Denitrification Associated with Periphyton Communities [PDF]

Applied and Environmental Microbiology, 1981
Scrapings of decomposing Cladophora sp. mats (periphyton) covering stream bed rocks produced N 2 O when incubated under N 2 plus 15% C 2 H 2 . Denitrification (N 2 O formation) was enhanced by NO

Effects of water temperature on summer periphyton biomass in shallow lakes: a pan-European mesocosm experiment [PDF]

, 2015
Periphyton communities play an important role in shallow lakes and are controlled by direct forces such as temperature, light, nutrients, and invertebrate grazing, but also indirectly by planktivorous fish predation.

Phosphorus and metals immobilization by periphyton in a shallow eutrophic reservoir

Acta Limnologica Brasiliensia, 2021
: Aim: This study evaluated and compared the changes in the Total Phosphorus (TP) and metals (Cd, Cu, Ni and Pb) contents and accumulation rates in the periphyton on different substrate types (PET and glass) in wet and dry periods in a shallow eutrophic

The response of bacterial community to UVB was significantly different between immature periphyton and mature periphyton, but not for physiological indicators

Ecotoxicology and Environmental Safety, 2022
Periphyton has important ecological functions. It can even exist in environments with strong ultraviolet radiation. However, knowledge of periphyton under ultraviolet is limited, which limits the understanding and application of periphyton in ...

The behavior of organic phosphorus under non-point source wastewater in the presence of phototrophic periphyton.

PLoS ONE, 2014
To understand the role of ubiquitous phototrophic periphyton in aquatic ecosystem on the biogeochemical cycling of organic phosphorus, the conversion and removal kinetic characteristics of organic phosphorus (Porg) such as adenosine triphosphate (ATP ...

Nutrient Exposure Alters Microbial Composition, Structure, and Mercury Methylating Activity in Periphyton in a Contaminated Watershed

Frontiers in Microbiology, 2021
The conversion of mercury (Hg) to monomethylmercury (MMHg) is a critical area of concern in global Hg cycling. Periphyton biofilms may harbor significant amounts of MMHg but little is known about the Hg-methylating potential of the periphyton microbiome.

Investigating periphyton biofilm response to changing phosphorus concentrations in UK rivers using within-river flumes [PDF]

, 2010
The excessive growth of benthic algal biofilms in UK rivers is a widespread problem, resulting in loss of plant communities and wider ecological damage.

Comparative algological and bacteriological examinations on biofilms developed on different substrata in a shallow soda lake [PDF]

, 2008
According to the European Water Framework Directives, benthic diatoms of lakes are a tool for ecological status assessment. In this study, we followed an integrative sample analysis approach, in order to find an appropriate substratum for the water ...
