This invention discloses a reagent for determining choline in serum and its usage method, relating to the field of in vitro diagnostic reagent technology. It comprises the following components: MOPS, polyether F-68, dimethyl sulfoxide, prolin 300, potassium chloride, lithium acetate, calcium acetate, sodium tetraborate, sodium chloride, and choline. This invention provides an electrode filling solution that can be directly used to measure serum choline content using an electrode method. This method requires no sample preparation, has a short detection time, and provides stable and reliable results, avoiding the instability of choline in serum. It is compatible with appropriate equipment for quantitative detection. It solves the problem of inaccurate results due to the easy decomposition of choline during storage and also provides a low-cost method for detecting choline with results equivalent to tandem mass spectrometry.

This invention discloses a method for alleviating bioclogging through the synergistic degradation of extracellular polymers by multiple enzymes, comprising: selecting freeze-dried *Pseudomonas aeruginosa* and reviving and culturing it to obtain bacterial solution a; expanding the reviving bacterial solution a and mixing it to obtain bacterial solution b; re-inoculating bacterial solution b into a new culture medium until the logarithmic growth phase to obtain bacterial solution c; centrifuging bacterial solution c in the logarithmic growth phase and adding MOPS buffer solution to the precipitate to obtain a bacterial suspension; preparing a compound enzyme agent and adding the prepared compound enzyme agent to the bacterial suspension to react and decompose the extracellular polymers secreted by the microorganisms, thereby solving the clogging problem. This invention can alleviate the formation of bioclogging without affecting the water quality of reinjected water. Compared with single enzymes or combinations of two enzymes, it has advantages such as lower dosage, lower cost, better effect, and faster results.
