Plants, including cannabis (
Cannabis sativa subsp.
sativa), host distinct beneficial microbial communities on and inside their tissues and organs, including seeds. They contribute to plant growth, facilitating mineral nutrient uptake, inducing defence resistance against pathogens, and modulating the production of plant secondary metabolites. Understanding the microbial partnerships with cannabis has the potential to affect the agricultural practices by improving plant fitness and the yield of cannabinoids. Little is known about this beneficial cannabis-microbe partnership, and the complex relationship between the endogenous microbes associated with various tissues of the plant, and the role that cannabis may play in supporting or enhancing them. This review will consider cannabis microbiota studies and the effects of endophytes on the elicitation of secondary metabolite production in cannabis plants. The review aims to shed light on the importance of the cannabis microbiome and how cannabinoid compound concentrations can be stimulated through symbiotic and/or mutualistic relationships with endophytes.

20 randomly selected samples submitted for testing at the
Steep Hill Facility in Berkeley, California all had detectable levels of microbial contamination, and many had significant pathogenic microorganism contamination (2). The variety of potentially harmful bacteria and fungi found was surprising and included:
- Klebsiella, Pseudomonads (several, including P. aeroginosa)
- Enterobacteria (including both pathogenic and non-pathogenic forms of E. coli)
- Acinetobacter (several, including baumannii)
- Aspergillus (in-cluding niger)
- Fusarium
- Mucor
- Penicillium
- Botryotini
- And many other bacteria and fungi
- Some of the samples studied harbored multiple potentially pathogenic microorganisms (e.g., Aspergillus, Fusarium, Penicillium, Enterobacter, Pseudomonas)

Biotransformation: NIH
The microbial biotransformation of Δ[9] -tetrahydrocannabinol was investigated using a collection of 206 alkane-degrading strains. Fifteen percent of these strains, mainly gram-positive strains from the genera Rhodococcus, Mycobacterium, Gordonia, ...

The most frequently found metabolites were compounds 3 and 4. Probably compound 4 was formed as a result of the action of an alkane monooxygenase, in combination with two aspecific dehydrogenases (possibly, but not necessarily, alkanol dehydrogenases).
