The invention relates to the technical field of biology, in particular to 3D printing bio-ink and a preparation method and application thereof. The 3D printing bio-ink provided by the invention has good printability, biocompatibility and cascade metabolism function promotion effect, can be applied to rapid construction of a double-bacterium cascade degradation triclocarban engineering living body material which is high in bacterium content, stable in long-term operation and capable of efficiently degrading triclocarban (TCC), and is further applied to environmental restoration. The construction scheme of the artificial microbial community is widened, and a new thought is provided for environmental microbial remediation.

This invention relates to the field of catalyst technology, specifically to a single-atom iron-anchored hollow tubular carbon nitride catalyst, its preparation method, and its applications. This invention achieves atom-level dispersion and stable anchoring of iron through a multi-step synergistic strategy involving the construction of a hollow tubular support, the introduction of nitrogen vacancies, surface functionalization modification, and iron-imidazolium coordination vacuum impregnation followed by segmented heat treatment. The catalyst exhibits excellent performance in activating persulfate under near-neutral conditions, achieving a 98.2% removal rate of triclocarban (a typical pollutant) and a 65.4% removal rate of total organic carbon within 60 minutes, with extremely low iron leaching. It combines high activity, excellent stability, and environmental compatibility, providing a highly efficient solution for advanced water treatment.

The invention discloses preparation and application of a vector for expressing a triclocarban nano-antibody in lettuce, the vector comprises a recombinant vector PBI121-EGFP-dTCC-9 of a dTCC-9-VHH triclocarban bivalent nano-antibody, a plant is used as an efficient platform for expressing recombinant protein, the triclocarban nano-antibody is expressed, and the expression amount of the triclocarban nano-antibody is increased. A protein immunoblotting method and a fluorescence microscope observation method are used for determining that the recombinant protein is successfully expressed in the lettuce, the time required for successful expression is short (3d), and an important foundation is laid for obtaining a large number of antibodies from the lettuce. According to the invention, plasmids containing a target protein are transferred into plant cells so as to obtain transient controllable expression of the gene in the plant cells. Compared with stable expression, homeopathic expression does not need a complex step of integrating an exogenous gene into a host chromosome, the required time is short, and an expected result can be obtained within 3-4 days.

The invention discloses a bacteriostatic agent and a preparation method thereof, and the bacteriostatic agent comprises the following components: triclocarban, 2, 4-dichlorobenzyl alcohol, 18-crown-6, a surfactant and a solvent. According to the bacteriostatic agent, efficient and non-toxic triclocarban is used as a main bactericide, 2, 4-dichlorobenzyl alcohol and 18-crown-6 are compounded to improve the bacteriostatic effect, and the bacteriostatic agent has a good inhibition effect on staphylococcus aureus, escherichia coli, candida albicans and pseudomonas aeruginosa.

This utility model discloses a triclocarban production apparatus, relating to the field of triclocarban production technology. The inlet of the reactor is connected via pipelines to a p-chloroaniline tank, a 3,4,4'-trichloroisocyanuric acid tank, a first solvent tank, and a catalyst tank. The outlet of the reactor is connected via pipelines to a filter. The liquid phase outlet of the filter is connected via pipelines to a precipitation tank. The inlet of the precipitation tank is connected via pipelines to a saturated sodium carbonate solution tank. The outlet of the precipitation tank is connected via pipelines to a first centrifuge. The solid phase outlet of the first centrifuge is connected via pipelines to a crude product tank. After the p-chloroaniline reacts with 3,4,4'-trichloroisocyanuric acid, the catalyst is removed. Then, under the action of the saturated sodium carbonate solution, triclocarban precipitates out. The first centrifuge separates the solid and liquid phases after precipitation, obtaining crude triclocarban, which is then transported to the crude product tank. The obtained product has high purity and is environmentally friendly.
