SPECIFIC FUNCTIONS OF LICHEN ACIDS (SECONDARY METABOLITES)

Lichens produce two types of metabolites: primary metabolites (e.g. carbohydrates and amino acids) and secondary metabolites (e.g. alkaloids and lichen acids). Primary metabolites (which are intracellularly secreted) are critical to the survival of the lichens while secondary metabolites are rarely involved in the metabolism or growth of the lichenized fungi. Secondary metabolites of lichens are […]

LICHENS AND THEIR BIOLOGICAL SIGNIFICANCE

Lichen is simply a symbiotic association of slow-growing microorganisms that is composed mainly of a fungus and cyanobacteria or green algae. They are a composition of twin or double organisms, and are very rich in chemical compounds as expressed by the varying colours that they produce on the surfaces where they form. Lichens grow on
