Chitin content and chitin synthase activity as indicators of the growth of three different anaerobic rumen fungi
1991
Gay, L.
Growth of three different anaerobic rumen fungi Neocallimastix frontalis, Piromonas communis and Sphaeromonas communis was assessed in vitro at regular intervals by measurements of protein and chitin content and of chitin synthase activity of the cell free extracts. Similar trends and a comparable amount of protein and chitin were observed in the three species. However, chitin synthase activity was higher in S. communis and contrary to the activity of the other two strains did not decrease after maximum enzyme activity was reached. There were positive correlations between chitin content, protein content and chitin synthase activity during the active growth phase of the fungi indicating that they could be confidently used to determine in vitro growth phase and biomass concentration.
