新工科背景下“微生物生理学”虚拟仿真实验教学模式探索：以“微生物絮凝剂合成机制及应用”为例

微生物生理学是哈尔滨工业大学微生物学及环境科学与工程学科领域的硕士研究生精品核心课程，但由于传统微生物学实验教学耗时长、过程不确定及不可逆等因素，难以开展“微生物生理学”综合性研究生专业课程实验。将先进的虚拟仿真和互联网技术相结合构建“微生物生理学”虚拟仿真实验系统，可以有效突破课程实验教学的时空障碍，推进微生物学及环境科学与工程的研究生教育改革。本文以“微生物絮凝剂合成机理研究及应用”为例，从微观尺度到宏观尺度逐渐展开，实验内容涵盖微生物絮凝剂合成机理和微生物絮凝剂的应用，以培养学生综合利用所学知识探索微生物絮凝剂合成及应用的内在机理的能力，并鼓励学生独立思考，激发其科研热情。

Exploration of virtual simulation experiment teaching mode of Microbial Physiology under new engineering background: taking the mechanism research and application of microbial flocculant synthesis as an example

Microbial Physiology is a core course of microbiology and environmental science and engineering at Harbin Institute of Technology. However, the traditional experiment teaching approach, which is time-consuming, uncertain and irreversible, is difficult to offer fully professional experiments in the classes of Microbial Physiology. Building a virtual simulation experiment system for Microbial Physiology through the combination with advanced virtual simulation technology and internet technology can break the time and space limits in the experiment teaching and promote the reform of postgraduate education in microbiology and environmental science and engineering. We take the mechanism research and application of microbial flocculant synthesis as an example to explore the teaching from micro to macro scales, aiming to cultivate students'' ability of studying the underlying mechanism of microbial flocculation with the knowledge they have gained, encourage students to think independently, and stimulate their enthusiasm for scientific research.
