The dynamics of polycyclic aromatic hydrocarbon (PAH) degradation in Sphagnum litters and the decomposition of the litters were investigated. PAH concentration decreased to approximately half of the initial concentration as Sphagnum litters decayed. The initial PAH concentration was 489.2 ± 72.2 ng

L-phenylalanine ammonia-lyase (PAL; EC 4.3.1.5) from Sphagnum magellanicum BRID. is inhibited by t-cinnamic acid in vitro only at relatively high doses. In contrast, p-coumaric acid does not display an inhibitory effect in a comparable concentration range. Sphagnum acid, an endogenous cinnamic acid
Photosynthetic responses, carbohydrate composition and invertase activity in fructan accumulating bryophytes (Porella platyphylla and Sphagnum flexuosum) under different environmental conditions (carbohydrate treatments, dark starvation, low temperature, desiccation).

Photosynthetic responses, the non-structural carbohydrate pool and its alterations, and the acid invertase activity under different environmental conditions in the fructan synthesising Porella platyphylla and Sphagnum flexuosum are discussed. Sucrose and fructan are the major soluble carbohydrates
Sphagnan--a pectin-like polymer isolated from Sphagnum moss can inhibit the growth of some typical food spoilage and food poisoning bacteria by lowering the pH.

OBJECTIVE
Investigate if the antibacterial effect of sphagnan, a pectin-like carbohydrate polymer extracted from Sphagnum moss, can be accounted for by its ability to lower the pH.
RESULTS
Antibacterial activity of sphagnan was assessed and compared to that of three other acids. Sphagnan in its acid

Northern peatlands play a crucial role in the global carbon balance, serving as a persistent sink for atmospheric CO2 and a global carbon store. Their most extensive type, Sphagnum-dominated acidic peatlands, is inhabited by microorganisms with poorly understood degradation capabilities. Here, we

Members of the phylum Planctomycetes are common inhabitants of boreal Sphagnum peat bogs and lichen-dominated tundra wetlands. These bacteria colonize both oxic and anoxic peat layers and reach the population size of 107 cells per gram of wet peat. The 16S rRNA gene sequences from planctomycetes

We report the use of a model system that examines the dynamics of biological energy availability in organic matter in a sphagnum peat potting mix critical to sustenance of microorganism-mediated biological control of pythium root rot, a soilborne plant disease caused by Pythium ultimum. The

Microbial diversity, numbers, and metabolic activities in Minnesota peatlands were investigated using a variety of microbial enrichment and enumeration procedures together with radioisotopic measurements of microbial degradative processes. Minnesota peatlands were shown to contain large microbial
