Cadaverine is a critical C5 monomer for the production of polyamides. Pyridoxal 5′-phosphate (PLP), as crucial cofactor key enzyme lysine decarboxylase in cadaverine biosynthesis pathway, has seen persistent shortage, leading to limitations production. To address this issue, dual-pathway strategy was implemented, synergistically enhancing both endogenous and heterologous PLP synthesis modules resulting improved synthesis. Subsequently, growth-stage-dependent molecular switch introduced...
Cadaverine is a fundamental C5 building block in the production of polyamides. Due to limited regeneration efficiency intracellular pyridoxal 5'-phosphate (PLP), current fermentation-based cadaverine exhibits low efficiency. In this study, we developed an
In the present investigation, bio-inorganic composite, which was synthesized with chitosan and hydroxyapatite by adding zinc(II) ions, have been prepared precipitation method characterized Fourier Transform infrared (FTIR) spectroscopy energy dispersive X-ray analyzer (EDXA). Then, composite used for removal of Cobalt(II) from synthetic aqueous solution. The effects initial pH, contact time, kinetic isothermal adsorption were studied in detail using batch at different temperature. results...
Hydroxyapatite coating was prepared on titanium substrate by pulsed electrochemical technology, in which the Ca/P ratio 1.67 and pH adjusted dilute HNO3 NH4OH to 6.0.The X-ray diffraction, Fourier transform infrared spectroscopy scanning electron microscopy were used investigate microstructure morphology of materials.Then, effects hydroxyapatite MC3T3-E1 osteoblastic cells investigated MTT assay method evaluate cytocompatibility new scaffold.Results indicate that has great potential be as...
This paper introduced the preparation of butylene fipronil-loaded microcapsules with oppositely charged chitosan and sodium lignosulfonate as shell materials. It summed up performance, methods sketched application status layer-by-layer self-assembly. The whole progress was controlled by measuring change Zeta potential morphology characterized microscope SEM. Entrapment efficiency slow release performance microcapsule were determined measurement index. results experiment showed that surface...
We previously determined that the cyclase inhibitor tripropylamine (TPA) significantly enhances lycopene accumulation in Blakeslea trispora . To elucidate mechanism of TPA-enhanced accumulation, untargeted metabolome B. treated with TPA was analyzed by UHPLC-Q-TOF/MS. Forty-two differential metabolites were identified, which 15 meeting following parameters screened: variable importance for projection > 1, P < 0.05, and fold change 1.5. The down-regulated mainly cyclic...
The mechanical properties and microstructure of plastic mould steel with the martensite bainite–martensite (B/M) were investigated in detail. results show that air-cooled B/M possesses a better combination strength toughness compared water-quenched full after tempering within some intermediate temperature range. A mixed retards softening during also tempered embrittlement onset temperature. stable retained austenite (SRA) improved at

The drawing process of a high strength steel part without blank holder force was numerically simulated based on Dynaform. In present investigation, the velocity and profile motion punch studied by simulating operation part. results show that restricting controlling could all reduce spring back. measure non-pressure forming back about 31% Trapezoidal mode is most beneficial to
In this work, Numerical simulations based on finite element method have been carried out to study the effect of important process parameters formability AA5182 alloy sheets. The blank holder force between 0.5KN and 3KN friction coefficient(μ) 0.05 0.20, which resulted in successful drawing, was evaluated. Maximum percentage thinning has always obtained at conjunction corner bottom. maximum rate nearly 20% for a 3KN. Friction coefficient are shown that as increasing, becomes larger low is...
