| Popis: | Activity of reactive oxygen species (ROS) was investigated in liquid cultures of Penicillium chrysogenum P2 supplemented with carbohydrates. Oligosaccharides lowered the ROS activity in all samples. The greatest effect occurred when oligosaccharides were added to samples 48 h after inoculation. The ROS decrease in the presence of oligoguluronate, oligomannuronate and mannan oligosaccharides was 18%, 36% and 54%, respectively (ROS levels varied notably with culture age and type of elicitor). The polysaccharides from which the oligosaccharides were derived showed little (5-10%) overall decrease of ROS. |
