The Klason lignin level of anti-4CL-transformed tobacco was much lower than that of the control. The cellulose content increased in transgenic tobacco with UGPA constructs.We also obtain transgenic tobacco transformed with Acetobacter xylinum UGPase gene.

研究了木醋酸菌来源的UGPase基因与植物来源的UGPA基因在转基因烟草中的表达，测定了两种转基因烟草的尿苷二磷酸葡萄糖焦磷酸化酶的活性、木质素含量和纤维素含量。

Compared the lignin and cellulose level of these two kinds of transgenic tobacco, we found that the cellulose content increased and the lignin content deduced in transgenic tobacco transformed with Amorpha fruticosa UGPA constructs, both the cellulose content and the lignin content increased in transgenic tobacco transformed with Acetobacter xylinum UGPA constructs.

结果表明，两种转基因烟草的尿苷二磷酸葡萄糖焦磷酸化酶的活性均有明显提高；转紫穗槐UGPA基因的烟草纤维素含量有所提高，木质素含量略有降低，纤维素与木质素含量之大连理工大学博士学位论文比提高；而转木醋酸菌来源的UGPase基因的烟草木质素含量和纤维素含量均显著提高。

Separating acetobacter acetic strains adopted the changing colour circle method with bromocresol purple indicator.

采用溴甲酚紫作为指示剂通过变色圈法，从其中分离醋酸菌。

The results showed that the microorganism in FAP were mainly yeast, acetbater and lactobacilli.

Today, the acetic acid bacteria are classified as the consensus result of a polyphasic analysis, combining phenotypic, chemotaxonomic and genotypic data.

如今， 大多采用结合表型、化学分类法和基因型数据的多相分类法对醋酸菌进行分类。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
