环境工程微生物学综合性实验教学体系的构建与实践

Construction and practice of comprehensive experimental teaching system of Environmental Engineering Microbiology

环境工程微生物学实验是环境工程专业一门重要的专业基础必修课。该课程对专业课的学习具有重要影响。为了保证该课程的教学质量,我们构建了一个新的实验教学体系。该体系包括两部分内容:一是絮凝细菌的分离、筛选、条件优化、应用效果及特征分析;二是污染控制工程中放线菌、霉菌、酵母菌、原生动物及微型后生动物种类与数量分布调查。两部分实验均具有研究性和综合性。第一部分内容分为5个模块。这5个模块具有系统性和连续性,且有一定的挑战性。通过这部分实验,学生可掌握有关细菌的基本实验技术及研究方法。第二部分内容所涉及的是丝状微生物和真核微生物。这部分实验可使学生掌握此类微生物的基本实验技术及其应用方法。该体系内容丰富,与专业结合紧密,大大激发了学生的学习热情。通过该体系,可使学生全面获得环境工程微生物基本实验技能,并有助于提高学生的综合能力,教学效果显著。

Environmental Engineering Microbiology experiment is an important professional foundation required course in environment engineering. This course has an important influence on the study of professional courses. In order to guarantee the teaching quality of the course, a new teaching innovation system is established. The system consists of two parts：（1） Separation, screening, optimization of conditions, application effect and characteristics analysis of flocculant;（2） Analysis on actinomycetes, mold, yeast and protozoan in pollution control engineering. The two part of the experiment is both research and comprehensive. The first part is divided into five modules. These five modules are systematic and continuous and given a certain challenge. Through this part of the experiment, students can grasp the basic experimental techniques and research methods of bacteria. The second part concerns the filamentous microorganisms and eukaryotic microbes. This part of the experiment can enable students to grasp the basic experimental technology and application methods of these microorganisms. The system is rich in content, closely combined with professional and has greatly stimulated the enthusiasm of students to learn. Through the system, the students can fully obtain the basic experimental skills of Environmental Engineering Microbiology and helps to improve students’ comprehensive ability. The teaching effect is very remarkable.
