  2. Lignin peroxidase - Wikipedia

    en.wikipedia.org/wiki/Lignin_peroxidase

    Lignin is found to be degraded by enzyme lignin peroxidases produced by some fungi like Phanerochaete chrysosporium. The mechanism by which lignin peroxidase (LiP) interacts with the lignin polymer involves veratrole alcohol , which is a secondary metabolite of white rot fungi that acts as a cofactor for the enzyme.

  3. Lignin-modifying enzyme - Wikipedia

    en.wikipedia.org/wiki/Lignin-modifying_enzyme

    Historically, only a small fraction of plant biomass use could actually be extracted from pulp sources leaving the majority of the plants as waste products. Due to Lignin, the plant waste is relatively inert towards degradation and causes the large accumulation of waste products. LMEs can effectively break it down into other aromatic compounds ...

  4. Fungal extracellular enzyme activity - Wikipedia

    en.wikipedia.org/wiki/Fungal_extracellular...

    Production of lignin-peroxidase and manganese-peroxidase is the hallmark of basidiomycetes and is often used to assess basidiomycete activity, especially in biotechnology applications. [38] Most white-rot species also produce laccase, a copper-containing enzyme that degrades polymeric lignin and humic substances.

  5. Wood-decay fungus - Wikipedia

    en.wikipedia.org/wiki/Wood-decay_fungus

    Lignin is a biopolymer which combines with cellulose to form the lignocellulose complex, an important complex that confers strength and durability to plant cell walls. Lignin is a macromolecule formed from the combination of many phenolic aromatic groups via oxidative coupling. Because of its high stability, lignin is incapable of being broken ...

  6. Guaiacol - Wikipedia

    en.wikipedia.org/wiki/Guaiacol

    It is produced by a variety of plants. [4] It is also found in essential oils from celery seeds, tobacco leaves, orange leaves, and lemon peels. [5] The pure substance is colorless, but samples become yellow upon exposure to air and light. The compound is present in wood smoke, resulting from the pyrolysis of lignin.

  7. Lignin - Wikipedia

    en.wikipedia.org/wiki/Lignin

    In cooking, lignin in the form of hardwood is an important source of these two compounds, which impart the characteristic aroma and taste to smoked foods such as barbecue. The main flavor compounds of smoked ham are guaiacol , and its 4-, 5-, and 6-methyl derivatives as well as 2,6-dimethylphenol.

  8. Laccase - Wikipedia

    en.wikipedia.org/wiki/Laccase

    Laccases (EC 1.10.3.2) are multicopper oxidases found in plants, fungi, and bacteria. Laccases oxidize a variety of phenolic substrates, performing one-electron oxidations, leading to crosslinking. For example, laccases play a role in the formation of lignin by promoting the oxidative coupling of monolignols, a family of naturally occurring ...

  9. Hypersensitive response - Wikipedia

    en.wikipedia.org/wiki/Hypersensitive_response

    Hypersensitive response (HR) is a mechanism used by plants to prevent the spread of infection by microbial pathogens.HR is characterized by the rapid death of cells in the local region surrounding an infection and it serves to restrict the growth and spread of pathogens to other parts of the plant.
