“…A supply of the highly soluble H 2 O 2 to produce 0 2 by catalytic decomposition can lead to toxic effects, to an oversaturation with 0 2 and to a clogging of the aquifer by 0 2 bubbles (Spain et al, 1989;Hinchee et al, 1991;Pardieck et al, 1992). Although petroleum hydrocarbons are most readily degraded under aerobic conditions (Atlas and Bartha, 1992), it has been demonstrated that a complete mineralization of a number of hydrocarbons also occurs under denitrifying (Zeyer et al, 1986), iron-reducing (Lovley and Lonergan, 1990), sulfate-reducing (Aeckersberg et al, 1991) and methanogenic conditions (Edwards and Grbic-Galic, 1994). This opens the attractive opportunity to supply, for example, NO 3 to the contaminated zone.…”

The in situ bioremediation of aquifers contaminated with petroleum hydrocarbons is commonly based on the infiltration of groundwater supplemented with oxidants (e.g., 0 2 , N0 3 ) and nutrients (e.g., NH1, Pol-). These additions stimulate the microbial activity in the aquifer and several field studies describing the resulting processes have been published. However, due to the heterogeneity of the subsurface and due to the limited number of observation wells usually available, these field data do not offer a sufficient spatial and temporal resolution. In this study, flow-through columns of 47-cm length equipped with 17 sampling ports were filled with homogeneously contaminated aquifer material from a diesel fuel contaminated in situ bioremedia tion site. The columns were operated over 96 days at 12°C with artificial groundwater supple mented with 0 2 , N0 3 and POJ-. Concentration profiles of 0 2 , N0 3 , N0 2 , dissolved inorganic and organic carbon (DIC and DOC, respectively), protein, microbial cells and total residual hydrocarbons were measured. Within the first 12 cm, corresponding to a mean groundwater residence time of < 3.6 h, a steep 0 2 decrease from 4.6 to < 0.3 mg 1-1 , denitrification, a production of DIC and DOC, high microbial cell numbers and a high removal of hydrocarbons were observed. Within a distance of 24 to 40.5 cm from the infiltration, 0 2 was below 0.1 mg 1-1 and a denitrifying activity was found. In the presence and in the absence of 0 2 , n-alkanes were preferentially degraded compared to branched alkanes. The results demonstrate that: (1) infiltra tion of aerobic groundwater into columns filled with aquifer material contaminated with hydrocar bons leads to a rapid depletion of 0 2 ; (2) 0 2 and N0 3 can serve as oxidants for the mineralization of hydrocarbons; and (3) the modelling of redox processes in aquifers has to consider denitrifying activity in presence of 0 2 .

“…The soil phosphorus was in the range of 1.5 to 5.8 mg.Kg -1 . The optimum C:N:P ratio in soil is critical for biodegradation of petroleum hydrocarbon as microorganisms utilize these elements for incorporation into biomass and the synthesis of cellular components (Atlas & Bartha 1992, Stroud et al 2007. The water holding capacity or the presence of moisture level is one of the essential parameters for the biodegradation of crude oil at the optimum level.…”

Abstract:The Screening of native fungi from crude oil contaminated soil of Assam is conducted. Total crude oil concentrations varied from 39000 mg.Kg -1 to 51500 mg.Kg -1 . The soil fungal population varied from 14.6×10 6 CFU.g -1 to 19.2×10 6 CFU.g -1 soil. Twenty fungal strains were isolated and out of them seven were selected on the basis of their ability to grow in PDA medium where crude oil is used as sole carbon source. The growth rate and tolerance of each strain to crude oil were examined and were found quite satisfactory. The radial extension rate varied from 0.03 cm.d −1 to 0.50 cm.d −1 and exhibited significant differences (P< 0.01) among the selected strains.The degradation percentage of crude oil was in the range of 71% to 89% in mineral salt medium (MSL) after the incubation for 28 days showing outstanding potential of isolates.

“…Hydrocarbon degrading bacteria and fungi are widely distributed in marine, fresh water, and soil habitats (Atlas and Bartha, 1992), The most prevalent hydrocarbon degrading bacteria in the soil environment are Pseudomonas, Arthrobacter, Micrococcus, Nocardia, Vibrio, Acinetobacter, Rhodococcus, Corynebacterium, Sphingomonas, and Mycobacterium (Bartha and Atlas, 1977;Atlas and Bartha, 1992;Korda et al, 1997). A number of hydrocarbon degrading Pseudomonas species has been isolated from oil contaminated Antarctic soils (Mac Cormack and Fraile, 1997) and Kerry (1990) and Aislabie (1997) found that numbers of Antarctic hydrocarbon degrading bacteria were enhanced in fuel contaminated Antarctic soils compared to pristine Antarctic soils.…”
