Накратко на български

Микропластмасите (например PET) в отпадните води се изследват чрез използването на местни гъбички и микроорганизми. Това е важно, защото натрупаният пластмасов отпадък в природата представлява глобална заплаха за здравето на биосферата.

Removal of microplastics from the environment using autochthonous wastewater-derived microbial consortia

The accumulation of microplastics (MPs) in the environment poses a global health threat to the biosphere. Known and demonstrated conventional methodologies used in the treatment of MPs in wastewater have several limitations. Therefore, there is a need to develop new eco-friendly, cost-effective biobased MPs (Polyethylene terephthalate-PET) removal strategies. Microorganisms can transform organic matter as well as remove pollutants through a chain of different catabolic reactions energized by the induction of non-stereoselective enzymes. We would have accomplished most of the work packages as intended, but the decision to conclude the project before its full duration and completion affected this. While we completed WPs 1 and 2, WPs 3-6 were not adequately addressed due to time constraints. We were able to isolate and characterize microplastics in the wastewater in Granada, Spain, as well as the different fungal strains from the sludge. These activities comprised most of the tasks in WPs 1 and 2. In effect, the identification of key genes in the catabolic process, selection of microbial consortium with the ability to remove MPs, scaling up the process into a bench-scale bioreactor to develop a bioaugmentation technology with a microbial native consortium based on their ability to degrade MPs. and assessment of the toxicity of the resulting effluent after MPs process were part of the objectives not achieved. The training and transfer of knowledge were achieved basically due to the cross-fertilization of ideas and the improvised techniques/protocol developed during the isolation of MPs from sludge/wastewater. I benefitted immensely from the professional training and seminar presentation attended at the Institute of Water Research, University of Granada, Spain.

Цел на проекта

The accumulation of microplastics (MPs) in the environment poses a great threat to the biosphere. Known and demonstrated conventional methodologies used in the treatment of MPs in wastewater have several limitations. Therefore, there is the need to develop new eco-friendly, cost-effective biobased MPs (Polyethylene terephthalate-PET) removal strategies. Microorganisms can transform organic matter as well as remove pollutants through a chain of different catabolic reactions energized by the induction of non-stereoselective enzymes. Hence, this project will be the first attempt to deploy microbial autochthonous consortia as an eco-friendly remediation technique and strategy in the removal of MPs in the wastewaters. However, to overcome the limitations associated with cultivation and identification of MP degraders, I propose the use of a natural microbial consortium that harbours a plastic-degrading microbial community in wastewater after an enrichment process. Thus, in this project, an enhancement of microorganisms with catabolic capacity to transform MPs will be used for the development of a bio-based tailored technology, which represents the promising potential of this project. The overall objectives of this project are to: (1) characterize MPs in wastewater (2) isolate autochthonous consortium of MPs (PET) degraders in a short term enrichment experiment, study the microbial communities participating in MPs removal and identification of key genes in the catabolic process (3) select a microbial consortium with the ability to remove MPs and study of the fate of MPs in batch experiments (4) scale-up the process into a bench-scale bioreactor to develop a bioaugmentation technology with a microbial native consortium based on their ability to degrade MPs. (5) assess the toxicity of the resulting effluent after MPs process (6) verify the implementation and validate the design of the bioreactor, calculating the effectiveness of the equipment through a predictive model
