As an alternative to conventional sterilization methods the plasma ions created from high voltage produce radicals which have a direct impact on microorganisms in water Cell membrane fluidity is an important factor in survival as the fluidity allows for essential cell functions in which pH and fatty acids play a major role This study investigated the effect of plasma application upon pH and fatty acid profiles of Escherichia coli and Staphylococcus aureus Results showed that plasma sterilization is not predominantly a result of changes to pH levels or fatty acid contents in the bacterial cell membrane Crown Copyright (C) 2010 Published by Elsevier B V All rights reserved
