The genetically engineered bacterium provided by the invention can catalyze L-phenylalanine to prepare benzoic acid. A new efficient benzoic acid synthesis path is introduced into the genetically engineered bacterium, a regeneration cycle of cofactors is formed by NADH oxidase, mandelic acid dehydrogenase and benzaldehyde dehydrogenase, the substrate conversion efficiency is improved, L-phenylalanine can be efficiently converted into L-phenylglycine, and the method is a green biosynthesis technology with wide application prospects.

Method and system for evaluating influence of blasting on anchoring support

The invention provides a method and system for evaluating the influence of blasting on anchoring support. Data monitoring points are arranged on a head-on section and a support section in the roadway tunneling process, the radius of a blasting funnel and the surrounding rock damage range of an anchoring support area are obtained, and the influence rate of the blasting surrounding rock damage range is calculated; obtaining a blasting area rock mass wave velocity and an anchoring support area rock mass wave velocity during blasting so as to calculate a blasting rock mass wave velocity influence rate; obtaining stress peak values before and after blasting of surrounding rock of the anchoring support area and corresponding stress peak value displacement values to calculate a stress peak value displacement transfer rate of the anchoring support area; measuring the distance between the blasting area and the anchoring supporting area and the supporting section displacement of the anchoring supporting ...

Fabricated building board room capable of being quickly built and building method of fabricated building board room

According to the assembly type building board room capable of being rapidly built and the building method thereof, fixing grooves in the bottom ends of U-shaped board boards are aligned with positioning columns and positioning grooves to be put down, the bottom ends of the U-shaped board boards enter containing grooves, meanwhile, the positioning columns stretch into the fixing grooves, the cross sections of the fixing grooves are in an inverted T shape, the positioning columns enter vertical grooves of the T-shaped fixing grooves at the moment, and the U-shaped board boards are placed in the containing grooves; the U-shaped house plates are fixed and limited in the horizontal direction, the situation of toppling is avoided, meanwhile, the protective heat preservation cloth is arranged at the openings in the two sides of the U-shaped house plates, a temporary house assembly type building can be rapidly built and is more stable than an open tent, meanwhile, the building time is saved, and ...
