Název v původním jazyce

Characterization of chitinases of polycentric anaerobic rumen fungi

Popis výsledku v původním jazyce

Chitinolytic system of anaerobic polycentric rumen fungi of genera Orpinomyces and Anaeromyces was studied in three crude enzyme fractions- extracellular, cytosolic and cell wall fraction. Endochitinase was found as a dominant enzyme with highest activity in cytosolic fraction. Endochitinases of both genera were stable from pH 4.5 to 7 with optimal pH 6.5. Orpinomyces endochitinase was stable up to 50 0C with optimal temperature 50 0C. Anaeromyces endochitinase was stable up to 40 0C with optimal temperature also 40 0C. The most suitable substrate for both endochitinases was fungal cell wall chitin. Enzyme activities were inhibited by Hg2+ ions and activated by Mg2+ ions. Both endochitinases were inhibited by 10 mM SDS and activated by iodacetamide.
