Fecal Coliform - an overview | ScienceDirect Topics Fecal Coliforms Testing for fecal coliforms directly is not a part of methods for the assessment of drinking water quality, but fecal coliform (or E coli) identification of confirmed total coliforms is necessary as a part of the completed phase of multiple-tube fermentation method Testing for fecal coliforms involves inoculation of either EC broth containing an inverted tube or MacConkey
Fecal Coliform - an overview | ScienceDirect Topics Fecal coliform refers to a subgroup of coliform bacteria that are specifically associated with fecal contamination, characterized as rod-shaped, Gram-negative, nonspore forming bacteria that can ferment lactose, producing acid and gas at 35–37°C They serve as indicators of sanitary quality in water and food, suggesting the potential presence of other pathogenic organisms AI generated
Spatiotemporal variability and key influencing factors of river fecal . . . Fecal coliform bacteria are a key indicator of human health risks; however, the spatiotemporal variability and key influencing factors of river fecal coliform have yet to be explored in a rural-suburban-urban watershed with multiple land uses
Coliform Bacteria - an overview | ScienceDirect Topics The presence of this organism may be an indicator of fecal contamination and be related to use of polluted irrigation water, the presence of feces, or poor sanitation and hygiene (Brackett and Splittstoesser, 1992) However, vegetables can harbor bacteria other than E coli that give positive fecal coliform tests
Microbial pollution of water with special reference to coliform . . . Among the coliform, Escherichia coli is the indicator of fecal contamination The multiple tube fermentation technique has been applied as a conventional way to detect coliform in water samples through the fermentation of lactose sugar with production of acid and gas
Coliform Bacteria - an overview | ScienceDirect Topics Coliform bacteria generally belong to four genera of the Enterobacteriaceae: Citrobacter freundii, Enterobacter cloacae, Enterobacter aerogenes, E coli, and Klebsiella pneumoniae Some coliform bacteria are associated with the intestines (colon) of warm-blooded animals (called fecal coliforms), while others are related to plant material
Environmental factors influencing the distribution of fecal coliform . . . Fecal coliform bacteria (FCB), a group of coliform bacteria originated from gastrointestinal tracts and feces of warm-blooded animals including humans, have long been used as an indicator for bacterial pollution in aquatic environments The presence of FCB in waterways may indicate a potential risk for pathogens to occur
