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"

“…All the bacterial species belong to the γ-proteobacteria group and represent a core component of native bacteria community often found in soil and on phylogenetic tree [3]. Hence, there is no anticipation that utilizing such microbes in bioremediation will cause significant alteration to the normal microbial structure in the soil.…”

“…Hence, this is the reason bioremediation of leachate-metal polluted soil is very important. A sustainable soil remediation approach is any method that involves technical removal of pollutants while soil quality and functioning are preserved [2], [3]. Basically, bioremediation is primarily the use of degrader microbes, but the toxic level of contaminants within a polluted soil environment may only allow the survival of some microbes rather than giving chance for pollutant degradation (in case of most organic compounds) or transformation (in case of most inorganic compounds like metals) [4].…”

Bioremediation of metal contaminated soil involves complex processes, and the non-degradable nature of metals makes it more difficult. The known sources of metal pollution are many and adopting a specific remediation procedure for it is often impossible. Microbes found at polluted sites tend to serve as good remediation agents due to perceived environmental potential. Therefore, it is imperative to select bioremediation by enhancing microbes potential as a way of restoring metal polluted site to original or undisturbed state. Hence, this study tried to evaluate the individual effect of bacterial isolates on the remediation of metal polluted soil from landfill, against combined impact of microbes blended together. Soil samples that characterized of Cd 2+ , Cr 2+ , Pb 2+ and Zn 2+ were subjected to bioremediation. Results revealed no more than 50% reduction across the treatments amended with individual isolates. Rather higher metal remediation was observed when individual isolates were mixed prior to application. Therefore, the study suggests that individual isolates from contaminated sites can selectively metabolize to bioreduce metal concentrations. However, a mix of such isolates with manipulation in the concentration level can enhance metal reduction efficiency (>50%).

“…Soil samples were collected from Taman Beringin (TBL) (30 13.78Ń; 1010 39.72É; non-operational) landfills at 30cm depth in accordance with the 2014 ASTME-1197 [9], [10], and [11]. The sample were analyzed for pH using a multiprobe meter (YSI Professional Plus, USA), while the soil total nitrogen, total potassium, and total phosphorus were analyzed by adopting ASTM E778-87, ASTM E96-94, and ASTM D5198-92 methods, respectively.…”

Abstract-Heavy metals are extremely persistent in the environment and cannot degrade through chemical process, hence the long term accumulation cause induce to the environment. Soil is one of the major sink to heavy metal contamination due human activities associated to the development of global economies. Metals from waste stream, especially landfill leachate impact the soil and there is need to develop remedial option for the environmental safety of soil core. Various plants have been used to remedy polluted soil, yet metal interaction with plant differ with respect to medium or source of metal pollution. Phytoremediation technology is an alternative and cheaper approach for remediation of metal contaminated soil. Plant-based remediation is one of the most significant sustainable techniques to cope with overwhelming consequences of pollutants. Therefore this study aimed to study the potential of Cordyline sp plant and Durianta variegated for the phytoremediation of heavy metals (Pb, As, Mn, Ni, and Cr) from the leachate contaminated soil. The results showed that Cordyline sp plants tends to accumulate high amounts of this metals compared to Durianta variegated and control. Cordyline sp was able to remove 63 % of Pb, 90 % of As, 78.8 % of Mn, 88.9 % of Ni and 75 % of Cr from the metal polluted soil. The removal of heavy metal from the contaminated soil was significantly higher compared to control at P > 0.05. The highest heavy metal removal rate constant was obtained for As and Ni at same rate of 0.018 mg/kg day -1 when Cordyline sp plants were used. Therefore we can conclude that, Cordyline sp have a potential to remediate heavy metal contaminated soil at a significant level.
