Cyclodextrin-enhanced biodegradation of phenanthrene
Article Abstract:
The key to efficient in situ bioremediation processing dwells on increasing the bioavailability and enhancing the solubility of toxic substances in order to accelerate their biodegradability rate. It was shown that the addition of analytical grade hydroxypropyl-beta-cyclodextrin (HPCD) tends to hasten the solubility of phenanthrene. The process does not only improve cell growth, but actually increase the substrate utilization rate of the compound, as well.

Nonequilibrium sorption and aerobic biodegradation of dissolved alkylbenzenes during transport in aquifer material: column experiments and evaluation of a coupled-process model
Article Abstract:
The way in which simultaneous biodegradation under aerobic conditions and sorption affected the movement of dissolved alkylbenzenes was studied. The alkylbenzenes were present in a surficial aquifer that had been contaminated by a gasoline spill. A coupled-process model was used to predict simulations. The results indicated that the movement of dissolved alkylbenzenes in columns filled with aquifer material was affected by aerobic biodegradation.

Comment on 'Field-Scale Transport of Nonpolar Organic Solutes in 3-D Heterogenous Aquifers'
Article Abstract:
Criticisms on the model developed by Cushey and Rubin that simulates field-scale groundwater transport of non polar organic compounds using a technique that couples a stochastic technique for generating flow fields with a submodel that describes rate-limited sorption due to mass transfer errs in the estimation of the first-order rate constant. The model also erred in omitting the length-scale correction in the conversion of scenario data.
