Resorcinol is biodegradable under aerobic and anaerobic conditions. 

Aerobic:

Several aerobic biodegradation studies are available following inherent and readily biodegradation protocols. In a MITI test following OECD Test guideline 301C, resorcinol was determined to be readily biodegradable with elimination rates being 66.7% after 14 days.  In the study conducted following OECD Test guideline 302B, 97% degradation was observed after 4 days.

Anaerobic:

In a biodegradation study following the Hungate Serum bottle test (Chou et al., 1979; RL =2) resorcinol was considered to have 95% utilization efficiency after 110 days of acclimation.

The Bench Study [Koppers Company, 1982] indicates resorcinol to be biodegradable (99.4% removal) in an ASU considered relevant to industrial Sewage Treatment Plants.
