The characteristic of its degradation was researched and the results showed that the optimum conditions of this strain for degrading LAS were 30℃, pH 6.0, 150 ml solution in 500 ml triangle vase, 120 r/min, LAS concentration of 200 - 600 mg/L. The growth amount of the bacteria were up to 0. 443 ( OD400 ) and the degrading rate was up to 89.4%. The ability of the bacterium to degrade LAS could be as high as concentration of 1 200 mg/L.展开更多

MethodThe rice seeds were soaked in 0 (water as a control), 1, 2, 4 and 6 g/L fulvic acid (FA) before sowed. Then, the rice morphological indices, leaf chlorophyll content, photosynthesis parameters, root activity and chlorophyll fluorescence parameters were measured in the following field studies. ResultCompared with the control, the leaf area index, chlorophyll content, net photosynthetic rate, stomatal conductance and dry matter weight and some fluorescence parameters such as the maximum photochemical efficiency of photosystem II (PSII) (Fv/Fm), excitation energy capture efficiency of opened PSII reaction center (Fv’/Fm’) and efficiency of the open reaction centre (ΦPS II) increased by different levels at both jointing stage and heading stage of direct seeding rice, whose seeds were soaked by FA with different concentrations. High FA concentration (4-6 g/L) significantly increased the cultivated rice leaf area index, chlorophyll content, net photosynthetic rate, stomatal conductance, transpiration rate and dry matter weight by 10.32% -22.88% , 5.88% -13.11% , 12.16% -26.84% , 11.43% -88.46% , 10.63% -21.63% , 18.49% -19.68% , respectively, thereby improving the physiological function and light energy transform efficiency of rice at the growth stage. With FA concentration increasing, the yield, effective panicles, grain number per panicle and seed setting rate were increased significantly compared with the control by 17.52%-18.71%, 3.46%-3.85%, 6.30%- 6.51% and 7.82%-8.69% respectively. ConclusionSoaking rice seed with FA could be considered as an effective way to improve the rice competitiveness at early growth stage.展开更多

Method Ugifour-component condensation reaction was used to synthesize peptide mimic CPP32 inhibitors; ResultsA key isocyanide component (aspartate-derived isocyanide 3) and one of the designed CPP32inhibitors 4 (as a template) were synthesized; Conclusion The CPP32 inhibitor 4 was synthesized bythe newly developed procedure, which is an Ugi four-component condensation reaction based onaspartate-derived isocyanide 3. This method can be used to build up the CPP32 inhibitor library.展开更多

When Pd and Ag are electrodeposited together, more metals are gained in the same time, and the deposited Ag does not dissolve in this situation. The metals are electrodeposited completely at the potentials from -0.4 to -0.6 V(vs MSE) and the deposits contai-n Ag and PdHx. The electrodeposition of Pd can boost h-ydrogen evolution,and then the reaction between H;and NO_(2)^(-)is sped up, thereby lowering the concentration of NO_(2)^(-)and inhibiting the dissolution of Ag.展开更多

The germs have been separated from endosperm from 0 h (air-dry seed) up to 21 h in each 3 h after the start of seeds soaking. Cell nucleus have been allocated from germs and cleared, and then from them supramolecular-genome compartments were extracted by increasing ionic strength of solution. The Arg-X (tryptase) activity was assessed by cleavage of Arg-X bonds in the arginine-enriched protein protamine in all nuclear fractions. In the present study have shown what Arg-X protease-sensitives zones can be located on the supramolecular structures of chromatin matrix in processes of realization of ontogenetic programs of development in mature germs of the winter and transformed from it spring wheat. Arg-X protease-sensitive can translocate and coordinated in heteropolymer structures on the same genetic matrix. Questions of epigenetic mechanisms are discussed.展开更多
