Microbiological community structure on logs used for groynes in a riverbank system

Abstract It is important for civil engineering applications to investigate resistance wood decay in aqueous environments. DNA from microorganisms inhabiting logs (groynes) that had been used about 15 years as a water control system prevent riverbank erosion was extracted and the microbial community structure examined. specimens four sections, above under water, ground bottom parts of were pulled out river. Then, barcode sequences detection fungi bacteria amplified each sample by polymerase chain reaction. Microbes identified nucleotide sequences, relationships between microbes environmental conditions discussed. The section significantly decayed, while slight strength loss observed other sections. white-rot basidiomycete Xeromphalina sp. detected suggesting this fungal species responsible significant study. Wood sections including not decayed even though fungus all logs, could degrade underground where oxygen supply limited.
