Trametes versicolor, a white rot fungus, can also produce high amount of EPS. EPS production varies depending on fermentation method, production conditions, nutrient sources (especially glucose concentration) in the medium, and also the strain used. Therefore, in this study, EPS production ability of T. versicolor strain collected from Hatay/Turkey was firstly investigated during the repeated-batch fermentation (RBF) process. T. versicolor was incubated under RBF condition. After investigating the EPS production in different media during repeated-batch process, the effect of medium retention time on EPS production was determined. Then; the effects of agitation, temperature, pH, amount of pellets used and amount of glucose on EPS production were determined. The results of the study showed that both production conditions and glucose concentration affect the EPS production of this strain during the RBF process. © 2025, Adiyaman University.
