Light structures phototroph, bacterial and fungal communities at the soil surface [PDF]

open access: yes, 2013
The upper few millimeters of soil harbour photosynthetic microbial communities that are structurally distinct from those of underlying bulk soil due to the presence of light. Previous studies in arid zones have demonstrated functional importance of these

Anoxic phosphorus removal by denitrifying heterotrophic bacteria

open access: yesWater Science and Technology, 2003
The unexplained occurrence of anoxic phosphorus (P) accumulation has largely hampered modeling of nitrification denitrification biological excess P removal (NDBEPR) systems. The aim of this study was, therefore, to isolate and identify denitrifying - P accumulating heterotrophic bacteria (DPBs) from a NDBEPR system in order to evaluate anoxic P ...
