经对该富集培养物的分离培养，已分离出4株厌氧细菌，其中一株为甲烷八叠球菌，两株为弧菌，一株为杆菌。

The cultural condition of PGPR strains Temperature,pH,light,cultural method,acid or alkali producing,and salt tolerance of 9 PGPR strains isolated from Gramineous Forage were tested,the results showed that all the PGPR strains could grow in the temperature range from 5℃～45℃,and optimum temperature for 178,O-6,Dry6 strains was 35℃,for X5,173,Y5,C-6 strains was 30℃,for N4 strain was 25℃～35℃,for 86 strain was 25℃;most of PGPR strains prefered to neutral or alkaline condition,strains 178,O-6,N4 and X5 were preferable to alkali condition especially;light was beneficial to PGPR's growth;all of them produce alkali;most of PGPR strains were not sensitive to NaCl concentration;all the strains were aerobiotic bacteria.

结果表明：各供试菌株对温度的适应范围较广，在5℃～45℃范围内均能生长，178、O-6、Dry6 菌株的适宜生长温度为35℃，X5、173、Y5、C-6 菌株的适宜生长温度为30℃，N4 菌株的适宜生长温度为25℃～35℃，86 菌株的适宜生长温度为25℃；大部分菌株在中性或偏碱性的条件下生长好，特别是Dry6、N4 和X5 菌株对碱性环境适应性强，在pH 值8.0 时生长最好；光照有利于菌株的生长；绝大部分菌株在3%NaCl浓度下生长良好，在5%～7% NaCl 浓度下除173 和86 菌株外，其它菌株都能生长，即对盐份的耐受性较好，且9 个菌株均为产碱菌；除173 菌株是兼性厌氧细菌外，其它都是好氧性细菌。

For instance, motile aerobic bacteria are positively aerotactic, whereas motile obigate anaerobic bacteria are negatively aerotactic.

例如能动的需氧细菌表现出正的趋氧性，然而能动的厌氧细菌则表现出负的趋氧性。

Ammonia and nitrate, ferrous ion, sulfide, various gases and organic acids are sequentially formed, corresponding to the activities of aerobic and facultatively anaerobic bacteria, sulfate-reducing bacteria, and methane-producing bacteria with the development of reduction reactions.

在还原过程中，随着好氧细菌、兼性厌氧细菌、硫酸还原菌和甲烷菌的活动，相继形成氨、硝酸根离子、亚铁离子、硫化物、气体物质及有机酸。

The purpose of this study is to screen microorganisms with growth inhibition against plant fungal pathogens. The plate-dilution method was used to isolate the bacteria from salt marshes at Dafeng, Jiangsu. The antifungal activity of the bacterial broth filtrates against 5 phytopathogens was determined using mycelial disk method. The antifungal compositions of four active bacteria were analyzed primarily with chromatography techniques. Two hundred and thirty-five aerobic (92) and anaerobic (143) bacterial strains have been isolated from the coast salt marsh and sixty-five strains, of which 39 are aerobic and 26 are anaerobic showed greater than 30% of inhibition rate against the growth of at least one of the phytopathogenic fungi on petri dish.

为了开发对植物病原真菌生长有抑制作用的药源微生物，本实验采用平板稀释法从江苏大丰盐沼湿地土壤中分离微生物，并通过菌丝块法检测这些微生物代谢产物对5种植物病原真菌生长的抑制活性，进而利用柱层析分析其活性成分；结果共分离得到235株细菌，其中好氧细菌92株，厌氧细菌143株；体外活性测试结果显示有65株至少对1种测试植物病原真菌的抑制率在30%以上，其中好氧菌39株，厌氧菌26株。

The release of the carbon in these compounds for recycling depends almost entirely on the action of both aerobic and anaerobic bacteria and certain types of fungi.

这种化合物通过碳的释放来实现循环，主要依靠喜氧和厌氧细菌以及一些菌类的活动。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。
