“…These variations depended on various factors such as the initial concentration of the target pollutant or the culture conditions such as type of medium, pH or temperature and the bioavailability of the pollutant. It was also observed that the percentage of PAH biodegradation was significantly higher in liquid than in solid culture conditions, probably due to the decreased PAH availability in solid medium [34,35] . Even so, there are some studies on solid cultures that demonstrate higher degradation rates (Table 1), probably due to the effect of the different factors mentioned above [14,17,36] .…”

The efficiency of cork waste in adsorbing aqueous polycyclic aromatic hydrocarbons (PAHs) has been previously reported. Biodegradation of contaminated cork using filamentous fungi could be a good alternative for detoxifying cork to facilitate its final processing. For this purpose, the degradation efficiency of anthracene by three ligninolytic white-rot fungi (Phanerochaete chrysosporium, Irpex lacteus and Pleurotus ostreatus) and three non-ligninolytic fungi which are found in the cork itself (Aspergillus niger, Penicillium simplicissimum and Mucor racemosus) are compared.Anthracene degradation by all fungi was examined in solid-phase cultures after 0, 16, 30 and 61 days. The degradation products of anthracene by P. simplicissimum and I. lacteus were also identified by GC-MS and a metabolic pathway was proposed for P. simplicissimum.Results shown that all the fungi tested degraded anthracene. After 61 days of incubation approximately 86%, 40% and 38% of the initial concentration of anthracene (i.e. 100 µM) was degraded by P. simplicissimum, P. chrysosporium and I. lacteus, respectively.The rest of the fungi degraded anthracene to a lesser extent (< 30%). As a final remark, the results obtained in this study indicate that P. simplicissimum, a non-ligninolytic fungi characteristic of cork itself, could be used as an efficient degrader of PAHcontaminated cork.

“…However, bioremediation is the perfect tool for hazardous compounds with less input of chemicals, energy and time, using suitable microbes (Yuan et al, 2002). Recently, the synergistic use of plants and microbes to clean up the PAH-contaminated soil generated encouraging results (Glick, 2003;Huang et al, 2004), as the rhizosphere of plant provides better environment for bacteria to survive and proliferate (Yee et al, 1998).…”

Four bacterial strains viz. Kurthia sp. SBA4, Micrococcus varians SBA8, Deinococcus radiodurans SBA6 and Bacillus circulans SBA12 identified as Polyaromatic hydrocarbons (PAH) degrader, isolated form the rhizospheric soil of Populus deltoides growing in non-contaminated sites of Uttarakhand Himalyan region, India. Out of these four isolates, M. varians SBA8 degraded appreciable amount of PAH along with some plant growth promoting properties viz. indole acetic acid (IAA) 19 µg ml -1 , phosphate solubilization 1.8 µg ml -1 , produced siderophore and possessed ACC deaminase activity. Along with these traits, M. varians SBA8 also exhibited biocontrol activities against phytopathogenic fungi Rhizoctonia solanii, Macrophomina phaseolina and Fusarium oxysporum with 50, 43.3 and 34.6 percent growth inhibition (PGI). Moreover, mycelial deformities were also observed in the test fungal spp. The M. varians SBA8 proved to be competent rhizobacteria in rhizosphere niche in treatments T 1 (Sterile soil + plant cuttings + bacterization) and T 2 (sterile soil + anthracene + plant cuttings + bacterization). Rhizoremediation potential of M. varians SBA8 was also determined in PAH amended soil model system. Significant enhancement in shoot, root length, root and shoot biomass including stem girth of P. deltoides with respect to control was recorded and concurrently the bacterium degraded 43.6 % of PAH as determined by HPLC analysis in soil model system after 120 days of inoculation. Multipurpose inoculant was also formulated using M. varians SBA8 strain immobilized in different lignocellulosic waste material used as carriers. Rock phosphate, cocoa peat and wheat bran based bioinoculant were found suitable for rhizoremediation of PAH.

“…Some products of this degradation pathway were analyzed (Cis-4,5-pyrene dihydrodiol, 4-5-phenanthrene dicarboxylic acid, 1-hydroxy-2-naphthoic acid, 2-carboxybenzaldehyde, phthalic acid, and protocatechuic acid). In the study of Yuan et al [11], the authors isolated strains of bacteria from a petrochemical waste which having the capacity [27]. The study also proposed the degradation pathway of fluoranthene.…”

Soil Contamination - Current Consequences and Further Solutions

Soil contamination could adversely affect microbial diversity, and perhaps also aboveand below-ground ecosystem functioning. It is important to study microbial diversity not only for basic scientific research, but also to understand the link between diversity and community structure and function in the pollution site. The study of microbial diversity and their function in contaminated soil creates a serious problem because they observed significant limitations in methodology and taxonomy of this group. Methodology for the determination of bacterial diversity does not include their function in the soil and other environment areas. Microbes are known for their catabolic activity in bioremediation, but changes in microbial communities are still unpredictable. The bioremediation of a pollutant and its rate depend on the environmental conditions, number and type of the microorganisms, nature and chemical structure of the chemical compound being degraded. However, molecular methods have been used to study soil bacterial communities. While many anthropogenic activities, such as city development, agriculture, and use of pollution, can potentially affect soil microbial diversity, it is unknown how changes in microbial diversity can influence below-ground and aboveground ecosystems. There are problems associated with studying bacterial diversity in soil. These arise not only from methodological limitations, but also from a lack of taxonomic knowledge. Methods to measure microbial diversity in soil can be categorized into two groups: biochemical-based techniques and molecular-based techniques. But more common for studying microbial diversity in soil contaminated with polycyclic aromatic hydrocarbons are the molecular methods.
