自养生物

Biofilm is one of the key factors of the one-step completely autotrophic nitrogen removal process under high DO.

生物膜是高溶解氧条件下实现单级自养脱氮的一个关键因素。

However,there is little study on the microorganisms vital for biological deodorization in China.

目前国内生物脱臭研究通常直接采用活性污泥挂膜，并认为生物脱臭过程主要是自养硫杆菌的作用，但这种方式存在着一个主要问题就是挂膜后有一个相当长驯化期。

Little light penetrates this zone and thus the inhabitants are all heterotroph ic, depending on the littoral and sublittoral organisms for basic food materials.

透过此区域的光很少，因此栖息生物都不是自养的，主要以浅海的和远浅海的生物作为基本食物来源。

PCC6803. In the enclosed photobioreactor, after 58. 5h mixotrophic cultivation, 2. 50g/L cell density, 1. 0g/L. d productivity, 15. 3μg/ml chlorophyll concentration and 25. 3%energy efficiency were achieved, which were respectively 8. 9 times, 11times, 2. 3 times and 4. 9 times as much as those in photoautotrophic culture.

在封闭式光生物反应器中，混合营养培养58.5小时，集胞藻6803藻细胞密度达到2.50g/L，是同期光自养的9倍，藻细胞产率为1.0g／L.d，是光自养培养的11倍，叶绿素浓度为15.3μg／ml，是光自养的2.3倍，能量得率为25.3％，是光自养培养过程的5倍。

The characters and performance of the biofilm were studied. When the concentration of nitrite is 206.82 mg/L, the velocity of nitrification is 260 mg/L·d. The best performed bacteria, N-20, were identified as Nitrobacter sp.

实验得到了稳定的自养硝化生物膜；当NO-2浓度为206.82mg/L时，生物膜的稳定硝化速率可达260mg/L·d；经鉴定，硝化速率最高的N20菌株属硝化杆菌属(Nitrobactersp。)。

The activities of nitrosification and anaerobic ammonium oxidation of both activated sludge and biofilm also were studied. Results showed that the nitrosification rate of activated sludge was 2.89 times than biofilm. AOB was the dominate bacteria in activated sludge.

单级自养脱氮系统中的活性污泥及生物膜样品均具有亚硝化活性，其中活性污泥最大比氨氧化速率为0.234mgN/mgVSS·d，生物膜为0.081mgN/mgVSS·d，活性污泥亚硝化活性是生物膜的2.89倍左右。

Autotrophs, the main producers in most terrestrial ecosystems, use energy from the sun or from the oxidation of inorganic substrates to produce organic molecules from inorganic ones.

自养生物——大多数陆地生态系统的主要生产者，利用太阳能或无机物质氧化作用的能量，使无机分子成为有机分子。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
