The activity of hydrolases of entomopathogenic nematodes

Similar patterns of hydrolases were observed in three species representing two genera of entomopathogenic nematodes: Steinernema affinis, S. feltiae, and Heterorhabditis zealandica. The same enzymes were present in the studied nematodes but they differed in the level of activity of individual sub-classes of enzymes. A higher activity of esterases and proteolytic enzymes could be observed for H. zealandica than for S. affinis and S. feltiae. On the other hand, the activity of glycosidases in steinernematids was generally much higher than in H. Zealandica.
