To make comparison of adaptability of the plastid-less mutant and the wild type strain, we studied their growth characters under different culture conditions, found that the difference of their growth in a medium rich in organic substances are hardly detectable and that the loss of plastid exerts only a weak effect, if any, on the heterotrophic growth.

为比较完全失去质体结构的突变株和野生型的适应力，我们对二者在不同条件下的生长特性进行了研究，结果发现野生型与突变株的生长在有机质丰富的培养液中差别微弱，质体的丢失并不产生显著影响。

Flocculation+0.45μm filter is selected as the pretreatment of the method proposed here.(9) A set of standard methods for ASMs COD characterization is suggested in the thesis and it advantages are:①Respirometry is adopted to measure RBCOD and SBCOD;②SI is determined from raw wastewater and so there is no influence of inert products;③Heterotrophic biomass in wastewater is measured;④The key instrument used in the standard methods-hybrid respirometer, has high automatic level and friendly user interface which simplifies the respirometry. So the suggested standard methods are practical.(10) According to the suggested standard methods, the influent COD of a wastewater treatment plant in Chongqing, China, is characterized.

9提出一套表征城市污水COD组分的标准化方法建议，其特点在于：①以呼吸测量作为RBCOD和SBCOD的测量方法，与以往以物理化学方法为主的做法有着本质区别；②对原水直接进行分析测试来获得SI组分，不受溶解性惰性产物的干扰；③考虑了污水中活性异养微生物组分的单独测量；④所依赖的核心仪器-呼吸测量仪具有很高的自动化程度和简单友好的用户界面，使原本复杂的呼吸测量实验及其结果的分析统计简单化，所建议的标准化方法具有很好的实用性。
