Lignin degradation
Lignin are polymeric, non-carbohydrates containing parahydroxy phenyl propanes & are derived from shikimic acid. The examples of microbes involved in lignin degradation are:-
Â
Â
Fungi                                                             Bacteria
- Agaricus                       1) Arthrobacter
- Armillaria                       2) Flavobacterium
- Clavaria                        3) Micrococcus
- Cortinellus                      4) Pseudomonas
- Ganoderma                     5) Xanthomonas
- Mycena
- Pleurotus
- Polyporous
- Lycoperdon

After ring opening the Protocatechuic acid may produce acetic acid, succinic acid or pyruvic acids which ultimately produce CH4, CO2& H2O etc. after mineralization.
Enzymes involved:
- Lignase
- Phenol oxidase
- Lactose
- Peroxidase enzyme
