The degradation of polyaromatic hydrocarbons (PAH) in an aged creosote-contaminated soil in the presence of Salix viminalis was investigated in a greenhouse experiment. Phenanthrene and pyrene were degraded 100% and 80%, respectively, in the presence of plants but only 68% and 63% without plants. The effects of the nonionic surfactant Triton X-100 or the addition of straw, without plants, were also studied.

Article Synopsis
- Paper mills processing recycled paper experience biofouling issues, impacting both operations and end products, which necessitate a deeper understanding of their bacterial communities.
- The study utilized DNA-based methods to analyze bacterial community structures in process water and biofilms across different mill locations, revealing unique compositions for each while observing common dominant patterns.
- Significant findings included that biofilms from the paper machine differed the most from other samples, along with the identification of numerous bacterial phyla, including known biofouling organisms, indicating that these bacteria are likely part of the natural microbiome of paper mills and could lead to the discovery of new bacterial species.
The interactions between two plant growth-promoting rhizobacteria (PGPR, Pseudomonas fluorescens SBW25 and Paenibacillus brasilensis PB177), two arbuscular mycorrhizal (AM) fungi (Glomus mosseae and Glomus intraradices) and one pathogenic fungus (Microdochium nivale) were investigated on winter wheat (Triticum aestivum cultivar Tarso) in a greenhouse trial. PB177, but not SBW25, had strong inhibitory effects on M. nivale in dual culture plate assays.
