Microbial community dynamics in denitrifying biofilters receiving agricultural drainage
… in 2007 to determine how total and denitrifying bacterial communities varied by depth, transect, and position along a transect. Second, in our temporal study we sampled three biofilters over two years, January 2009 – December 2010, to determine how total bacterial, denitrifying bacterial, and …

Detection, Activity Measurement and Phylogeny of Ureolytic Bacteria Isolated from Elasmobranch Tissue
… 16S rRNA gene phylogeny indicated bacteria community structure in both elasmobranchs were under phylum Proteobacteria, Firmicutes and Actinobacteria. By conducting split-plot ANOVA, we found the microbial richness is significantly different (P=0.0814) between two superorders of …

Impact of Spatial Distance and Pollinators on Floral and Fruit Bacterial Communities of Solanum carolinense
… fitness. This dissertation examines how fruit bacterial communities, as determined using the 16S rRNA gene marker, are shaped across spatial and environmental gradients and the role of pollinators in shaping floral bacterial communities among natural populations of Solanum carolinense. There …

OXYHYH20-Integrated Renewable Hydrogen and Oxygen Production for Reduced Emissions in Wastewater Treatment Plant Operations
… oxygen concentration was shown to influence bacteria respiration and oxygen uptake rate (OUR) values increased proportionally at DO concentrations between 1 to 8 mg/L. The activity of certain enzymes, linked to the biodegradation process, such as protease and glucosidase, increased at higher …

Impacts of artisanal and large scale gold mining on tropical rivers in West Africa: A case study from the Brong Ahafo Region of Ghana
… on riverine ecology, particularly at biota community levels, remains understudied. This study investigated the impacts of ASGM on the ecology of the Surow River and that of an LSM (the Ahafo mine) on the Subri River between February 2013 and April 2014. Both the Surow and Subri rivers are …

Microbial diversity and activity in temperate forest and grassland ecosystems
… of the critical role played by the microbial community in ecosystem functioning. This relationship is supposed to be relevant for narrow processes, regulated by a restricted group of microorganisms, such as the nitrification process. This PhD thesis aimed at studying ammonia oxidizing bacteria …
