The behaviour of microorganisms in urban stormwater should be thoroughly investigated and understood to (a) design treatment technologies that can reduce the human health risks of utilising stormwater and (b) develop models which can accurately predict the levels of microorganisms in urban stormwater to aid in health risk assessments. A crucial part of understanding the behaviour of pollutants ...

Water bodies, which are monitored for microbial water quality by quantification of faecal indicator organisms (IOs), can contain various zoonotic pathogens contributed by livestock waste and other sources. Sediments can serve as reservoirs of IOs and other enteric microorganisms, including pathogens. Agrochemicals may influence the survival of these microorganisms in water bodies impacted by li...

Natural waters serve as habitat for a wide range of microorganisms, a proportion of which may be derived from fecal material. A number of watershed models have been developed to understand and predict the fate and transport of fecal microorganisms within complex watersheds, as well as to determine whether microbial water quality standards can be satisfied under site-specific meteorological and/...

Although minimal food processing strategies aim to eliminate foodborne pathogens and spoilage microorganisms through a combination of mild preservation techniques, little is actually known on the resistance behavior of the small fraction of microorganisms surviving an inimical treatment. In this study, the conduct of severely heat stressed survivors of E. coli O157:H7 ATCC 43888, as an indicato...

This article discusses the value and limitations of using microbial indicators to predict occurrence of enteric pathogens in water. Raw or treated sewage is a primary source of fecal contamination of the receiving surface water or groundwater; hence, understanding the relationship between pathogens and indicators in sewage is an important step in understanding the correlation in receiving water...

Microorganisms are present on many surfaces in foodservice operations (3,7) but juice dispenser tips are among those showing the highest total microbial counts (3). Tips dispensing other beverages (e.g., acidic carbonated beverages such as cola) were less prone to contamination than were those dispensing fruit juices (11). Although high total microbial counts alone do not indicate a food safety...

Dimethylnitrosamine and diethylnitrosamine, two potent carcinogens, are nonmutagenic when tested directly in microorganisms. Likewise l-naphthylamine and 2-naphthylamine are also nonmutagenic but the N-hydroxy derivatives are mutagenic in microorganisms. Apparently these compounds require metabolism to breakdown products which are then the proximately active agents, and microorganisms lack the ...

Heavy metal pollution represents an important environmental problem due to the toxic effects of metals. Their accumulation throughout the food chain leads to serious ecological and health problems. The remediation of environments metal contaminated through physico-chemical methods present major disadvantages such as high energy consumption, high costs and incomplete removal of metal ions. Bioso...

In this study, a total of 25 Lactic Acid Bacteria (LAB) isolates from 15 samples [4 burgers, 4frankfurters, 3 pastramis, 2 sausages and 2baby faeces] were screened for their ability to produce inhibitory substances against three microorganisms which isolated meat products: (Salmonella typhi, Staphylococcus aureus Escherichia coli). Other indicators (reference target organisms) obtained the Cent...

Most traditional approaches to anaphora resolution rely heavily on linguistic and domain knowledge. One of the disadvantages of developing a knowledgebased system, however, is that it is a very labourintensive and time-consuming task. This paper presents a robust, knowledge-poor approach to resolving pronouns in technical manuals. This approach is a modification of the practical approach (Mitko...
