First: Natural Polymers:
a– Types: Cellulose – Hemicellulose – Lignin – chitin Starch – Pectin – Protein (Keratin).
b- Chemical composition, degradation enzymes and deg-radation pathways.
Second: Synthetic Polymers:
a- Types and chemical composition:Polyethylene – Polyvinyl alcohol – Polyester – Starch/ Polyvinyl alcohol (Blend)- Starch/ Polyester (Blend).
b- Environmental problems:Accumulation because of their resistance to biodegra-dation so that they become a global problem.
c- Factors enhancing their biodegradability:
1. Abiotic oxidation by exposing them to heat or sun-light.
2. Production of biodegradable blends by mixing them with ferric, manganese or cobalt stearates.
3. Production of starch / polymer blend.
d- Measure of degree of biodegradability:
1. Use of scanning and transmission electron micro-scopes.
2. Determination of dry weight.
3. Use of Fourier Transforms – Infra Red Spectrosco-py (FT-IR).
4. Changes in the mechanical properties (Tensile strength).
e- Role of Fungi and their enzymes in biodegradation of natural and synthetic polymers:
Third: Practical Studies on Fungi involved in Bio-degradability:
1. Morphological and microscopial features of certain species of the following genera:
Aspergillus, Penicillium, Paecilomyces, Cladosporium, Fusarium, Chaetomium, Geotrichum, Aureobasidium, Thielavia, Candida, Pleurotus, etc.,
2. Detection of enzymes involved in biodegradation and quantitative estimation of their activities.
