查询词典 hydrogenase

Using the length of cells' growth cycle,the density of cells and the activity of induced hydrogenase as criteria,the optimal formulation of culture medium was obtained as seTA(se -Tris Acet) which contains acetic acid as C source,higher concentration of N and stronger pH buffer system based on the se formulation.

结果发现，培养基的pH和氮素的含量是影响莱茵衣藻生长的重要因素；而培养基中醋酸根的含量则有助于提高厌氧产氢过程中衣藻的氢酶活性，从而提高其产氢量。

A 2 L tubular photobioreactor was designed, and hydrogen production by Rhodospirillum rubrum uptake hydrogenase deficient mutant in this PBR under artificial illumination condition (including continuous illumination and light/dark cycle condition) and natural day/night cycle was investigated, respectively.

本研究设计了一种2 L分体式管式光合反应器，并研究了深红红螺菌吸氢酶缺失突变株在该反应器中分别利用人工光源和自然光的产氢规律。

Six operational taxonomical units were obtained on the 16S rRNA gene but only one on the Fe-hydrogenase gene of Clostridium.

结果发现产氢菌群中至少有6种，而Fe-氢酶基因只含有一种。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
