PDF Cell disruption methods Mohanlal Sukhadia University

Figure 1. Methods of microbial cell disruption (Geciova J., 2002) Different cells have different structures; hence they require different methods for disruption. Cell walls act as additional disruption deterrents, with yeast cells being particularly difficult to disrupt, as the cell wall limits the solvents access to the desired products.
