“…This implies that proteobacteria has higher tendency to convert most heavy metal in contaminated soil. This finding is agreeable to the results reported by previous bioremediation set-up, for heavy metal contaminated sites [11], [12]. Also, Treatment A recorded the highest removal rate for As (0.01270 day -1 ) and Ni (0.00709 day -1 ).…”

Soil environment is a major sink for a multitude of chemicals and heavy metals, which inevitably leads to environmental contamination problems. Various human activities including agricultural, urban or industrial, or landfilling are major contributors to heavy metal contamination in the environment. Since landfilling is one of the ultimate waste disposal methods, the generation of leachate is inevitable. Leachate from landfill is highly heterogeneous and consist high amount of heavy metal. Subsequent movement of the leachate into the surrounding soil, ground water or surface water could lead to severe pollution problems to and cause toxicity to human and other living organisms. Microorganisms has the ability to solubilize the metals (or increase their bioavailability) via the production of siderophores and adsorb the metals in their biomass on metal-induced outer membrane proteins and by bio precipitation. Therefore this study aimed to remediate heavy metal in leachate contaminated soil from a closed non-sanitary landfill in Kuala Lumpur. Preliminary soil and leachate characterization revealed high amount of metal contaminants as compared to the prescribed limit by local and international standard. Total of eighteen microbes were isolated from the contaminated site and were grouped into two treatments, proteobacteria and non-proteo bacteria.Comparison between the treatments revealed that proteobacteria (Treatment A) were performing higher metal removal activity compared to non-proteobacteria (Treatment B) and control (Treatment C). Out of four metals tested in this study, three of the metals (As (71.86%), Ni (50.8%), Al (87.15%)) were removed significantly by the addition of Treatment A. Highest metal removal rate constant was obtained for Al at 0.02 day -1 . Therefore, it can be concluded that the addition of microbes, namely proteobacteria to leachate contaminated soil can remove the heavy metal content at a significant rate.

“…According their research in nickel-contaminated soils dominate genus Streptomyces (18.1 %) followed by Arthrobacter (15.2 %), Rubrobacter (5.7 %), and Glycomyces (4.8 %) genera. The occurrence of Arthrobacter genus in heavy metal contaminated soil is not surprising and it was reported by several authors (Alvarez et al 2017;Henne et al 2009). The phylum actinobacteria and genus Arthrobacter constitute some of the main and most diverse phyla within the domain Bacteria.…”

“…The advantages of the individual components lies in the providing information on metal binding characteristics of individual organisms, but cannot be directly applied to the behaviour of metals in heterogeneous systems. Studies focused on the behaviour of multi-component systems, like a consortium of microorganisms, represent an approach, even if still simplified, closer to the real situations in which bacteria are found in natural systems (Ledin, 2000;Alvarez et al 2017). These advantages mainly consist of synergistic interactions among members of the consortium.…”

Heavy metal pollution is one of the most important environmental issues of today. Bioremediation by microorganisms is one of technologies extensively used for pollution treatment. In this study, we investigated the heavy metal resistance and zinc bioaccumulation by microbial consortium isolated from nickel sludge disposal site near Sereď (Slovakia). The composition of consortium was analyzed based on MALDI-TOF MS of cultivable bacteria and we have shown that the consortium was dominated by bacteria of genus Arthrobacter. While consortium showed very good growth in the zinc presence, it was able to remove only 15 % of zinc from liquid media. Selected members of consortia have shown lower growth rates in the zinc presence but selected isolates have shown much higher bioaccumulation abilities compared to whole consortium (up to 90 % of zinc removal for NH1 strain). Bioremediation is frequently accelerated through injection of native microbiota into a contaminated area. Based on data obtained in this study, we can conclude that careful selection of native microbiota could lead to the identification of bacteria with increased bioaccumulation abilities.

“…Actinobacteria exhibit various physiological and metabolic properties such as the production of extracellular enzymes further the formation of a wide variety of secondary metabolites including some antibiotics in use today are derived from natural actinobacteria and fungi products (Raju et al, 2010;Porsani, et al, 2013;Manivasagan et al, 2014;Sathiyanarayanan et al, 2014;Rashad et al, 2015;Romano et al, 2016;Dalitz, et al, 2016;Alvarez et al, 2017). In addition, different styles of life are found among actinobacteria thus this phylum includes pathogens (eg.…”

Article InfoMel Island is considered a Natural Historic Site of Paraná State, South Brazil, with approximately 2,760 ha, of which about 95% are protected as the Ecological Station and State Park. This is the first record that evaluates the presence of actinobacteria and fungi in this environment. This research studied the spatial variability of fungi and actinobacteria in the surface of fifteen intertidal stations in Mel Island, Brazil. The number of organisms was compared in relation to physical-chemical factors. We isolated 332 microorganisms. The results showed significance in the temperature of the sediments related to the time of the day on which sample was collected. There were significant differences in the amount of cultivated fungi and actinobacteria. The Principal Component Analysis (PCA) showed that there was an inverse correlation between the number of microorganisms and the temperature. The grain size and organic matter sediment did not interfere in the amount of fungi and actinobacteria. The results show the expansion of the knowledge about the microbiology in the regions between tides furthermore, this microorganisms collected from marine sediment can hold great promise as biological control agents and they might show ability to produce undescribed bioactive compounds yet.
