microbialcontamination, etc ; food contamination; human health; Show all 3 Subjects
Abstract:
... Foodborne microbial contaminants exist in foods variously and pose a major threat to human health. Therefore, the fast and touchy orientation of microbial contaminants in food is critical for avoiding the emergence and spreading of foodborne maladies. Nanozymes have the advantages of multifunction, which show broad application potential in the analysis of microbial contaminants and the prevention ...

Abstract:
... Microbial contamination of surface waters is of particular relevance in low-income and middle-income countries (LMICs) since they often represent the only available source of water for drinking and domestic use. In the recent years, a growing urbanization, profound demographic shifts and drastic climate events have greatly affected LMICs capacity to reach access to safe drinking water and sanitati ...

Abstract:
... The action of nonthermal atmospheric air plasma, producing the rich amount of reactive particles from surrounding air, on strawberries microbial decontamination was investigated. The plasma produced by the multipoint AC corona discharge fed by a Tesla coil and applied on strawberries leads to a substantial reduction of microbial load without influencing the sensory properties like taste and color. ...

Abstract:
... The brewing activity in Andean Patagonia plays a very important role in the region's economy, being microbial contamination one of the main problems in terms of quality. The presence of contaminant bacteria and wild yeasts in beer generate microbiological, physical and chemical changes that impact on its sensory attributes. However, few breweries establish criteria and policies to guarantee the qu ...

Abstract:
... Controlling microbial contamination in foods using effective clean and green technologies is important in producing food with less contaminants. This study investigates the effect of photosensitization treatment using naturally occurring curcumin on inactivating Aspergillus flavus spores on peanuts. Light dosages of 76.4 J/cm² and 114.5 J/cm² at 420 nm were employed in combination with curcumin co ...

Abstract:
... Microalgae are photosynthetic eukaryotes that serve as microbial cell factories for the production of useful biochemicals, including pigments. These pigments are eco-friendly alternatives to synthetic dyes and reduce environmental and health risks. They also exhibit excellent anti-oxidative properties, making them a useful commodity in the nutrition and pharmaceutical industries. Light-harvesting ...

Abstract:
... Lanna painting is a unique type of painting in many temples in the Northern Thai region. Similar to most mural paintings, they usually decay over time partly due to the activity of microbes. This study aimed to investigate the microorganisms from two Lanna masterpiece paintings in two temples that differ in the numbers of visitors using both culture-dependent and -independent approaches. The micro ...

Abstract:
... The main microbial contaminants of rooms in which laboratory rodents are housed are bacteria and fungi. Restriction of microbial growth to below threshold levels requires the application of various sophisticated antimicrobial techniques that must be effective and safe for the animals. Some of the most commonly used techniques, including chemical disinfection, ventilation, filtration, sterilization ...

Abstract:
... A large portion of food is lost due to the damage caused by different environmental factors such as moisture, oxidation, irradiation, microbial contamination, and others. Thus, food should be protected from such damages by developing strategies, such as packaging, to enhance its quality, stability, and shelf-life. The usage of conventional petroleum-based packaging materials is a great risk to hea ...

Abstract:
... When in the tree xylem, maple sap is void of microbial contaminants, including bacteria, yeast, and molds. Once tapped, however, the liquid which is comprised primarily of water, becomes a nutrient reservoir for environmental microbiota. Introduction of microorganisms is exacerbated by poor sanitation practices, sap storage procedures, as well as environmental factors. Excessive microflora growth ...
microbialcontamination, etc ; aquifers; bedrock; effective porosity; groundwater; preferential flow; travel; uncertainty; water table; Show all 9 Subjects
Abstract:
... Flow in many bedrock aquifers is through fracture networks. Point to point tracer tests using applied tracers provide a direct measure of time of travel and are most useful for determining effective porosity. Calculated values from these tests are typically between 10⁻⁴ and 10⁻² (0.01% to 1%), with these low values indicating preferential flow through fracture and channel networks. Tracer tests ar ...

Abstract:
... Microorganisms colonize caves extensively, and in caves open for tourism they may cause alterations on wall surfaces. This is a major concern in caves displaying Paleolithic art, which is usually fragile and may be irremediably damaged by microbial alterations. Therefore, many caves were closed for preservation purposes, e.g. Lascaux (France), Altamira (Spain), while others were never opened to th ...
