In order to effectively improve junior high school students abilities in all aspects. This article is mainly based on the angle of moral and rule of law teaching innovation, aiming at the topic-based teaching method, deeply innovating the teaching activities of moral and rule of law in junior middle schools, aiming at effectively improving the teaching effect of moral and rule of law, and cultivating students comprehensive quality.展开更多

Itsmorphology, physiological and biochemical properties, cellwall pattern and G+C mol% content of DNA molecules were characterized. The 16S rRNA gene of strain PYX-6 wassequenced and analyzed for similarities to related bacterial species. Results indicated that strain PYX-6 is a member of the Genus Saccharothrix, and the strain was namedSaccharothrix sp. PYX-6. When pyrene was the sole carbon source in cultural medium, the strain PYX-6 assimilatedpyrene for growth and 0.005% of yeast extract stimulatedpyrene degradation and assimilation. The optimal pH ofcultural medium and the optimal shaking frequency during cultivation were 6—8 and 200 r/m, respectively. It was found that the disappearance of pyrene in medium occurred before significant growth of strain PYX-6 took place. Phthalic acid, benzylacetic acid, and benzylpropenoic acid were detected as catabolic intermediates during pyrene degradation with mass spectroscopy and this result indicated that Saccharothrix sp. PYX-6 adopted a pathway that is different from the pathway of the previously reported pyrene-degrading Mycobacteriumsp. PYR-1.展开更多
