Biofilms from a Brazilian water distribution system include filamentous fungi

Filamentous fungi in drinking water can block water pipes, can cause organoleptic biodeterioration, and are a source of pathogens. There are increasing reports of the involvement of the organisms in biofilms. This present study describes a sampling device that can be inserted directly into pipes within water distribution systems, allowing biofilm formation in situ. Calcofluor White M2R staining and fluorescent ...

Evaluation of antifungal activity of essential oils against potentially mycotox...

The antifungal activity of essential oils of fennel (Foeniculum vulgare Mill., Apiaceae), ginger (Zingiber officinale Roscoe, Zingiberaceae), mint (Mentha piperita L., Lamiaceae) and thyme (Thymus vulgaris L., Lamiaceae) was evaluated against mycotoxin producers Aspergillus flavus and A. parasiticus. High Resolution Gas Chromatography was applied to analyze chemical constituents of essential oils. The effect of...

Filamentous fungi in drinking water, particularly in relation to biofilm formation

The presence of filamentous fungi in drinking water has become an area worthy of investigation with various studies now being published. The problems associated with fungi include blockage of water pipes, organoleptic deterioration, pathogenic fungi and mycotoxins. Fungal biofilm formation is a less developed field of study. This paper updates the topic and introduces novel methods on fungal biofilm analysis, p...

Characterising filamentous fungal biofilm in drinking water distribution system...

Tese de doutoramento em Engenharia Química e Biológica ; A qualidade microbiológica de água de consumo tem sido uma das grandes preocupações de fornecedores governamentais e privados. Sistemas de distribuição de água são complexos ambientes onde algas, bactérias, fungos e protozoários cohabitam. Muitos destes microrganismos são patogenicos ao homem. Uma vez no sistema de distribuição, microorganimos podem ader...

Surface hydrophobicity of solid culture and water biofilm of filamentous fungi

In situ detection of fungal biofilms in a water distribution system, Alto do Cé...

Recent investigations on water microbiology have shown that most of the biomass present in the drinking water network is located at the pipe walls as biofilms. Biofilms are organized in highly efficient and stable ecosystems and can be viewed as a survival mechanism; this way of life can provide protection from chemical, biological or physical stresses. Moreover, biofilms play a major role in the accumulation, ...
