The application provides a method for removing acetaminophen by using molybdenum powder to strengthen trivalent iron / tripolyphosphate activated molecular oxygen, in particular, molybdenum powder is used to reduce trivalent iron into divalent iron, and the divalent iron and the tripolyphosphate are used to activate molecular oxygen to remove acetaminophen. The addition of molybdenum powder has obvious advantages for trivalent iron / tripolyphosphate activated molecular oxygen, and the removal rate is greatly improved compared with the case without molybdenum powder, and the treatment efficiency of pollutants is improved. The presence of tripolyphosphate can avoid the precipitation of trivalent iron and divalent iron, and can also strengthen the activation of molecular oxygen. Under the condition of medium alkalinity, the system has strong removal capacity for acetaminophen. The morphology of molybdenum powder before and after the reaction and the cycle experiment show that the molybdenum powder has strong stability in the trivalent iron / tripolyphosphate system and can be reused.

The invention discloses application of polyphosphate kinase BsPPK in synthesis of ATP (adenosine triphosphate). The amino acid sequence of the polyphosphate kinase BsPPK is as shown in SEQ ID NO. 1. In specific application, adenosine diphosphate or adenosine monophosphate is used as a phosphate receptor, polyphosphate is used as a phosphoric acid donor, and ATP is synthesized under the action of polyphosphate kinase BsPPK. The polyphosphate is selected from tripolyphosphate or hexametaphosphate. The invention also discloses an application of the polyphosphate kinase BsPPK in the synthesis of uridine diphosphate-galactose, and an application of the polyphosphate kinase BsPPK in the synthesis of lactosyl-N-tetrasaccharide. According to the method, the ATP is synthesized and regenerated by utilizing the polyphosphate kinase BsPPK, so that the reaction cost of UDP-Gal and LNT in-vitro synthesis routes is greatly reduced. The method has important significance on ATP regeneration and synthesis of UDP-Gal and galactosyl lactose derivatives, and has a wide application prospect.
