Influence of Cultural Conditions on Glutathione Peroxidase Synthesis in Candida albicans
The influence of cultural conditions that affect GPX production in Candida albicans grown in Lee's medium was investigated. Optimum temperature and pH for GPX activity were 25°C and 7.2, respectively. Substrate specificity for C. albicans. Glutathion peroxidase was in the order of cumene hydroperoxide>t-butyl hydroperoxide> hydrogen peroxide>benzoyl peroxide. Aeration as well as large head space volume enhanced the growth of C. albicans and GPX production. Arabinose and ammonium sulphate significantly increased the GPX synthesis. Among nitrogen sources, polypeptone enhanced both the growth and GPX synthesis. Various cellular activities are regulated by the level of GSH. Therefore, the level of GPX might be used as one of the criteria in developing new drugs against Candida albicans.
