Bioprocess engineering is a highly interdisciplinary field of study which is strongly benefited by practical courses where students can actively experience the interconnection between biology, engineering, and physical sciences. This work describes a lab course developed for 2nd year undergraduate students of bioprocess engineering and related disciplines, where students are challenged with a real-life bioprocess-engineering application, the production of recombinant protein in a fed-batch process. The lab course was designed to introduce students to the subject of operating and supervising an experiment in a bioreactor, along with the analysis of collected data and a final critical evaluation of the experiment. To provide visual feedback of the experimental outcome, the organism used during class was Escherichia coli which carried a plasmid to recombinantly produce enhanced green fluorescent protein (eGFP) upon induction. This can easily be visualized in both the bioreactor and samples by using ultraviolet light. The lab course is performed with bioreactors of the simplest design, and is therefore highly flexible, robust and easy to reproduce. As part of this work the implementation and framework, the results, the evaluation and assessment of student learning combined with opinion surveys are presented, which provides a basis for instructors intending to implement a similar lab course at their respective institution.
生物过程工程是一个高度跨学科的研究领域,实践课程对其有很大帮助,在这些课程中,学生可以积极体验生物学、工程学和物理科学之间的相互联系。本文描述了一门为生物过程工程及相关学科的本科二年级学生开发的实验课程,在该课程中,学生面临一个实际的生物过程工程应用挑战,即在补料分批培养过程中生产重组蛋白。该实验课程旨在向学生介绍在生物反应器中操作和监督实验的主题,以及对收集到的数据进行分析和对实验进行最终的批判性评估。为了提供实验结果的可视化反馈,课堂上使用的生物体是大肠杆菌,它携带一个质粒,在诱导后可重组产生增强型绿色荧光蛋白(eGFP)。通过使用紫外线,在生物反应器和样品中都可以很容易地看到这种蛋白。该实验课程使用的是最简单设计的生物反应器,因此具有高度的灵活性、稳定性且易于重复。作为这项工作的一部分,介绍了该课程的实施和框架、结果、对学生学习的评估以及结合意见调查的情况,这为打算在各自机构实施类似实验课程的教师提供了一个基础。
