自养营养

It indicated that not only can Spirulina cells grow photoautotrophically and photomixtrotrophically, but also can grow heterotroph ically under some specific conditions. light intensity, light quality, temperature, species and concentration of metals, rare

认为螺旋藻细胞不但能进行光合自养和混合营养生长，而且在某些特定的环境条件下，还能进行异养生长；光照强度、光质、温度、金属元素、稀土元素、盐度、藻体细胞浓度、溶氧水平、维生素、激素和磁场等环境因素对螺旋藻细胞的光合性能和细胞产率都有显著影响。

The above results are useful for the cultivation of transgenic cyanobacteria in enclosed photobioreactors, and would promote the application of mixotrophic cultivation system in microalgae cultivation. Besides, they are also useful to understand the interrelation between photoautotrophy and heterotrophy in cyanobacteria.

本文的研究结果在实践上可为转基因蓝藻的光生物反应器培养奠定理论和实验基础，同时可促进混合营养培养系统在微藻培养中的应用，在理论上有助于提高人们对于蓝藻光自养和异养代谢的相互作用和蓝藻光合作用及其调控的认识。

It was shown that glucose utilization affected the primary carbon metabolic flux of cells. The oxidative branch of pentose phosphate pathway was apparently more active during mixotrophic growth than that during photoautotrophic growth.

结果表明，葡萄糖的利用影响了细胞初级碳代谢的流动状况，混合营养生长过程比光自养生长过程磷酸戊糖途径氧化性分支的反应程度明显加强。

The strain of Spirulina is very important in the culture, so we filtrate the best strain S_2 from three strains S_1、S_2、 S_3 via the experiments of phototrophic batch culture and mixotrophic batch culture, and detected the empoisoning of the used medium. In the end we found no fomite, so it is highly advantageous to culture.

螺旋藻培养过程中藻种的质量非常重要，为此本试验首先从三株藻株S_1、S_2、S_3中通过光合自养和混合营养分批培养筛选出优良藻株S_2，并且对培养液进行污染检查，未发现染菌，大大的减少了工作量。

The oxygen of output in phototrophic culture is much more than the input in the heterotrophic culture, the active high concentration oxygen bring out free radical O_2~- to a great extent, which is tremendously devastating.

螺旋藻混合营养培养过程中光合自养放氧量远大于异养耗氧量，高浓度的活性氧极易生成O_2~-自由基，具有极大的破坏性。

Producers are often referred to as being in the first trophic level and are called autotrophs by the heterotrophs.

生产者通常被称为第一营养级，被异养称为自养。

Holophytic The type of nutrition in which complex organic molecules are synthesized from inorganic molecules using light energy.

自养的：是利用光能将无机分子合成为复杂的有机分子的一种营养方式。

It was found that mixotrophic growth wasalways advantageous to photoautotrophic growth in photobioreactors.

结果表明，鱼腥藻7120在光生物反应器中的混合营养生长总是优于对应的光自养生长。

Photoautotrophic growth and mixotrophic growth in nitrogen-containing mediumwere better than those in nitrogen-free medium,respectively.

鱼腥藻7120在含氮培养基中的光自养生长和混合营养生长优于在无氮培养基中。

The output rate in mixotrophic fed-batch culture was 3.8 times as much as in photoau-totrophic batch culture and 3.1times as much as in mixotrophic culture.

产率是光合自养分批培养的3.8倍，混合营养分批培养的3.1倍。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
