Summary

This article discusses methods for measuring the mechanical properties of single microbial cells. A key technique is compression testing using micromanipulation, which applies controlled forces to individual cells. The method is especially useful for understanding how cells respond to mechanical stress in bioprocessing. Mathematical models help interpret the results, particularly in yeast cells. The study highlights that cell wall structure and composition affect mechanical behavior. However, predicting when cells will break during processing remains difficult. Future research may combine this method with other single-cell approaches to better understand cell mechanics and link them to gene expression.
