SYLVA expands eDNA research at Šiauliai Academy
2024-09-23

On 20 September 2024, the SYLVA project commenced a new phase of environmental DNA (eDNA) research, involving the collection of bioaerosol samples at Šiauliai Academy. Following the successful deployment of a high-volume air sampling device by BioSence in Novi Sad, Serbia, Vilnius University purchased a Precision Air device (from Univerzal komerc d.o.o.), which has now been installed at the Šiauliai Academy.

The purpose of this high-volume air sampler is to facilitate a deeper understanding of bioaerosols - airborne particles containing biological materials such as bacteria, pollen, and fungi. These particles have significant ecological and environmental implications, and their study can offer insights into the composition, sources, and dispersion of microorganisms in the atmosphere. From the sampled bioaerosols, researchers can extract environmental DNA to study biodiversity, track invasive species, and monitor environmental changes over time.

The installation of the Precision Air device at Šiauliai Academy strengthens SYLVA's research infrastructure. The air sampler allows for more efficient collection of bioaerosols, enabling the capture of a broader range of particles, including rare or less abundant organisms.

By complementing the existing research infrastructure, SYLVA enhances its capacity for advanced environmental research. The eDNA data generated from this sampling effort will contribute to improving bioaerosol dispersion models and facilitate a broader understanding of the ecological and atmospheric roles of bioaerosols. Through this research, the SYLVA project aims to provide a foundation for future studies in biodiversity and environmental monitoring.

eDNA sampling starts in Novi Sad
2024-04-02

A high-volume air sampler has been installed at the BioSense Institute in Novi Sad, Serbia. Its purpose is to collect total suspended particulate matter from the ambient air without selecting for specific particle sizes. The vacuum motor pulls air onto the 1.6-micron glass fiber filter at a flow rate of 80-100 cubic meters per hour over a constant sampling period. The filter is then analysed to determine the identity of the particulates through environmental DNA (eDNA) sequencing.

SYLVA is developing the first end-to-end protocol for affordable sampling and identification of airborne bioaerosols using Nanopore's 3rd generation eDNA sequencing technology: an ultimate method to identify the entire spectrum of bioaerosols, including those undetectable by other instruments.

The sampler is custom made by BioSense in collaboration with the Finnish Meteorological Institute.
