Microbial Degradation

Microbial degradation refers to the breakdown of cannabis plant material and cannabinoids through microbial activity—primarily by bacteria and fungi in soil, storage conditions, or composting environments. This process is relevant to seed preservation, post-harvest handling, and understanding how cannabis genetics persist or degrade in natural ecosystems. Breeders and seed banks study microbial degradation to develop better storage protocols that protect genetic viability. The rate and extent of degradation depends on moisture, temperature, oxygen availability, and the microbial community present. While some degradation is inevitable in organic material, controlling conditions minimizes loss of cannabinoid potency and seed germination rates. Understanding this process informs best practices for long-term genetic conservation.

Seed bankers and breeders monitor microbial degradation risk to design storage environments—sealed, cool, low-humidity conditions that inhibit microbial growth. Knowledge of degradation pathways also helps breeders select for plant material stability and informs composting protocols when disposing of breeding waste.
