Tribromoanisole is usually produced when naturally occurring airborne fungi and/or bacteria (usually Aspergillus sp., Penicillium sp., Actinomycetes, Botrytis cinerea, Rhizobium sp., or Streptomyces) are presented with brominated phenolic compounds, which they then convert into bromoanisole derivatives.
TCA is usually produced when naturally occurring airborne fungi and bacteria (usually Aspergillus sp., Penicillium sp., Actinomycetes, Botrytis cinerea, Rhizobium sp., or Streptomyces) are presented with chlorinated phenolic compounds, which they then convert into chlorinated anisole derivatives.
The Elaeagnaceae often harbor nitrogen-fixing actinomycetes of the genus Frankia in their roots, making them useful for soil reclamation.
