A teeming life in the gutters

2015

A study reveals unexpected biodiversity in Parisian storm drains: 6,900 species of eukaryotes, including microalgae and fungi, could help treat rainwater and urban waste.

20170116_0010

Beneath the streets of Paris lies a teeming microbial life: 6,900 potential species of eukaryotes inhabit the storm drains, including diatoms, amoebas, alveolates, and rhizarians, as well as fungi, sponges, and mollusks. These communities, identified from about a hundred samples, could play a key role in treating rainwater and urban waste by contributing to the decomposition of certain solid wastes and other pollutants. An ecological approach to rethinking urban rainwater management.

Parisian gutters harbour an impressive variety of micro-organisms. Scientists have studied biodiversity in street gutters, and compared it to biodiversity in sources of non-potable water. They analysed around a hundred samples from locations throughout Paris, and found 6,900 potential eukaryote species. Much of this great biodiversity consists of microalgae in the diatom group, alongside other unicellular eukaryotes such as amoebas, alveolates and rhizari, as well as fungi, sponges and molluscs…
