Chitin, also known as Shellfish Polymer, acts as a flocculant and chelating agent for oils, metals and organic materials in the pool water. Improved detection and identification of aquatic fungi and chitin in aquatic environments Christian Wurzbacher & Hans-Peter Grossart Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB), Dept. Chitin and microcrystalline cellulose were combined with different commercially Figure 3. Means for Classification: Saccharomyces cerevisiae is in the fungi kingdom. Chitinases are produced by higher plants to defend themselves against pathogenic attacks by degrading chitin in the cell walls of fungi and bacteria.
