Application:	ACES has been used: • as a component of buffered charcoal yeast extract (BYCE) agar for plating bacteria culture and Buffered Yeast Extract (BYE) liquid medium to culture bacteria • to study the impact of the pH shift on the thermal inactivation of bacterial (Bacillus subtills) spores • as a buffer system to study the depolymerization of starch by α-amylase during exposure to hydrostatic pressure. It is also suitable for use: as buffers for both agarose and polyacrylamide gel electrophoresis; in the isoelectric focusing of proteins; in the analysis of bacterial autolysins in a discontinuous sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) system.
