GXU-China # Microbial production of curcumin as a mildew-proof bio-pigment material. # Curcumin is a natural compound extracted from zingiberaceae, which has attracted worldwide attention because of its antioxidant, anticancer and mildew-proof functions. At present, the method of extracting curcumin from plants is squeezing and dissolving, which consumes a lot of energy and the output is far from meeting the market demand. At the same time, traditional mineral pigments are harmful to human body, while biological pigments are healthier.

NJTech-China-B # 1,5-PDO factory：Engineering Escherichia coli for the de novo production of 1,5-pentanediol # 1,5-Pentanediol (1,5-PDO) is one typical C5 diol commonly used as a building block for the production of polyurethane coating and have a broad market. Currently, commercial manufacture of 1,5-PDO entirely relies on petroleum feedstock, which is constrained by the limited accessible C5 petroleum feedstocks. In our work, we developed a cell factoryĀto produce 1,5-PDO from glucose in Escherichia coli through the synthetic biology tools.

WHU-China # CRISPReporter # CRISPReporter is a novel multi-level DNA memory device we designed in Escherichia coli that utilizes CRISPR-related technology. It can record the temporal order of the signal in DNA for a long duration. When required, the recorded information can be read out by simple molecular biological methods, such as qPCR.
CRISPReporterは、我々がEscherichia coli（大腸菌）で設計した、CRISPR関連技術を利用した新しい多段階のDNAメモリデバイスです。これは長期間にわたり、DNAの信号の時間順序を記録することができます。必要に応じて、記録された情報はqPCRのような単純な分子生物学的方法で読み出すことができます。

WLC-Milwaukee # The Dirt Detective: A bioavailable phosphorus sensor powered by E. coli # Agriculture is one of the biggest industries in Wisconsin, where our team is based, and the crops produced here go all over the world. One important component in agricultural success is soil composition. It is essential to have the appropriate nutrients in the soil for crops to grow and provide a maximal return. Our team has engineered Escherichia coli to sense bioavailable phosphate in soil and provide a colorimetric readout of concentration.

XHD-WuHan-Pro-China # A microplastic treatment device for performing functions of Escherichia coli # The sea, which is supposed to be clean and clear, is now covered by plastic garbage, and microplastics will endanger human safety with enrichment. In previous studies, we found that surface display technology can display PETase on the surface of engineering bacteria and degrade microplastics in the environment. In order to ensure that the engineering bacteria will not spread in the water, we referred to the content of the Lithuanian igem team in 2022 to express the cellulose-binding protein in the engineering bacteria, and then added the cellulose component to the microplastic treatment device to anchor the engineering bacteria in the microplastic treatment device to prevent biological pollution.
