Lichen and Its Microbiome as an Untapped Source of Anti‐Biofilm Compounds
Lichens and their associated fungi give rise to the evaluation of several extracts and compounds against biofilms. ABSTRACT Lichen substances have been first described in the 1870s, and around 10 000 compounds have been isolated and characterized. Most of them have been evaluated for their activity on planktonic microorganisms (bacteria and fungi ...

Conventional and innovative approaches to black fungi control for stone heritage preservation
Abstract Black Meristematic Fungi (BMF) are characterized by a thick melanized cell wall and an isodiametric cellular expansion. BMF represent one of the most damaging groups of microorganisms causing the deterioration of outdoor exposed stone monuments mainly due to the formation of dark spots and patches leading to the darkening of their surface ...

Herbicidal and Plant-growth Stimulating Effects of Phenolic Compounds Isolated from Lichens
The depsides atranorin (7) and diffractaic acid (1), the depsidones hypostictic (2) protocetraric (3), salazinic (4) acids, the xanthone secalonic acid (5), and usnic acid (6) were evaluated for their phytotoxic potentials against the target species ...

Lichen Polyphenolic Compounds for the Eradication of Candida albicans Biofilms
Lichens, due to their symbiotic nature (association between fungi and algae), constitute a chemical factory of original compounds. Polyphenolic compounds (depsides and depsidones) are the main constituents of lichens and are exclusively biosynthesized by

Biosynthesis of Depsides, Depsidones, and Diphenyl Ethers from Fungi and Lichens
Depsides are natural products derived from (poly)phenolic acid derivatives connected by ester bonds. Recent research has revealed crucial molecular mechanisms and distinctive enzymatic chemistry underlying the biosynthesis of depsides, as well as related natural products, such as depsidones and diphenyl ethers.

A Novel b-Orcinol Depsidone of Lichen Lobaria pulmonaria [PDF]
In continuation of our phytochemical survey of Lobaria pulmonaria has led to the identification of deoxystictic acid in this foliose lichen species for the first time. The isolated β-orcinol depsidone showed moderate anti-hydroxyl radical activity using fluorescence spectroscopy at in vitro conditions.
