Description of activities
The topics currently undertaken by the ten-person team focus on research concerning:
– isotope composition of carbon and nitrogen in the organic matter of peat and sediments in the context of climate conditions reconstruction,
– biogas yield and methane fermentation,
– nitrogen transformations in the soil environment, especially denitrification,
– anaerobic decomposition of organic matter, especially focusing on the pathways of various organic acids which are precursors to methanogenesis,
– polymers such as lignin, cellulose, and hemicellulose originating from sediments and fossil wood of different ages and maturity stages,
– surface water studies – conducted in collaboration with Polish industry, mainly mining
Laboratory equipment
Thermo Scientific
Trace 1300 Gas Chromatograph
| Analyses of H2, CH4, CO2, O2, N2concentrations using the Carboxen 1010 Plot column and a thermal conductivity detector (TCD). |
| Analyses of C1-C9 hydrocarbon concentrations using an Alumina column and a flame-ionization detector (FID). |
Analytik Jena
Multi N/C 2100 Analyzer
| Analysis of total carbon (TC), total organic carbon (TOC) (two methods – differential and direct NPOC), total inorganic carbon (TIC). |
| Analysis of total nitrogen (TN) in liquid samples. |
Nordic ULT U100 Low-Temperature Freezer
| Designed for freezing solid and liquid samples within a temperature range of –60 to – 86°C. |
IKA RO 15 Multi-Position Digital Magnetic Stirrer
| Designed for synchronous stirring without heating. The stirrer allows simultaneous stirring of liquids at 15 positions with a maximum volume up to 0.4L at speeds ranging from 0 – 1200 rpm. |
WTW photoLab 6600 UV-VIS Photometer
| Photometer for chemical analyses using colorimetric methods. |
Biosan UVT-S-AR PCR Laminar Flow Cabinet
| The cabinet is designed for clean work with DNA samples that provides protection against contamination and is equipped with: |
| – a UV flow germicidal lamp that ensures continuous decontamination inside the chamber during operation, |
| – a UV recirculator containing a lamp, fan and dust filters placed in a special casing, ensuring that the user working inside is shielded from UV radiation, |
| – an automatic function that turns off the open UV lamp when the front window is raised. |
SARTORIUS Stedim Bioreactors
| Bioreactors (5L) – 3 pieces with a vertical stirrer and options for controlling temperature, pH, oxygen concentration, septum for gas sample collection, option to supply nutrients, and collect samples without opening the reactor. It comes with a control and data collecting module and a pressure sensor. Used in fermentation research. |
| Bioreactors (6pcs) of 1.5 L capacity with vertical stirrer and temperature control, with septum for gas sampling and pressure sensor. |
| 250 ml batch bioreactors with sampling septum. |
OHAUS SHR-2D Digital Shaker
| Designed for various applications requiring precision and repeatability such as cell cultures, chemical extractions, solution mixing, and solubility testing. |
| – reciprocating motion in both directions characterized by a stroke length of 19 mm, |
| – speed range from 20 to 300 rpm. |
