h, and a 1.0-ml portion was subcultured daily into 9 ml of TSB for the 93-day study period. A 1.0-ml portion of each subculture was placed in a sterile petri dish and irradiated for 5 min with a broad-beam germicidal UV lamp (Canadian Laboratory Supplies Ltd., UV Products line, Toronto).…”

“…After a 30-min "development" colony differentiation appears sharper. The improvement is variously attributed to the effect of UV or infrared illumination, normal laboratory lights, or sunlight behind glass (3,4). These apparently contradictory opinions may each be correct under suitable circumstances.…”

“…For the second experiment, chicken and beef naturally contaminated with E. coli were used. For the ABP direct plating method, the procedure of Rayman et al (4) was used. Counts on HGMF were carried out as previously described (5,6).…”

“…For this reason, Hsing-Chen and Wu (25) developed a new medium, fecal coliform agar (FCA), to recover stressed fecal coliforms after preincubation (42) of inoculated plates for 2 h at 37 Ϯ 1°C before normal incubation for 22 h at 44 Ϯ 1°C. FCA medium contains bile salts; lactose; bromocresol purple, which becomes yellow if lactose is used by bacteria (13); and calcium lactate, which precipitates around colonies after reaction with carbon dioxide produced by fecal coliforms (11).…”
