Abstract

Abstract In the present study, the effect of exopolysaccharides (EPSs) extracted from Pseudomonas tolaasii on the growth of Pleurotus ostreatus mycelia was determined. P. ostreatus mycelia was cultivated with different concentrations of P. tolaasii EPSs, and their mycelial growth rate, protein content, and enzyme activity were measured and compared. The results showed that EPSs inhibited the growth of P. ostreatus. The proline and vitamin C contents of P. ostreatus increased at an EPS concentration of 40%. The cellulase, α-amylase, protein, and glucose utilisation rates of P. ostreatus gradually decreased with the increase in EPS concentration. Altogether, P. tolaasii EPSs had a significant inhibitory effect on mycelial growth. Therefore, we concluded that in addition to tolaasin, EPSs may also be the virulence factors responsible for the pathogenesis of P. tolaasii.
