Digestive function of lysozyme in synanthropic acaridid mites enables utilization of bacteria as a food source
Original language description
The activity of lysozyme, the enzyme that hydrolyzes peptidoglycan in G+ bacterial cell walls, was detected in whole mite extracts (WME) and in spent growth medium extracts (SGME) of 14 species of synanthropic mites (Acari: Acaridida). The adaptation oflysozyme for digestive activity and bacteriophagy was based on: (i) high lysozyme activity in SGME, and (ii) the correlation of maximum lysozyme activity at acidic pH values, corresponding to pH in the ventriculus and caeca. We show that the digestion offluorescein-labeled Micrococcus lysodeikticus cells began in ventriculus and continued during the passage of a food bolus through the gut. The fluorescein was absorbed by midgut cells and penetrated to parenchymal tissues. Eight species showed a higherrate of population growth on a M. lysodeikticus diet than on a control diet. The lysozyme activity in SGME was positively correlated to the standardized rate (rs) of population growth, although no correlation was found between rs and lyso
