Hussein Kanbar and Michael Holmboe has collaborated with EMG/UMU Prof. Göran Englund and PhD student Fredrik Olajos, on the faith of (ancient)DNA adsorbed onto minerals in 10,000 y old Swedish lake sediments. Their first publication is now available online at: doi.org/10.1016/j.apgeochem.2020.104728.
Highlights
- Lake sediment geochmemistry plays a significant role in the sorption.
- Clays were the main sedimentary components to host DNA.
- Both clay-mineral and organo-clay complexes govern the sorption of DNA.
- A DNA infrared fingerprint was determined in sediments via spectral subtraction.
- DNA-hotspots in lake sediments were revealed using geochemical approaches.
