The third part is development experiments of antisepsis algicide coatings.

第三部分是抗菌藻涂料的研制试验。

Porphyridium cruentum were treated with some antibiotics which were used as genetic selected marks in genetic engineering. The results showed that the algae cells could resist high concentration of Penicillin,Streptomycin,Gentamicin and Kanamycin, without any influence at the dose below 100 u/mL of which can kill bacterium adhere to the algae cells . These antibiotics can be used to repress bacterium in purifying algae strain.Porphyridium cruentum is high sensitive to Erythromycin,Terramycin and Ofloxacin....

研究了基因工程中常用抗生素标记对紫球藻的生物学效应，结果表明紫球藻对青霉素、链霉素、庆大霉素以及卡那霉素较不敏感，剂量在100u/mL以下对其生长无显著影响，但能抑制或杀灭伴生的杂菌，因此这些抗生素可用于藻种纯化过程中抑菌；紫球藻对红霉素、氧氟沙星和土霉素非常敏感，低质量浓度就能杀死藻细胞，可用作基因工程或遗传育种的抗药性选择标记；对四环素和氯霉素较为敏感，明显抑制细胞生长，并呈浓度梯度效应。

It indicates that axenic microalgae may instead of nonaxenic microalgae for research on the physiological and biochemical characteristics of microalgae and the relationship between microalgae and other biology.

这说明可以直接利用无菌化微藻代替自然带菌藻进行微藻的生理特征以及微藻与其它生物之间关系的研究。

In this thesis, the biological characteristic of Dunaliella salina, which included the axenic purification, physiology characteristics and genetics characteristics, was studied systematically.

本文系统研究了杜氏盐藻的生物学特性，主要内容包括杜氏盐藻无菌纯化、杜氏盐藻生理学特性、杜氏盐藻遗传学特性等三部分。

Employing capillary-pipette washing method,the unialgal strain and axenic strain of Microcystis aeruginosa from Songhua Lake were isolated and purified,and effects of temperature,illuminance,nitrogen,phosphorus,and iron on their growth were investigated.

用毛细滴管洗净法从松花湖分离纯化出铜绿微囊藻的单藻株和无菌株，研究了温度、照度、N、P、Fe各种因素对单藻株和无菌株生长的影响。

Halophytophthora species are common zoosporic oomycetes in subtropical and tropical mangrove forest.

Halophytophthora属是红树林中常见的藻菌，多分离自红树林的落叶中。

The inhibitory effect of different density of Chaetoceros muelleri on the vibrios was studied in this paper.

研究了不同接种密度的牟氏角毛藻培育系统对2种弧菌的抑制效果及其相关性。

As a wide variation exists among this species, differentiating the harmful and beneficial strains would help in finding ways of controlling the infections by eliminating harmful shrimp pathogenic vibrios.

由于溶藻弧菌种内不同菌株存在较大的差异，区分有害菌株和有益菌株将有助于消除对对虾有害的治病性弧菌而寻找一种控制由溶藻弧菌引起的疾病的方法。

The second part is development experiments of an efficient antiepsis algicide.

第二部分是高效抗菌灭藻剂的研制试验。

This part consists of two stages. In the first stage, orthogonal tests are carried out between developed efficient composite antimicrobals FB-1, FB-2 and selected coatings. Experiments indicate the optimum recipe TUB is built by FB-2 and coating. In the second stage, the effect of built antisepsis algicide coatings is tested. Furthermore, static test indicates the effect of TUB is significant. So, it posses wide spread application value.

本部分试验共分为两个阶段，第一阶段将研制出的高效复合抗菌灭藻剂FB—1、FB—2与所选涂料进行配比试验，结果表明FB—2与涂料复配出了最优的抗菌藻涂料配方TUB；第二阶段是对复配出的抗菌藻涂料进行效果验证，静态试验表明TUB效果显著，具有极广的应用价值。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
