The invention discloses nitrous acid and ammonia nitrogen resistant nitrobacter (Nitrobacter sp.) TKz-YC01, the preservation number of the nitrous acid and ammonia nitrogen resistant nitrobacter (Nitrobacter sp.) TKz-YC01 is GDMCC No: 65729, the nitrous acid and ammonia nitrogen resistant nitrobacter (Nitrobacter sp.) TKz-YC01 has been preserved in Guangdong Microbial Culture Collection Center on March 7, 2025, is called GDMCC for short, has the preservation address of Nitrobacter sp., and is classified and named as Nitrobacter sp., and the preservation name of the nitrous acid and ammonia nitrogen resistant nitrobacter (Nitrobacter sp. TKz-YC01 is Nitrobacter sp. The nitrobacter can effectively degrade nitrite, cyanate and / or ammonium salt in water, and the nitrobacter can still effectively remove nitrogen under the impact of 30 mM ammonium salt (ammonium chloride) and 50 mM nitrite (sodium nitrite).

This application discloses a method for determining the content of zinc gluconate oral solution, belonging to the field of pharmaceutical quality testing technology. The method uses disodium ethylenediaminetetraacetate titration, adding ammonium fluoride and Eriochrome Black T indicator to an ammonium chloride buffer system. Titration continues until the solution changes from purple-red to blue-green and remains unchanged for 30 seconds. The zinc gluconate content is calculated based on the titration volume. This method eliminates interference from sample color and excipients, accurately determines the endpoint, and has demonstrated good specificity, precision, accuracy, and stability through experiments. It is suitable for determining the content of near-colorless samples, samples with deepened color, samples tested at high temperatures, and commercially available samples from different manufacturers. The method is simple to operate, low in cost, and can meet the routine quality control requirements of zinc gluconate oral solution.

The present application provides a bactericide for fracturing, comprising a solvent, a bactericidal liquid and a bactericidal microcapsule; a main material of a wall material of the microcapsule comprises urea-formaldehyde resin and chitosan in a mass ratio of (8-10):1; a main material of a core material of the microcapsule comprises chlorine dioxide, isothiazolinone, dodecyl dimethyl benzyl ammonium chloride and sophoramine in a mass ratio of (5-8):5:2:1; and a mass ratio of the main material of the core material to the main material of the wall material is 1:(1-2). Meanwhile, the present application also provides a preparation method of the bactericide, which is simple, easy to operate and suitable for industrial application.

The present invention describes an attractant formulation for blood-sucking mosquitoes, characterized by its non-unpleasant odor, composed of linalool (10-15% v / v), lactic acid (1-10% v / v), hexanoic acid (0.1-1% v / v), and ammonium chloride (0.1-1% v / v). Although linalool is traditionally a repellent, in combination with these compounds, it acts as a mosquito attractant. This formulation improves the user experience by eliminating strong, unpleasant odors, allowing its use inside homes. The formulation is incorporated into insect traps by means of a fan that diffuses the mixture. The trap is designed with a pyramidal chamber containing openings for mosquito entry, an adhesive material on the inner walls, and a mesh that prevents mosquitoes from being drawn into the fan.In field tests, the trap proved to be as effective as the standard BG-Sentinel trap, but with the advantage of being more accepted in indoor environments due to its pleasant olfactory profile, which improves its potential for use within homes.
