Research Interests

Dr. Guiomar Garcia-Cabellos is a graduate of the Universidad Autonoma of Madrid (Spain) where she completed her undergraduate studies in General Biology. Her PhD. in the Institute of Technology Carlow, under the supervision of Dr David Dowling, focused in the area of interactions between plants and microbes for improved bioremediation using constructed wetlands. She studied the endophytic and exophytic bacterial population of one particular plant commonly used in wetlands, Iris pseudacorus and the ability of these bacteria to breakdown pollutants. Furthermore, she gained strong experience in the science of working with endophytic strains, from their isolation from different parts of plants to their re-inoculation techniques, so as to prove that a particular bacterial strain can offer phytoprotection against specific heavy metals and organic pollutants. Her current research interests include the bioremediation of environmental pollutants including landfill leachate and TBT, Investigations in to the presence of Lithium and other metals in the fresh water systems and novel gene transfer systems in commercially important crops.

  • Christopher Finnegan:  “Bioremediation of Tributyltin (TBT) in Irish marine sediments: Microbial screening and process optimisation”. Dr. Guiomar Garcia-Cabellos (PI) Dr Anne-Marie Enright (CIT) and Dr David Ryan (CIT).  The aim of the study is to assess the ability of a range of microbial species isolated from sediment and soil to degrade TBT into its less toxic species dibutyltin (DBT) monobutyltin (MBT) and nontoxic inorganic tin (Sn4+). Assays used to screen isolates highlighted six candidate strains which were identified based on biochemical characteristics and 16S rRNA gene sequence analysis and used in a biodegradation assays. The samples were further analysed by gas chromatography mass spectrometry, which accurately measured and identified TBT and differentiated between degradation products (DBT and MBT). Results showed a maximum decrease of ≥70% TBT in liquid samples recovered from batch assays. Furthermore, the phytoremediation capacity of barley and oilseed rape (Hordeum vulgare, Brassica napus) was investigated to assess the ability of inoculated with candidate strains and none inoculate seedlings to enhance degradation of TBT in sediment and soil. This research has the potential to produce a commercial product to degrade TBT in sediment and soil and would be of great significance to the field of bioremediation and waste management.
  • Laurence Kavanagh:  “Comparative Hydrogeochemistry: Distribution of Metal Ions in Ground Water, Surface Water, Soils and Plants in the South East of Ireland”.  Dr. John Clary(PI), Dr Guiomar Garcia-Cabellos (CIT), Mr Jerome Keohane (CIT) and Dr Andrew Lloyd (CIT).  Comparative Hydrogeochemistry, the distribution of metal ions (x10) focusing on lithium in the soils, plants and waters of the South East of Ireland. And an investigation into the suitability of several endemic plant species and their ability to hyperaccumulate lithium in their tissues. the aim being to create a lithium bio-ore from the plants after their energy has been recovered.
  • Aisling Dunne: “Investigating the novel bacterium Ensifer adhaerans OV14 the putative replacement for Agrobacterium mediated gene transfer in commercially viable crops.”, Dr Guiomar Garcia-Cabellos, Dr David Ryan, Dr Ewen Mullins (Teagasc) and Dr Anne-Marie Enright (PI). This project aims to elucidate the soil dwelling bacterium Ensifer adhaerans OV14s, stereo-chemical interactions with plants and assessing its rate of colonisation using commercially viable crops (oilseed rape, peas and Arabidopsis ).  Challenging the bacterial colonisation rate in completely non-sterile conditions.  Utilising the process of gfp tagging OV14 and cryostat sampling of crops to provide fluorescent confirmation on endophytic or epiphytic colonisation.
  • Sinead Morris: “Microbial bioremediation and physiochemical treatment of landfill leachate” Dr Guiomar Garcia-Cabellos (CIT) Dr Deirdre Enright (ITT), Dr David Ryan(CIT ),  and Dr Anne-Marie Enright (PI). This project aims to deal with the treatment of Landfill leachate from Municipal Solid Waste landfills, a major drawback of this waste management system within Ireland.   The main objectives of this research is microbial biodegradation and physical adsorption of leachate constituents and aims to develop a cost effective treatment option for LFL based on combining treatments, which could be suitable for implementation on-site in landfills.
  • Wojciech Nowak : “Plant Growth Promotion potential of novel bacterium Ensifer adhaerens OV14”, Dr Guiomar Garcia-Cabellos, Dr David Ryan, Dr Ewen Mullins (Teagasc) and Dr Anne-Marie Enright (PI) Dr David Ryan (CIT). Current agricultural practice is reliant on unsustainable use of chemical fertilizers. One possible alternative is the use of a bio-fertilizer instead of/together with chemical fertilizers. This research aims to investigate the plant growth promotion potential of a novel bacterium Ensifer adhaerens OV14, with possible development of an OV14 based bio-fertilizer inoculum.
