  5. 5. Bacterial Degradation and Use of Chitin in Aquatic Habitats

    Författare :Sara Beier; Stefan Bertilsson; Ian Head; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Chitin; organic matter degradation; microbial ecology; functional guild; Biology; Biologi;

    Sammanfattning : Chitin belongs to the most abundant biopolymers on earth where it has an important role as a structural element in crustaceans, insects, fungi and some phytoplankton. Missing evidence for long-term accumulation of chitin in nature implies fast turnover and as chitin is composed of aminosugar subunits it holds central roles in both carbon and nitrogen cycles.
