Antimicrobial Compounds

Antimicrobial compounds in cannabis refer to volatile organic compounds and secondary metabolites that exhibit inhibitory properties against bacterial, fungal, or microbial growth. These include terpenes like limonene, pinene, and caryophyllene, along with phenolic compounds and cannabinoids that have been documented in laboratory settings to interact with microbial cell structures. Breeders and researchers studying cannabis genetics have observed variation in antimicrobial compound profiles across cultivars, influenced by strain lineage, environmental stress, and harvest timing. While antimicrobial activity has been measured in vitro, cannabis breeding focused on these traits remains largely experimental. Understanding these compounds is relevant to preservation, post-harvest handling, and fundamental plant biology research.

Breeders working in preservation genetics and seed-bank curation monitor antimicrobial compound profiles as part of long-term viability protocols. Strains with robust terpene and phenolic expression are often preferred in seed banking and storage programs to support natural resistance during dormancy.
