The role of lichenized algae in the production of Cladonia verticillaris depsidones, revealed by using alginate-immobilized cells

The mycobiont of the lichen Cladonia verticillaris produces two depsidones, protocetraric and fumarprotocetraric acids, in the nature. This last compound is produced from the former depsidone. To study the role of the algal partner in the production of these depsidones in the lichen thallus, fungal...
