Want to Control Bacteria Growth? Control Moisture

We’ve all crinkled our noses when we’ve caught a whiff of wet clothes that sat in the clothes hamper too long. They smell bad. Our noses are warning us that bacteria are growing in those smelly clothes - and some types of bacteria can be bad for us. Bacteria in Healthcare Settings Bacteria in healthcare settings may not just be smelly. Some types of bacteria can ...

An alternative cooling tower disinfectant: On-site generated mixed oxidants

Favorable temperatures (80-110°F) and availability of nutrients make cooling tower systems ideal places for microbial growth. Accumulation of biofilm impedes proper heat transfer and secretes metabolic products that contribute to microbiologically influenced corrosion (MIC). The films also may propagate and release disease-causing bacteria. Control of microbial growth is traditionally achieved ...

Analysis of efficacy of UVGI Inactivation of Airborne Organisms Using Eulerian and Lagrangian approaches

Abstract Ultraviolet germicidal irradiation (UVGI) is increasingly used in health care facilities to kill airborne bacteria and control the spread of airborne infection among occupants. The most widely used form of UVGI is the passive upper-room lamps that generate a horizontal layer irradiance field above the occupied zone. In this study, the efficacy of killing airborne bacteria by upper-room ...

Bacteria in paint shops, a very common problem

Successful bacteria control with UV light in pre-treatment systems for painting at E. Krieg GmbH in Stuttgart. In almost all cases, parts to be painted must be clean and free of grease. To achieve this, the components are washed in pre-treatment systems. After washing at 50 - 60 ° C, the parts are usually rinsed with demineralized water and these baths are particularly susceptible to the ...

Disinfection of Escherichia coli and Pseudomonas aeruginosa by copper in water

When households lack access to continuous piped water, water storage in the home creates opportunities for contamination. Storage in copper vessels has been shown to reduce microbes, but inactivation kinetics of enteric bacteria in water by copper alone needs to be understood. This work characterized inactivation kinetics of Escherichia coli and Pseudomonas aeruginosa by dissolved ionic ...

Triclosan resistant bacteria in sewage effluent and cross-resistance to antibiotics

The purpose of this study was to identify triclosan tolerant heterotrophic plate count (HPC) bacteria from sewage effluent and to determine cross-resistance to antibiotics. R2 agar supplemented with triclosan was utilised to isolate triclosan resistant bacteria and 16S rRNA gene sequencing was conducted to identify the isolates. Minimum inhibitory concentrations (MICs) of organisms were ...

Isolation and characterization of algicidal bacteria and its effect on a musty odor-producing cyanobacterium Dolichospermum crassum in a reservoir

Algicidal bacteria that attack Dolichospermum crassum were isolated from the Karasuhara Reservoir in October 2010. Phytoplankton monitoring was performed from April 2010 to March 2011, and D. crassum was detected from August to November. At its peak frequency (in early October), it accounted for 23% of all phytoplankton cells. Heterotrophic bacteria were isolated from the surface water, and ...

Controlling Bacteria In a Clean Room Environment

Maintaining the integrity of a cleanroom is a constant battle. The first step to deciding which method, or combination of methods, to employ is to identify the prime sources of contamination. There are three prime sources of contamination through which the integrity of a cleanroom might be breached. First, there is the human element. While many processes might be automated, many situations ...

Paraben resistance in bacteria from sewage treatment plant effluents in India

Parabens, the antimicrobial preservatives used in cosmetics, food and pharmaceuticals, are often detected in the aquatic environment. Generally, sewage treatment plants (STPs) receive community sewage containing parabens, which are ultimately released into streams/rivers. In this study, bacteria in STP effluents were evaluated for their resistance to parabens. The susceptibility was in the ...
