Responses of Seawater Bacteria in the Bioremediation Process of Petroleum Contamination by Immobilized Bacteria

A prospective environmental life cycle assessment (LCA) and financial cost assessment is performed to the application of bioaugmentation to sand filters in Danish waterworks, to remove 2,6-dichlorobenzamide (BAM) from drinking water resources. Based on pilot-scale and laboratory-scale data, we compare bioaugmentation to current alternative strategies, namely granular activated carbon (GAC) adsorption, and well re-location. Both assessments identified well re-location as the least preferred option, however, this result is very sensitive to the distance from the waterworks to the new well. When bioaugmentation is compared to GAC, the former has a lower impact in 13 impact categories, but if immobilized bacteria are used, the impacts are higher than for GAC in all impact categories. On the other hand, from a cost perspective bioaugmentation appears to be preferable to GAC only if immobilized bacteria are used.

The article reviewed the advanced methods of ecological floating bed including usage of non-biodegradable bio-carrier, choosen of excellent plants, ion-beam irradiation, immobilized bacteria and aeration. Based on the review, the authors present the idea using biodegrable materials as bio-carrier, which not only could enhance the biomass in the ecological floating bed, but also could overcome the insufficience in carbon source for biological denitrification.

AbstractThree samples of terra rossa were shown to be efficient adsorbents of phosphate [P(V)] from wastewater and removed 29.9–32.6% of P(V). The total iron content in terra rossa was the key factor which determined the P(V) removal from wastewater. The original samples of terra rossa were effective support materials for the immobilization of metabolically active P(V)-accumulating bacteriaAcinetobacter junii(0.56–2.47×1010CFU g–1). The removal of oxalate-extractable iron from original sample of terra rossa increased the number of immobilized bacteria to 1.34×10–11CFU g–1, which is the largest number of immobilized bacteria reported in the literature so far. In reactors containing theA. juniiand terra rossa P(V) was removed from wastewater by simultaneous adsorption onto terra rossa and accumulation inside bacterial cells, resulting in 40.5–62.5% of P(V) removal. Terra rossa is a promising substrate for biological P(V) removal from wastewater, acting both as adsorbent of P(V) and carrier of P(V)-accumulating bacteria.
