28"Oil-polluted sediment bioremediation depends on both physicochemical and 29" biological parameters, but the effect of the latter cannot be evaluated without the optimization 30" of the former. We aimed in optimizing the physicochemical parameters related to 31" biodegradation by applying an ex-situ landfarming set-up combined with biostimulation to 32" oil-polluted sediment, in order to determine the added effect of bioaugmentation by four 33" allochthonous oil-degrading bacterial consortia in relation to the degradation efficiency of the 34" indigenous community. We monitored hydrocarbon degradation, sediment ecotoxicity and 35"hydrolytic activity, bacterial population sizes and bacterial community dynamics, 36"characterizing the dominant taxa through time and at each treatment. We observed no 37" significant differences in total degradation, but increased ecotoxicity between the different 38" treatments receiving both biostimulation and bioaugmentation and the biostimulated-only 39" control. Moreover, the added allochthonous bacteria quickly perished and were rarely 40" detected, their addition inducing minimal shifts in community structure although it altered the 41" distribution of the residual hydrocarbons in two treatments. Therefore, we concluded that 42" biodegradation was mostly performed by the autochthonous populations while 43" bioaugmentation, in contrast to biostimulation, did not enhance the remediation process. Our 44" results indicate that when environmental conditions are optimized, the indigenous 45" microbiome at a polluted site will likely outperform any allochthonous consortium. 46"47"

“…In wastewater treatment, bioaugmentation has most frequently been applied to aerobic systems to increase the population of nitrifying bacteria after upsets from uncontrolled biomass loss, fluctuations in pH, toxic events, or temperature decrease (Rittmann and Whiteman, 1994;Abeysinghe et al, 2002;Satoh et al, 2003;Head and Oleszkiewicz, 2005). Bioaugmentation has also been used for other aerobic applications, including improved flocculation and degradation of specific substrates (Van Limbergen et al, 1998), and for soil and groundwater bioremediation (Deflaun and Steffan, 2002;Singer et al, 2005).…”

Bioaugmentation for improved recovery of anaerobic digesters after toxicant exposure

et al. 2010

Abstract:Bioaugmentation was investigated as a method to decrease the recovery period of anaerobic digesters exposed to a transient toxic event. Two sets of laboratory-scale digesters (SRT = 10 days, OLR = 2 g COD/Lday),started with inoculum from a digester stabilizing synthetic municipal wastewater solids (MW) and synthetic industrial wastewater (WW), respectively, were transiently exposed to the model toxicant, oxygen.Bioaugmented digesters received 1.2 g VSS/L-day of an H2-utilizing culture NOT THE PUBLISHED VERSION; this is the author's final, peer-reviewed manuscript.

Soon after oxygen exposure, the bioaugmented digesters produced 25-60% more methane than nonbioaugmented controls (p < 0.05). One set of digesters produced lingering high propionate concentrations, and bioaugmentation resulted in significantly shorter recovery periods. The second set of digesters did not display lingering propionate, and bioaugmented digesters recovered at the same time as nonbioaugmented controls. The difference in the effect of bioaugmentation on recovery may be due to differences between microbial communities of the digester inocula originally employed. In conclusion, bioaugmentation with an H2-utilizing culture is a potential tool to decrease the recovery period, decrease propionate concentration, and increase biogas production of some anaerobic digesters after a toxic event. Digesters already containing rapidly adaptable microbial communities may not benefit from bioaugmentation, whereas other digesters with poorly adaptable microbial communities may benefit greatly.

“…The number of petroleum-degrading microbial isolates available for bioaugmentation is increasing (Van Hamme et al 2003;Singer et al 2005). However, the soil environment is very complicated and the degrading ability of exogenously added microorganisms tends to be affected by the physicochemical and biological features of the soil environment.…”

SummaryTwo bacterial species (isolates N and O) were isolated from a paddy soil microcosm that had been artificially contaminated with diesel oil to which extrinsic Pseudomonas aeruginosa, strain WatG, had been added exogenously. One bacterial species (isolate J) was isolated from a similar soil microcosm that had been biostimulated with Luria-Bertani (LB) medium. Isolates N and O, which were tentatively identified as Stenotrophomonas sp. and Ochromonas sp., respectively, by sequencing of their 16 S rRNA genes had no ability to degrade diesel oil on their own in any liquid medium. When each strain was cocultivated with P. aeruginosa strain WatG in liquid mineral salts medium containing 1% diesel oil, isolate N enhanced the degradation of diesel oil by P. aeruginosa strain WatG, but isolate O inhibited it. In contrast, isolate J, which was tentatively identified as a Rhodococcus sp., degraded diesel oil contained not only in liquid LB and mineral salts media, but also in paddy soil microcosms supplemented with LB medium. The bioaugmentation capacity of isolate J in soil microcosms contaminated with diesel oil was much higher than that of P. aeruginosa strain WatG. The possibility of using isolate J for autochthonous bioaugmentation is discussed.
