The physiological and biochemical mechanisms of Cinnamomum camphora xylem extracts inhibit wood-decay fungi

Abstract

The present study investigated the physiological and biochemical mechanism of extracts derived from Cinnamomum camphora (L.) Presl. The methanol and chloroform extracts of C. camphora xylem exhibited inhibitory activity against oxygen consumption in Coriolus versicolor and Gloeophyllum trabeum. The inhibitory effect of cellulose secreted by G. trabeum was concentration-dependent. The application of the ethyl acetate extracts of C. camphora xylem on the G. trabeum hyphae resulted in an improvement in electric conductivity, which followed a concentration-dependent fashion. Protein permeability increased with higher concentrations of the ethyl acetate extracts of C. camphora xylem. This research provided theoretical basis for understanding of the physiological and biochemical mechanisms of C. camphora extracts inhibit wood-decay fungi and the development of natural extracts as wood preservatives.

A Review on Natural Extractives as Protective Agent against Decay on Wood and Bamboo Products

“…Regarding ecotoxicity, coffee silver skin extract content is much lower than that of commercial wood preservatives, which had almost no mass loss. Chlorogenic acid and caffeine have been found to suppress fungi (Zhang et al, 2020 andXu et al, 2013); thus, this information shall not be disregarded as their derivatives might be useful as wood preservation against wood deteriorating fungi. discovered that chlorogenic acids could suppress the growth of mycelial and germination of spores in phytopathogenic fungi at 15 μg/μL.…”

The Impact of Fungicides, Plasma, UV-Additives and Weathering on the Adhesion Strength of Acrylic and Alkyd Coatings to the Norway Spruce Wood

“…Individual wood species have specific surface characteristics-wettability, free surface energy, porosity, roughness, pH-value, resistance to bacteria, molds, decaying fungi, etc. [24][25][26][27][28][29]. All surface characteristics of wood are directly connected with its geometrical, morphological, anatomical, and molecular structure [30].…”
