The life-cycle of methanogenic granular biofilms
Trego, Anna (NUI Galway, 2019-08-19)Anaerobic granules, sometimes referred to as methanogenic granules, underpin the sustainable treatment of wastewater in high-rate anaerobic bioreactors. They are spontaneously-forming self-immobilised biofilm aggregates ... -
Linking microbiology and performance of slow sand filters for wastewater treatment
Gibbs, Joseph (NUI Galway, 2018-10-08)Slow Sand Filtration (SSF) is biologically mediated method of water treatment dependent upon the natural development of a complex microbial community within the filter-bed. Due to increasing water scarcity worldwide, the ... -
Microbial community dynamics of farmed Atlantic salmon gill microbiomes during amoebic gill disease episodes
Birlanga, Victor B. (NUI Galway, 2022-06-14)Gill pathologies, especially the Amoebic Gill Disease (AGD), present one of the main health concerns for marine aquaculture worldwide. In Ireland alone, Atlantic salmon (Salmo salarL.) production in fish farms was 12,000 ... -
Microbial ecology of methanogenic sludge granulation and its application in the reduction of selenate and selenite
Mills, Simon (NUI Galway, 7-05-21)This thesis attempts to address some of the knowledge gaps in the literature around methanogenic granulation. Much existing research focuses on granulation of flocculent biomass up to the point at which satisfactory ... -
The microbial ecology of novel horizontal flow biofilm reactors (HFBRs) used to treat methane, hydrogen sulphide and ammonia contaminated airstreams at 10°C
Gerrity, Seán (2015-05-29)Ammonia (NH3), hydrogen sulphide (H2S) and methane (CH4) are three problematic gaseous emissions that are regularly encountered in agricultural, industrial and municipal waste sectors. Methane is an important greenhouse ... -
Pure culture, co-culture and whole ecosystem investigations of single anaerobes, partnerships and microbial communities in anaerobic digestion
O'Sullivan, Sarah (2017-10-20)Anaerobic digestion (AD) is a multi-stage process whereby biodegradable material is broken down by complex microbial consortia into renewable CH4 in the absence of oxygen during waste and wastewater treatment. Anaerobic ...
