Autor: Sate Ahmad, Charilaos Yiotis, Weimu Xu, Jan Knappe, Laurence Gill, Jennifer McElwain

Publikováno v: Plant Direct, Vol 8, Iss 10, Pp n/a-n/a (2024)

Abstract Anthropogenic increase in carbon dioxide (CO2) affects plant physiology. Plant responses to elevated CO2 typically include: (1) enhanced photosynthesis and increased primary productivity due to carbon fertilization and (2) suppression of lea

GR2L: A robust dual-layer green roof water balance model to assess multifunctionality aspects under climate variability

Autor: Jan Knappe, Manfred van Afferden, Jan Friesen

Publikováno v: Frontiers in Climate, Vol 5 (2023)

Urban blue-green infrastructures (BGIs) fulfill a variety of functions that enable cities to cope with climate change and additional urban anthropogenic pressures such as increasing population density, heat island effects, biodiversity loss, and prog

Spatial Variation of the Microbial Community Structure of On-Site Soil Treatment Units in a Temperate Climate, and the Role of Pre-treatment of Domestic Effluent in the Development of the Biomat Community

Autor: Alejandro Javier Criado Monleon, Jan Knappe, Celia Somlai, Carolina Ospina Betancourth, Muhammad Ali, Thomas P. Curtis, Laurence William Gill

Publikováno v: Frontiers in Microbiology, Vol 13 (2022)

The growth of microbial mats or “biomats” has been identified as an essential component in the attenuation of pollutants within the soil treatment unit (STU) of conventional on-site wastewater treatment systems (OWTSs). This study aimed to charac

Response of the ubiquitous pelagic diatom Thalassiosira weissflogii to darkness and anoxia.

Autor: Anja Kamp, Peter Stief, Jan Knappe, Dirk de Beer

Publikováno v: PLoS ONE, Vol 8, Iss 12, p e82605 (2013)

Thalassiosira weissflogii, an abundant, nitrate-storing, bloom-forming diatom in the world's oceans, can use its intracellular nitrate pool for dissimilatory nitrate reduction to ammonium (DNRA) after sudden shifts to darkness and anoxia, most likely

Successful characterisation of on-site wastewater treatment system biomats using the Microbes of Activated Sludge and Anaerobic Digesters (MiDAS) taxonomic database

Autor: Alejandro Javier Criado Monleon, Jan Knappe, Celia Somlai, Carolina Ospina Betancourth, Muhammad Ali, Thomas P. Curtis, Laurence William Gill

There has been a large output of genomic data in ecological studies of centralised wastewater treatment plants over the past number of years. One significant collaboration of Danish and Swedish research institutions lead to the development of the Mic

Assessing the spatial and temporal variability of greenhouse gas emissions from different configurations of on-site wastewater treatment system using discrete and continuous gas flux measurement

Autor: Jan Knappe, Celia Somlai, Laurence W. Gill

Publikováno v: Biogeosciences, Vol 19, Pp 1067-1085 (2022)

Global emissions linked to wastewater treatment are estimated to account for up to 1.5 % of total greenhouse gas (GHG) emissions globally. However, few studies have measured GHG emissions from domestic on-site treatment systems (DWWTSs) directly. In

Volume 13
Issue 19

This research has used fluorescence spectroscopy and parallel factor analysis (PARAFAC) in order to characterize dissolved organic matter in septic tank effluent, as it passes through the biomat/biozone, infiltrating into the unsaturated zone beneath
