A comparative study of the growth and structural organization of Ganoderma lucidum and Ganoderma resinaceum mycelia for biocomposite development

Abstract

The building sector is a major contributor to greenhouse gas emissions owing to the widespread use of petroleum-derived materials and the high energy demand associated with heating and air conditioning. In this context, improving thermal insulation represents an important lever for reducing building-related environmental impacts. Mycelium-based composites are therefore increasingly investigated as sustainable alternatives to conventional insulation materials. As their performance strongly depends on fungal colonization and network architecture, understanding mycelial growth and structural organization is a necessary preliminary step for strain selection and biocomposite development. Aim of the study: The aim of this study is to characterize and compare the growth behavior and structural organization of Ganoderma lucidum and Ganoderma resinaceum mycelia under different temperature conditions, as a preliminary step toward strain selection for biocomposite development.
