Summary Plant roots create specific microbial habitat in the soil – the rhizosphere. In this study, we characterized the rhizosphere microbiome of four host plant species to get insight into the impact of the host (host signature effect) on resident vs . active communities. Results show a distinct plant host specific signature found among wheat, maize, tomato and cucumber, based on the following three parameters: (i) each plan...

Summary Limited freshwater ( FW ) availability due to climate change and increasing global populations is driving agriculture in arid and semi‐arid regions to recycle vast quantities of water for irrigation. However, irrigation with treated wastewater ( TWW ), which contains dissolved organic matter, salts and microorganisms might alter soil microbial populations, and thus affect soil fertility. We characterized the effects of...

Summary Detailed analysis revealed fundamental differences between bacterial association with cucumber ( Cucumis sativus ) seeds and seedlings roots. Seed colonization by bacteria seems to result from passive encounter between bacteria, conveyed by imbibed soil solution, and the germinating seed. In accordance, the seed‐associated bacterial community composition directly reflected that of the germination medium and was charact...

Summary Bacterial community structure and physiochemical parameters were examined in a sedimentation basin of a zero‐discharge mariculture system. The system consisted of an intensively stocked fish basin from which water was recirculated through two separate treatment loops. Surface water from the basin was pumped over a trickling filter in one loop while bottom‐water was recirculated through a sedimentation basin followed by...
