厌氧复合菌群JZ-1降解拟除虫菊酯的特性和组成多样性研究

从农药厂废水中分离到能够降解多种拟除虫菊酯的复合菌群JZ-1,对该菌群降解特性研究结果表明,最佳降解条件为pH7、温度30℃;在最佳条件下培养15d,对100mg·L-1甲氰菊酯、氟氯氰菊酯、氯氰菊酯的降解率分别为53.27%、33.36%、41.39%。对该菌群的16S rDNA进行扩增和RFLP及测序分析结果表明,该菌群含有丰富的细菌资源,该菌群的优势种群包括红假单胞菌属（Rhodopseudomonas）和紫单孢菌科细菌（Porphyromonadaceae bacterium）。该研究为拟除虫菊酯的降解菌资源的挖掘和利用提供了理论参考。

Cultivar identification using 18S–28S rDNA intergenic spacer-RFLP in pomegranate (Punica granatum L.)

Since pomegranate is a fruit tree species showing high plant diversity, molecular techniques are required to quickly and precisely characterize and certify different cultivated varieties. The study evaluates a genetic method to identify pomegranate cultivars. The procedure is based on the Restriction Fragment Length Polymorphisms (RFLP) and Polymerase Chain Reaction (PCR) techniques. Ten pomegranate accessions from the varietal groups Mollar de Elche, Mollar de Albatera, Mollar de Orihuela, Valencianas and Bordes were evaluated. The results prove the appropriateness of the PCR–RFLP technique for identifying pomegranate cultivars. All evaluated cultivars were differentiated according to their genetic profiles. There is a low correlation between pomegranate morphological and genetic traits on this study.
