Mycotoxins are naturally occurring toxic substances in foods, posing considerable health risk to humans. Microbiological decontamination of mycotoxins using microorganisms is one of the well-known strategies for the management of mycotoxins. Numerous organisms, including bacteria, fungi and yeasts have been tested for their ability in reducing mycotoxigenic fungi and resultant mycotoxin contami...

In cultural-heritage-related indoor environments, biological particles represent a hazard not only for cultural property, but also for operators and visitors. Reliable environmental monitoring methods are essential for examining each situation and assessing the effectiveness of preventive measures. We propose an integrated approach to the study of biological pollution in indoor environments suc...

The potential of microalgae as a biomass feedstock for biofuels, bioproducts and as a technological solution for CO(2) fixation is subject to intense academic and industrial researches. However, current microalgal mass culture technologies have failed to produce bulk volume of microalgal biomass at low cost, because the contaminations of biological pollutants become a big constraint in mass cul...

Corn, peanuts, cottonseed and tree nuts are the important commodities in which aflatoxin contamination can occur in the United States (Diener et al., 1987). Advanced technology has been developed to detect and remove the aflatoxins from these commodities and this permits some segregation of contaminated components and serves as a guide for detoxification (Goto and Manabe, 1989). Storage conditi...

Background The introduction of animal origin free (AOF) media has significantly reduced the incidence of adventitious virus contamination in biological production systems. Nevertheless, contamination by the parvovirus Mouse Minute Virus (MMV) remains a continuing challenge. Although infrequent, infection of a fermenter can be catastrophic for a manufacturer, and can also have a potential impact...

Background & Aims: Fungi are among the most important biological agents in air pollution. Textile factories are known as high risk places for contamination with fungal spores and metabolites. Since Yazd is one of the most important textile industry centers, this study was conducted to determine the concentration and types of airborne fungi in Yazd textile factories. Methods: A total of 235 indo...

A flameless atomic absorption method for the coextraction of platinum and palladium from biological and environmental samples by high molecular weight amine (HMWA) is given. Also, methods for lead determination in biological samples by use of extraction flameless analysis and direct aspiration-flame analysis are reported. A study of lead contamination of Vacutainer tubes is given.
