Abstract
Assessment of the abundance of fungi in environmental samples by quantitative PCR (qPCR) of community DNA is often a difficult task due to biases introduced during PCR amplification, resulting from the differences associated with length polymorphism and the varying number of copies of the rRNA operon among fungal species, the lack of specificity of the primers targeting the different regions of the rRNA operon, or their insufficient coverage of the fungal lineages. To overcome those limitations, it is crucial to test and select the specific primers sets which provide the more accurate approximation to the quantification of the targeted fungal populations in a given set of samples. Fungi are a significant fraction of the microbiota in wastewater treatment plants (WWTPs), but the activated sludge microbial communities comprise many other eukaryotic microorganisms whose molecular markers are often coamplified by primers initially designed as fungal-specific. Here, the use of the FungiQuant primer set is recommended for the quantification of fungal molecular markers (18S rRNA genes) by qPCR in activated sludge samples and the full protocol is described.
