光合细菌生长及氮磷同化率影响因素的研究

摘要: 从湖水表层水样中筛选出纯净的光合细菌菌种。通过对光合细菌中的沼泽红假单胞菌在不同成分培养基学生长情况研究，结果表明该菌生长的最适pH值为6.5—7.5，最适温度在25℃—35℃范围之间，最适合纯种菌液接种量为10%，盐度低于2 g•L-1，OD值逐渐下降；氮磷同化率与之对应。通过不同微量元素金属离子对光合细菌生长影响及氮磷同化率的研究，发现Mn2+、Zn2+对光合细菌生长有无明显促进作用，Cu2+对PSB生长具有一定的正效果，0.1mg•L-1达到最高值；Mn2+ 、Cu2+对其氮磷同化能力起增强作用，分别在0.15mg•L-1、0.2mg•L-1达到最高值。

从湖水表层水样中筛选出纯净的光合细菌菌种，对其生长及氮磷同化率进行了研究。结果表明，细菌沼泽红假单胞菌生长最适接种量为10%；最适盐度为2g/L；最适pH值为6.5—7.5；最适温度为25℃—30℃；氮磷同化率与光合细菌生长量呈正相关。通过把三种微量元素与菌种进行正交实验，分析统计结果表明：Mn2+ 、Zn2+、Cu2+都对光合细菌生长有一定的促进作用，相对影响程度：Zn2+＞Mn2+＞Cu2+。当液体培养基中Mn2+浓度为0.15mg•L-1、Zn2+浓度为0.10mg•L-1、Cu2+浓度为0.20mg•L-1时菌种生长得最好，相应的氮磷同化能力也能达到最佳。

修正那几个地方没有改呀，

追答

你所指出的笔误，如 培养基学——培养基；有无——无；我在翻译都时候就已经是这么理解的。
至于这个，OD值逐渐下降——盐度低于2 g•L-1后OD值逐渐下降，我已经加了after - OD value was dropping gradually after the salinity was below 2 g•L-1,...................

我已帮您仔细检查过了，只有盐度 salinity 缺了一个s。放心吧！

A research was conducted on the growth and the assimilation rate of nitrogen and phosphorus of pure strains of photosynthetic bacteria (PSB) that was isolated from lake surface water samples. The result shows that the most suitable liquid inoculation amount for rhodopseudomonas palustris bacteria is 10%; most suitable salinity is 2g/L；most suitable pH value for the growth of the bacteria is 6.5—7.5; most suitable temperature is between the range of 25℃—35℃, and there is a positive correlation between the assimilation rate of nitrogen and phosphorus and the growth rate of the photosynthetic bacteria. After conducting Orthogonal experiments on the strains with three different trace elements, the analyzed statistical results show that Mn2+ , Zn2+ and Cu2+ have certain promoting effects on the growth of PSB; the relative degree of the effects: Zn2+＞Mn2+＞Cu2+. The optimum growth condition for the bacteria strains is when the concentration of Mn2+ , Zn2+ and Cu2+ in the liquid culture medium is 0.15mg•L-1, 0.10mg•L-1 and 0.20mg•L-1 respectively; the corresponding assimilation rate of nitrogen and phosphorus can also reach optimum performance.

Research of the Elements Affecting the Growth of Photosynthetic Bacteria and NPD Assimilation Ratio

Abstract: Select out the pure photosynthetic bacteria from the water sample got from the surface of the lake. After the research of the growth status of the rhodopseudom onas palustris in photosynthetic bacteria in different culture medium, the result shows that the most proper PH for this bacterium to growth is 6.5-7.5, and the proper temperature is 25℃—35℃, when the most proper inoculum concentration is 10%, with the salinity lower than 2 g•L-1, and OD descends gradually; NPD assimilation ratio is consistent with that. Though the research of effect by different metal ions to the growth photosynthetic bacteria and NPD assimilation ratio, we found that Mn2+, Zn2+has little effect on the growth of photosynthetic bacteria, while Cu2+ take some positive function on the growth, and when 0.1mg•L-1, it arrives the climate; Mn2+ 、Cu2+ enforce the NPD assimilation, and it reaches the climate at 0.15mg•L-1and 0.2mg•L-1 separately.
