Denitrification Associated with Periphyton Communities [PDF]

open access: yesApplied 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

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

open access: yesPLoS 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 ...

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

open access: yesEcotoxicology 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 ...

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

open access: yesFrontiers 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.

Characteristics of stable nitrogen isotopes in particulate organic matter and periphyton of a subtropical Chinese watercourse, the Dashahe River

open access: yesKnowledge and Management of Aquatic Ecosystems, 2013
The stable nitrogen isotope ratios (δ15N) of particulate organic matter (POM) and periphyton were measured at sites along the Dashahe River, a short subtropical watercourse in SE China. δ15N values of both POM and periphyton

Desiccation and recovery of periphyton biomass and density in a subtropical lentic ecosystem - doi: 10.4025/actascibiolsci.v35i3.14022

open access: yesActa Scientiarum: Biological Sciences, 2013
This study assessed the desiccation effects on biomass and algal density of periphyton in a subtropical lentic ecosystem. This experiment was conducted with only one in situ experimental desiccation event for 15 hours in a mature periphytic community ...
