| Projekt bude sledovat chování sady biodegradabilních polyesterů v půdě. Ačkoli jsou tyto materiály chemicky podobné je jich osud v půdě diametrálně odlišný. Soustředíme se na kontrolovanou přípravu vzorků těchto materiálů a podrobné sledování jejich chování v půdě pomocí sady metod včetně izolace DNA a sekvenace a analýzy půdního mikrobiomu. | |

| The project will monitor the behavior of a set of biodegradable polyesters in soil. Although these materials are chemically similar, their fate in soil is diametrically different. We will focus on the controlled preparation of samples of these materials and the detailed monitoring of their behavior in soil using a set of methods, including DNA isolation and sequencing, as well as analysis of the soil microbiome.
