Description of activities

The current research focus of the ten-member Laboratory Team, as reflected in their scientific publications over the past year, includes studies on:

– 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.
