“…Other than degradation tests in the laboratory, which were employed to predict degradation performance and to identify degradation limitations present in soil, in situ respiration tests were used to estimate biodegradation potential and to consider site conditions. Besides, observed respiration rates -corrected by values for background respirationcan be used for the calculation of hydrocarbon biodegradation (Baker et al 2000;Miles & Doucette 2001). Oxygen utilisation rates greater that 1% day )1 are a good indicator that bioventing may be feasible at a site (Leeson & Hinchee 1997).…”

“…In situ respiration tests determine biodegradability potential indirectly via O 2 consumption or CO 2 production in the field (Balba et al 1998). Rates then have to be corrected by background respiration result from biodegradation of organic substances and other oxygen consuming processes (Baker et al 2000). Field tests consider site conditions comprising local heterogeneity and changing environmental conditions.…”

“…Permeability in the subsoil is rarely uniform but typically reveals significant local differences that can only be assessed in situ (Davis et al 2003). By the application of preliminary field tests, relevant information can be deducted on the definite system design including actual flow rates, radii of influence, blower and well layout (Leeson & Hinchee 1997;Baker et al 2000;Ho¨hener et al 2003).…”

Preliminary tests at different scales such as degradation experiments (laboratory) in shaking flasks, soil columns and lysimeters as well as in situ respiration tests (field) were performed with soil from two hydrocarbon contaminated sites. Tests have been evaluated in terms of their potential to provide information on feasibility, degradation rates and residual concentration of bioremediation in the vadose zone. Sample size, costs and duration increased with experimental scale in the order shaking flasks - soil columns - lysimeter - in situ respiration tests, only time demand of respiration tests was relatively low. First-order rate constants observed in degradation experiments exhibited significant differences between both, different experimental sizes and different soils. Rates were in line with type and history of contamination at the sites, but somewhat overestimated field rates particularly in small scale experiments. All laboratory experiments allowed an estimation of residual concentrations after remediation. In situ respiration tests were found to be an appropriate pre-testing and monitoring tool for bioventing although residual concentrations cannot be predicted from in situ respiration tests. Moreover, this method does not account for potential limitations that might hamper biodegradation in the longer term but only reflects the actual degradation potential when the test is performed.

“…Most of the studies on PHC mineralization made so far have focused on (i) identifying the microbial community structure capable of degrading PHC (Grishchenkov et al 2000;Kao et al 2001;Kleikemper et al 2002b;Nakagawa et al 2002), (ii) evidence for mineralization of specific PHC compounds by sulfate reducers (Beller et al 1992;Edwards et al 1992;Somsamak et al 2001;Coates et al 2002), (iii) rate of oxidation of PHC with various terminal electron acceptors (Hunkeler et al 1998;Baker et al 2000;Johnson et al 2003;Villatoro-Monzó n et al 2003;Maliyekkal et al 2004) or (iv) the rate of sulfate reduction with PHC as electron donor (Aharon and Fu 2000;Shin et al 2000). Furthermore, many of these studies are based on enrichment culture work under optimum laboratory conditions for microbial growth, which may not be relevant to field situations.…”

An integrated field and laboratory study was conducted to quantify the effect of environmental determinants on the activity of sulfate reducers in a freshwater aquifer contaminated with petroleum hydrocarbons (PHC). Within the contaminated zone, PHC-supported in situ sulfate reduction rates varied from 11.58 ± 3.12 to 636 ± 53 nmol cm -3 d -1 and a linear increase (R 2 =0.98) in reduction rate was observed with increasing in situ sulfate concentrations suggesting sulfate limitation. Half-saturation concentration (K s ) for sulfate reduction coupled to PHC mineralization was determined for the first time. At two different sites within the aquifer, maximum sulfate reduction rate under non-limiting conditions (R max ) was 5,000 nmol cm -3 d -1 , whereas the retrieved K s values were 3.5 and 7.5 mM, respectively. The K s values are the highest ever reported from a natural environment. Furthermore, the K s values were significantly higher than in situ sulfate concentrations confirming sulfate limited growth. On addition of lactate and formate, sulfate reduction rate increased indicating that reactivity and bioavailability of organic substrate may also have played a role in rate inhibition in certain parts of the aquifer. Experiments with sulfide amendments show statistically minor decrease in sulfate reduction rates on addition of sulfide and analogous increase in sulfide toxicity with increasing sulfide concentrations (0.5-10 mM) was not apparent.

“…Research in bioremediation is often focused on ex-situ bench-scale studies as such setups facilitate control of important experimental parameters such as temperature and pH. Previous studies on ex-situ bench-scale bioremediation include biodegradation of hydrocarbon petroleum contaminated soil [1], gasoline-contaminated sediments [2] and diesel-contaminated soil [3].…”

This paper presents a bench-scale study of bioremediation of soil contaminated with maleic anhydride. A quantity of 300 kg of contaminated soil was collected from a petrochemical plant in Malaysia and divided into three portions in order to investigate the effects of nutrient addition as well as mechanical aeration on the biodegradation rate of the contaminants. Online parameters measured included moisture content, redox potential, temperature and pH. The highest first-order biodegradation rate constant was determined to be 6.658 day -1 for soil pile with addition of nutrients and mechanical aeration.
