Screening, identification, and low-energy ion modified breeding of a yeast strain producing high level of 3-hydroxypropionic acid

Abstract: 3-Hydroxypropionic acid (3HP) is an important platform chemical with a wide range of applications. The biological preparation of this compound is safe and low cost. In this study, orchard soil and human waste were used as raw materials to screen microbial strains that could produce 3HP in selective medium containing varying amounts of propionic acid. A yeast strain that can use propionic acid as substrate and produce 48.96 g/L 3HP was screened. Morphological observation, physiological and biochemical identification, and 26s rDNA sequencing identified the IS451 strain as Debaryomyces hansenii. The low-energy ion N+ , with the energy of 10 keV and a dose of 70 × 2.6 × 1013 ions/cm2 , was implanted into the IS451 strain. The mutant strain WT39, whose 3HP titer reached 62.42 g/L, was obtained. The strain exhibited genetic stability and tolerance to high concentrations of propionic acid and was considered to have broad application prospects.

Generation of Cluster-Type Entangled Coherent States via Cavity QED

Abstract: In this paper, we present a scheme for generating cluster-type entangled coherent states via cavity QED. The scheme is based on the off-resonant interaction between one atom and N cavities, so the spontaneous emission of the atom can be ignored. The initial states of the N cavities are all prepared in vacuum states. We also discuss the experimental feasibility.

The Effect of Hydraulic Load on Removal of COD and Ammounia-N from Municipal Wastewater by Using an Internal Loop Bioreactor with Ceramic Honeycomb Biocarriers

Abstract: Removal of COD and ammounia-N from municipal wastewater by using an internal loop bioreactor with ceramic honeycomb biocarriers is under study,and the article investigated the effect of hydraulic load on the pollutants removal efficiency and characteristics.The results demonstrated that the COD removal ratio was decreased by 31.90%as hydraulic load increased from 0.5m 3 /(m2.h)to 1.5m3/(m2.h),but the ammonia-N removal ratio was deceased by 70.92%under the same conditions;the removal ratio of COD was 37.99%when hydraulic load was 1m 3 /(m2.h),with a removal load of 1.85kg/(m3.d);the removal ratio of NH3-N was 44.15%,and the volumetric load of ammonia-N was 0.83kg/(m3.d).And the indicative microorganism on ceramic honeycomb biocarriers displays regular changes with the increase in hydraulic load from 0.5m 3 /(m2.h)to 1.5m3/(m2.h).

Preparation and Characterization of TiO₂ Nanowires Modified Organically with Coupling Agents.

Abstract: Anatase-type one-dimensional TiO₂ nanowire was prepared by hydrothermal method. The nanowires were modified by three kinds of silane coupling agents, such as KH550, KH560 and KH570. Flocculation was caused when the amount of modifier reached a certain level. When KH570 was used at 3.0 percent, at 80 °C, 4 h, and pH value between 9 and 10, modified nanowires had the highest 56.5 percent lipophilization degree, the lowest 0.562 per/nm² surface hydroxyl number, and the maximal 121.2° static contact angle.

Accurate multiconfiguration calculations of energy levels, lifetimes, and transition rates for Ge XIX

Abstract: Energy levels, radiative rates and lifetimes for electric-dipole (E1), electric-quadrupole (E2), magnetic-dipole (M1), magnetic-quadrupole (M2) transitions among the lowest 97 levels belonging to the 3s 2 3p 2 , 3s3p 3 , 3s 2 3p3d, 3s3p 2 3d, 3s 2 3d 2 , and 3p 4 configurations in silicon-like Ge XIX have been calculated through Multiconfiguration Dirac-Hartree-Fock method. High-accuracy calculations have been performed with accurate treatment of relativity, electron correlation, and quantum electrodynamic effects, as well as inter-electron correlation. The calculated energy levels are in excellent agreement with available experimental data. The present results are reported as benchmarks for future calculations and measurements.
