This paper reviews the occurrence and distribution of BaP in environment, as well as the ability and pathway for BaP degradation by microorganisms. In addition, approaches for improving microbial degradation of BaP are discussed.

本文综述了不同环境中BaP的来源与分布，BaP在环境中的行为，微生物对BaP的代谢途径，以及微生物降解BaP的相关限制因子，并结合作者在这方面研究的部分工作与目前国际研究的热点，提出值得进一步探究的有关问题。

Environment-friendly bast fiber film is buried in the ground floor of different soil pH value to study degradation and changes in the type and quantity of micro-organisms, to explore environment-friendly bast fiber film degradation relevance between micro-organisms and soil pH value. There are three types of soil, for example, weak acid soil, neutral soil, weak alkaline, in which film is buried. It is to determinate of weight loss and changes of quantity of micro-organisms around.

为了探明麻地膜降解性能与土壤pH和土壤微生物的相关性，利用生石灰调节土壤pH，将土壤pH调节为弱酸性、中性、弱碱性3个不同的水平，将麻地膜埋入3种不同的土壤中，定期测定其失重率及其周围土壤微生物种类和数量的变化。

As temperature increased from 40 to 70℃, ferric reduction capacity of microorganism biocoenosis from Jilin, Tianjin and Hunan paddy soil were restrained to a certain extent. Adding AQDS could increase ferric reduction rate of microorganisms biocoenosis from Jilin, Tianjin and Sichuan paddy soil significantly. In axenic culture treatment of 6 kinds of bacterial strain experiments from Sichuan and Jiangxi paddy soil, a bacterial strain was suitable to 50℃.

于40~70℃升温处理后，来源于吉林、天津和湖南水稻土微生物群落的铁还原能力受到一定程度抑制；添加AQDS可显著增加来源于吉林、天津和四川水稻土的3种微生物群落的铁还原反应速率；在6株铁还原菌的纯培养试验中发现了1株更适于在50℃下生长的菌株。

5 kinds of paddy soil treatments were studied, then each microorganism biocoenosis was extracted or bacterial strain was dissociated. Artificial synthesis ferric oxide was considered only electron acceptor, which inoculated soil leaching liquor or bacterial strain with reduction function in mineral salt culture system under anaerobic constant temperature condition. After different temperature treatments towards leaching liquor, temperature was controlled and AQDS added into culture system in order to discuss the effect of temperature and AQDS on ferric oxide microorganism reduction process.

采用5种水稻土为供试材料，分别提取微生物群落或分离铁还原菌株；以人工合成氧化铁作为惟－电子受体，在无机盐培养体系中接种土壤浸提液或具有铁还原功能的菌株，厌氧恒温培养；通过对接种液的不同温度处理(40， 50， 60， 70℃)、对培养温度的控制（30和50℃）以及向体系中添加AQDS，探讨温度及AQDS对氧化铁微生物还原过程的影响。

Traditionally, it is tedious and time-consuming because it follows the character of bioecology .

摘 要：传统的微生物分类和鉴定方法主要是以微生物的形态学和生理生化等特性为依据，繁琐且费时。

Thus, microbial carbonates should be classified within the limestones. Similar to reef rocks, microbial carbonates are frequently developed in strata from the Precambrian through to the Phanerozoic, in three forms: reef, biostrome and bioherm.

微生物碳酸盐岩，总体上构成生物作用类碳酸盐岩中的粘结岩类，以其明显的微生物作用特点而具有自己的分类体系；它不但作为生物礁岩石的主要类型，而且也常常以生物礁、生物层和生物丘三种形式发育在地层之中。

In as much as the two important fermentation in such foods are oxidative and alcoholic, the growth of organisms will be controlled by the acidity of the medium.

能量的来源——由于微生物的直接需要是能量来源，因而利用方便的可溶性碳水化合物影响着将要占支配地位的微生物的数目。

Compared with the control, intercropping Centaurea cyanus and Ocimum basilicum L increased the microbial quantity significantly in different developing periods and at each soil layer, as well as regulated the ratio of the soil fungi, bacteria and actinomyees in soil microbial community.

梨园间作香矢车菊和柠檬罗勒较对照显著提高各个发育时期和各土层中土壤微生物的数量，调节土壤微生物群落中真菌、细菌、放线菌的比例。

In addition, the membrane polarization time is gained from cell's simplified equivalent circuits and approved by system time constant of the state space equations of cell suspended system. Secondly, Laplace equations of the ideal model are built based on Faraday's Law, Gauss's Law, and charge conservation to analyze and calculate the amplitude and variation of transmembrane potential detailedly.

为了对微生物脉冲电场效应进行理论上的分析，首先，本文从细胞膜的结构、组成及功能入手，建立了微生物细胞的介电模型，求出了细胞膜的介质极化时间常数，并通过系统状态空间方程对其进行了验证。

In the United States, chronic alcoholism and hepatitis C are the most common ones.
