Enhanced in situ bioremediation of phenol in bioestimulated unsaturated and saturated sand-bed columns.


Biodegradation of phenol was observed in unsaturated sandbed columns, in which phenol concentration declined from 298 mg phenol/kg sand to less than 1 mg/kg after 21 days. In saturated sand-bed columns, phenol concentration declined from 230 mg phenol/kg to less than 1 mg/kg after 37 days. Pseudo-first-order phenol biodegradation rates were in the range 0… (More)
