Biodegradability of Alternative Oxygenates as a Sole Carbon Source or in the Presence of Btex
Abstract:The biodegradability of alkylate compounds in serum bottles was investigated as a sole carbon source or in the presence BTEX. The biomass was acclimated with 2,3-dimethyl pentane (2,3-DMP), 2,4-dimethyl pentane (2,4-DMP) and 2,2,4-trimethyl pentane (2,2,4-TMP) in porous pot reactors. The alkylates (2,3-DMP, 2,4-DMP, and 2,2,4-TMP) were completely biodegraded in all the sets of experiments. When they were present with BTEX, alkylates degraded slower than when they were alone because BTEX inhibited the microbial utilization of alkylates. Throughout the experiments alkylates and BTEX concentrations did not change in the biologically inhibited controls.
