You can register here The recurring epizootics of highly pathogenic avian influenza (HPAI) in France have been associated with changes in the epidemiological landscape such as higher frequency of detections in wild birds and introductions into backyard farms This highlights the need for a deeper understanding of the factors that drive the spread of HPAI we examined various farm and environmental variables around the 2022-2023 outbreak sites in France to unravel potential common traits among detected outbreaks including different species and production types the farm characteristics and variables related with their direct environment within a 2km radius were collected accounting for qualitative and quantitative variable clusters were identified using k-medoid partitioning algorithm A random forest analysis was further used to hierarchize the relative role of each variable in the clustering process to assess the importance of the farm structural and environmental conditions on the outbreak occurrence.To disentangle the impact of environmental factors from intrinsic herd characteristics using the whole dataset including the farm characteristics and environmental variables (first scenario); second accounting exclusively for the environmental variables (second scenario) farm variables such as farm type were crucial in the clustering process overpassing most of the environmental factors although the distance from "particular risk zones" and the coastline were also important the clusters obtained with the second scenario that counts only for the environmental variables Received: 06 Dec 2024; Accepted: 30 Apr 2025 Copyright: © 2025 BEN SALEM, Andraud, Bougeard, Allain, Salines, Thomas, Schmitz, Saint-Cyr, Fiore, Le Bouquin and Scoizec.

factory in northwestern France While the greenery suggests all is well in the Ploufragan commune near the Brittany coast the truth is that a plant for making cleaning products has left a mess The surrounding soil is saturated with toxic hydrocarbons – byproducts of the soap production Tackling such environmental damage is a priority for Dr Thomas Reichenauer under a research project that has received EU funding to investigate how microbes can be used to break down contaminants in soil and groundwater.The problem is pressing because poisonous substances in the soil can seep into plants senior scientist at the Austrian Institute of Technology in Vienna it will take decades – or hundreds of years – until nature breaks them down completely,’ he said The EU has an estimated 2.8 million contaminated sites ranging from old industrial zones to landfills Clean-up efforts vary across Member States with Germany and the Netherlands leading the way The groundwater dimension is all the more acute because of worsening climate change which threatens to cause increasingly severe droughts So even as groundwater becomes a more precious resource less may be available to drink if it contains industrial pollutants Reichenauer coordinates a project called MIBIREM that has received EU funding to speed up the process of decontaminating soil and groundwater by learning more about their microbiome – the collection of microorganisms in a particular environment The researchers are trying to figure out how microbes interact to break down three particular contaminants: cyanides hexachlorocyclohexane and petroleum hydrocarbons While cyanides and hexachlorocyclohexane are less prevalent they’re toxic enough to warrant developing technology for breaking them down The initiative began in October 2022 and runs until end-March 2027 The process by which microbes can be stimulated to ramp up their consumption of contaminants is called bioremediation who originally trained as a geneticist and plant physiologist ‘Bioremediation is eco-friendly as we don’t have to introduce any toxic or dangerous chemicals,’ he said There are other ways of removing pollutants from soil Plants have been studied as a potential method for removing heavy metals But few commercial ventures exist because the removal process – another form of bioremediation – is slow offers only a partial solution because it typically removes toxic substances by adding fewer from the outset MIBIREM will focus entirely on using microbes because they have the potential to be the fastest and most eco-friendly option The project ultimately wants to come up with bioremediation tools for different industrial spots across Europe researchers hope to identify particularly useful microbes and store them for later use MIBIREM is focused on developing technologies that can be used on-site sparing itself the hassle of excavating soil and transporting it Because the project targets mainly industrial spots treating soil in the original place is sometimes the only option In the case of the factory site in Ploufragan where soap was produced for almost half a century until the mid-1990s this would mean being able to treat the area without digging up the vegetation that has grown there since the buildings were demolished in 2017 ‘If you can show that it works in the fields then there is a good chance that it can be commercially applied later on,’ said Reichenauer The global market for microbial bioremediation was valued at around €42 million in 2021 It’s projected to grow to about €85 million by the end of the decade Reichenauer sought to soothe any concerns that people might have about altering the microbiome of soil to remove contaminants saying such changes are neither negative nor positive and occur in line with environmental influences regardless of any human intervention MIBIREM could help the EU meet targets set under a mission called “A Soil Deal for Europe” which seeks a transition towards healthy soils by 2030 The use of microbes for bioremediation has also been the focus of an EU-funded project called GREENER which is due to finish this August after four and a half years soil from a former machinery park was excavated and treated on-site where microbes were used to remove hydrocarbons microbes enabled the removal of heavy metals from the groundwater without extracting it ‘We are working with clients that have a contamination problem and assisting companies that are performing remediation of the site,’ said Rocío Barros ‘Better understanding the microbiome in the soil will be very important for improving technologies that address soil pollution.’ GREENER went beyond MIBIREM in one respect: trying to create energy during the bioremediation process By coupling energy generation with soil and wastewater cleaning GREENER sought to help diversify the EU’s power sources while removing pollutants from the environment The energy component involves the use of microbial fuel cells As microbes break down organic molecules like hydrocarbons chemical energy is converted into usable electrical energy Results on this front have been less than promising when it comes to ramping up such activity sustainability and toxicology research group at the University of Burgos in Spain ‘Not all of the microbial fuel cells have reached a good enough performance for scaling up,’ she said This aspect of the project highlights the risks involved in research and development and the importance of funding sources including the EU Some of the microbial fuel cells being used to treat water have shown potential ‘The use of the fuel cells with wetlands has been very good,’ said Barros Hoping that microbial fuel cells can be further advanced, she is now developing a film that could be added to them to improve electricity generation under a new EU-funded project – BIOSYSMO – that is a successor of sorts to GREENER and that runs for four years through August 2026.  (This article was updated on 21 July 2023 to add a reference in the final paragraph to a new EU research project in the field)   Research in this article was funded by the EU please
