Optimum Membrane Structures for Growth of Coliform and Fecal Coliform Organisms [PDF]
Applied Microbiology, 1975 The purpose of this study was to determine the optimum membrane filter structure and characteristics for recovery of coliform organisms. Additionally, other factors such as sterilization method and membrane composition were examined. Fecal coliform growth tests with varied samples indicated that the most critical factor in recovery was surface pore ...

Sanitary Significance of Coliform and Fecal Coliform Organisms in Surface Water [PDF]
Public Health Reports (1896-1970), 1964 THE SCIENCE of sanitary wat,er bacteriology began in 1880 when von Fritsch described Klebsie7la pneu-monia and K. rhinoscleromatis as organisms characteristic of huiman fecal contamination. A short time later Escherich identified Bacillus coli as an indicator of fecal pollution.

Microbiological Guideline Values for Recreational Bathing in Canada: Time for Change?
Canadian Journal of Infectious Diseases and Medical Microbiology, Volume 18, Issue 2, Page 153-157, 2007., 2007 Recreational bathing is an activity practiced by thousands of Canadians every year. While its health benefits are numerous, bathing in polluted water can also be a source of health problems. These problems are generally nonspecific and are difficult to detect through usual health monitoring systems.

Comparison of Fecal Coliform Agar and Violet Red Bile Lactose Agar for Fecal Coliform Enumeration in Foods [PDF]
Applied and Environmental Microbiology, 2002 ABSTRACT A 24-h direct plating method for fecal coliform enumeration with a resuscitation step (preincubation for 2 h at 37 ± 1°C and transfer to 44 ± 1°C for 22 h) using fecal coliform agar (FCA) was compared with the 24-h standardized violet red bile lactose agar (VRBL) method.

Survival of Fecal Coliforms in Dry-Composting Toilets [PDF]
Applied and Environmental Microbiology, 2001 ABSTRACT The dry-composting toilet, which uses neither water nor sewage infrastructure, is a practical solution in areas with inadequate sewage disposal and where water is limited. These systems are becoming increasingly popular and are promoted to sanitize human excreta and to recycle them into fertilizer for nonedible plants ...

Improved Membrane Filter Method for Fecal Coliform Analysis [PDF]
Applied Microbiology, 1975 A two-layer agar method has been developed which consistently yields higher recovery of fecal coliforms on membrane filters when compared to the existing membrane fecal coliform procedure. This method has been evaluated by three laboratories using samples of raw and chlorinated waste water, and reservoir, river, and marine waters. Verification of 1,013

Fecal coliform elevated-temperature test: a physiological basis [PDF]
Applied and Environmental Microbiology, 1978 The physiological basis of the Eijkman elevated-temperature test for differentiating fecal from nonfecal coliforms was investigated. Manometric studies indicated that the inhibitory effect upon growth and metabolism in a nonfecal coliform at 44.5 degrees C involved cellular components common to both aerobic and fermentative metabolism of lactose ...
