Colonization of treated and untreated decking materials by bacteria, fungi and algae quantified by qPCR
2015 - IRG/WP 15-20568
The use of durable wood species for wood decking in outdoor applications, e.g. garden terrace (use class 3) is gaining more and more interest on the part of consumers and architects. To get detailed information on the practical use of deckings, a project was started in 2010. In total 71 different decking materials (0.03 m²) were installed and evaluated over 30 months. Beside other parameters, the...

Evaluating the role of Actinobacteria in the gut of wood-feeding termites (Reticulitermes spp.)
2017 - IRG/WP 17-10880
Nitrogen has been shown to be a limiting nutrient across a range of xylophagous insects. These insects often rely on symbiotic microorganisms in the gut for nitrogen acquisition, via fixation of atmospheric nitrogen or break down of other available nitrogenous substances. In phylogenetically lower, wood-feeding termites, the role of nitrogen fixing bacteria has been well studied. However, there is...

Analysis of hindgut bacterial phyla frequency and diversity in subterranean termites exposed to chitosan-treated wood
2017 - IRG/WP 17-10882
The termite hindgut contains a microbial community that symbiotically aids in digestion of lignocellulosic materials. For better understanding of the dynamics of the bacteria-termite relationship, a species survey of bacterial hindgut microbes in subterranean termites (Reticulitermes flavipes: Kollar) collected from Louisville, Mississippi was performed after exposure to chitosan-treated and contr...

Assessment of the quality and lifetime of wooden pile foundations
2017 - IRG/WP 17-10883
The development of wooden pile foundations started centuries ago and enable man to build and live in strategic and fertile areas. Although the building methods, the building materials and the building regulations chanced especially over the last decades, worldwide wooden pile foundations still fulfil their function to support above ground constructions of which many belong to our cultural heritage...

Imports of African logs, do they harbor wood-decaying alien fungi and bacteria that could become a potential threat at temperate latitudes? – First results
2018 - IRG/WP 18-10904
In this project we investigate the potential threat of alien wood-decaying fungal and bacterial species imported to Germany with logs from African countries. In a first approach we analysed fungal species on imported logs by identification of fruit bodies by DNA sequencing of the internal transcribed spacer (ITS) regions ITS1 and ITS2. First results revealed the existence of at least one alien fun...

The biodegradation of creosote oil by various species of white rot fungi and bacteria isolated from the contaminated soil
2018 - IRG/WP 18-50334
The aim of the study was to determine biodegradation effectiveness of the selected polycyclic aromatic hydrocarbons (PAHs) contained in creosote oil, by two white rot fungal species (Bjerkandera adusta and Irpex lacteus) and three bacterial species (Pseudomonas putida, Pseudomonas sp. OS4 and Rahnella aquatilis). Bacteria were isolated from the soil contaminated with petroleum hydrocarbons from th...
