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.

Apr 10, 2007· When cells are exposed to a medium with very little amounts of nutrient for a long time, the bacteria are altered physiologically (Daigger and Grady 1982). Sudden increase of carbon substrate concentrations causes the cell to change their physiology again. As PHA-synthesis requires less adaptation than growth, the culture starts producing polymer.

Typical pressures used to disrupt yeast are 8,000 to 10,000 psi and several passes through the press may be required for high efficiency of disruption. Generally, the higher the pressure, the fewer the passes. Pressure cells rated at 20,000 psi maximum come in capacities of 3.7 and 35m1 and there is also a 35m1 capacity cell rated at 40,000 psi.
