Costa Rican fungi as potential biomaterials

Main Article Content
Abstract
Fungal biomaterials are gaining relevance due to their intrinsic ability of self-repair, higher
sensitivity to external conditions and faster growth respective to synthetic materials. This project
consists of evaluating and characterizing the physical properties of fungal strains isolated
from a Pacific Coast Mangrove in Costa Rica. We identified environmental strains by recording
their morphological features and complemented this by ITS-based DNA barcoding, and
subsequently, classified three strains based on morphological features and seven strains by
molecular analyses. Ongoing work is being done to measure electrical responses of these fungi
upon light stimulation; in addition, a protocol for studying their piezoelectric properties is being
developed to identify potential candidates to be used in the field of electronics. To the extent of
our knowledge, our project is the first one to report piezoelectric properties from microscopic
fungi in Costa Rica as means to determine its potential as biomaterials.
