Makerere-Uganda # CHAMPIONING PAH SOLUTIONS # Polyaromatic Hydrocarbons (PAHs), particularly phenanthrene and pyrene, pose grave environmental and public health threats. Traditional detection methods like Gas Chromatography-Mass Spectrometry (GC-MS) are precise but suffer from cost, time, and accessibility constraints, especially in resource-limited areas. Our research introduces a portable, cost-effective biosensor, aligning with the UN’s Sustainable Development Goal 14 (Life Below Water). This biosensor aims to protect aquatic life and ensure water resource sustainability.

RUBochum # Breaking β-Lactams - Biosensors for Antibiotics # Multidrug-resistant bacteria are one of the major threats to humans nowadays. These pathogens can result from misuse, overuse and improper disposal of antibiotics and can lead to higher health care costs, longer disease progression and higher mortality. To prevent the emergence of multiple antibiotic resistances, antibiotics must be detected and deactivated. Since beta-lactam antibiotics are among the most used antibiotics, we aim to detect them.

SCU-China # SRBioQuencher # Hydrogen sulfide(H2S) is a harmful gas in urban sewers, due to its toxicity, pungent odor, and flammability. Sulfate reducing bacteria (SRB), the main source of H2S in sewer, tend to resist the current chemical treatment once the biofilm formed. Here, we designed a predator, SRBioQuencher to kill SRB, thereby reducing the high H2S concentrations in sewers efficiently and safely. Cocktail therapy was applied by equipping SRBioQuencher with the ability to eliminate SRB biofilms by introduced glycosidases to degrade their main skeletons, inhibit the reformation of SRB biofilm by degrading the quorum sensing signal molecules, and kill SRB by the expressed antimicrobial peptides.

Stanford # Antibiotic Resistance Control (ARC): Engineering T7 Phages for Sub-Host Specificity # Antibiotics have long been the cornerstone of treating bacterial infections and, at times, are the only effective care option available. Rising antibiotic use in developing nations has rapidly reduced the effectiveness of conventional antibiotics and led to a rise in antibiotic resistant bacteria (ARB).
抗生物質は長い間、細菌感染症の治療の基軸であり、時には唯一の効果的な治療法でした。開発途上国での抗生物質の使用増加は、従来の抗生物質の効果を急速に低下させ、抗生物質耐性菌（ARB）の増加を引き起こしました。

Stockholm # LuciPEP: A bioluminescent biosensor for microplastic detection # The greatest threat to our aquatic ecosystems exists at a microscopic scale. Microplastics and nanoplastics are plastic particles that range from the nanometre scale up to 5mm. Almost everywhere scientists have looked they have found microplastics, yet only now are we beginning to understand the detrimental impact that they can have on our own health and that of ecosystems. Any solution relies on an understanding of the problem it is trying to tackle.

Stony-Brook # Nitroscillator: Engineering Sustainable Nitrogen-Fixing Bacteria with Genetic Oscillators # Nitrogen fertilizers are used to fulfill the food requirements of a growing, global population. However, due to the environmental repercussions of fertilizer synthesis and usage, an alternative is needed. We propose a sustainable biofertilizer design that replicates diazotrophs’ nitrogen-fixing ability while reducing environmental impact. Our approach involves introducing nitrogenase genes into an oscillatory genetic network in Escherichia coli and Pseudomonas protegens.

SUSTech-OCE # Air BioClean System # Indoor air pollution is a significant global health concern. To tackle this issue, our team utilized a microbial co-culture system and gene editing techniques to modify Escherichia coli strains. These modified E.coli strains can absorb and eliminate common indoor pollutants, such as formaldehyde, and also hydrogen sulfide. Moreover, they can produce distinct fluorescent signals to indicate the presence of pollutant concentrations that surpass safety standards.

TecMonterreyGDL # Building a FRET-based sensor for in vivo monitoring of emerging contaminants in water # In Mexico, water pollution affects over 50% of water bodies leaving millions of people without safe drinking water. Part of the problem are emerging contaminants such as pharmaceuticals and heavy metals. Due to their low concentrations, these have been historically ignored, however, due to recent studies, linking them to toxicity markers in living organisms, they are now recognized as a significant environmental threat.

Tsukuba # AMINO SHIP # Japan is surrounded by the sea, and most of its trade is dependent on marine transportation. The problem of marine biofouling has become an issue in this maritime transportation. Marine biofouling causes increased vessel weight and increased resistance to water currents as it adheres to vessel surfaces. This directly leads to increased fuel consumption, which in turn causes global warming, air pollution, and economic problems.
