“…Variation in salinity is a predominant factor in mangroves and depends on the behaviour of the tides (Ward and Brock 1978;Dott et al 1989, Shiaris 1989Leahy and Colwell 1990;Trevors et al 1994;Kastner et al 1998;Launen et al 2002;Saponaro et al 2002;Tam et al 2002;Olguín et al 2007;Chen et al 2008;Wu et al, 2008;Mnif et al 2009) In some mangroves the most significant factors observed to affect the biodegradation of oil compounds is salinity…”

“…However, these products are not panacea and need to be evaluated according to the requirements of the site before implementation. Dott et al (1989) compared the biodegradability of fuel oil using the commercial product DBC TM (containing nine different dried bacterial mixed cultures) and a mixed culture from a domestic treatment plant during a 31-day incubation period. They asserted that the native microorganisms possessed sufficient biodegradation capability due to eventual adaptations and therefore the rate and extent of biodegradation was higher than that of highly adapted commercial microbial cultures (Dott et al 1989).…”

Later in 1991, Venosa et al conducted a detailed study for the screening of ten commercial products (eight bacterial cultures and 2 non-bacterial products) from ten different companies for the bioremediation of samples from Prince William Sound, Alaska.…”

Bioaugmentation and biostimulation strategies to improve the effectiveness of bioremediation processes

Bioremediation, involving bioaugmentation and/or biostimulation, being an economical and eco-friendly approach, has emerged as the most advantageous soil and water clean-up technique for contaminated sites containing heavy metals and/or organic pollutants. Addition of pre-grown microbial cultures to enhance the degradation of unwanted compounds (bioaugmentation) and/or injection of nutrients and other supplementary components to the native microbial population to induce propagation at a hastened rate (biostimulation), are the most common approaches for in situ bioremediation of accidental spills and chronically contaminated sites worldwide. However, many factors like strain selection, microbial ecology, type of contaminant, environmental constraints, as well as procedures of culture introduction, may lead to their failure. These drawbacks, along with fragmented literature, have opened a gap between laboratory trials and on-field application. The present review discusses the effectiveness as well as the limitations of bioaugmentation and biostimulation processes. A summary of experimental studies both in confined systems under controlled conditions and of real case studies in the field is presented. A comparative account between the two techniques and also the current scenario worldwide for in situ biotreatment using bioaugmentation and biostimulation, are addressed.

“…Atlas and Bartha (1973c) tested several commercial mixtures of oil-degrading bacteria and found that none were superior to the indigenous microorganisms in coastal marine waters. Dott et al (1989) compared nine commercial mixed bacterial cultures to activated sludge microorganisms for their ability to degrade fuel oil in laboratory microcosms. They found that fuel oil degradation by the naturally occurring bacteria in activated sludge did not depend on nor was it enhanced by the application of highly adapted commercially available cultures.…”
