“…It seems that the fungal species used oil compounds as nutrients and petroleum pollution cause to increase fungal growth. The similar results were reported by some researchers [11,16-21]. Penicillium oxalicum was also isolated from petroleum-polluted soils and reported as degradability potential microorganism for bioremediation of crude oil [34].…”

“…Chemical composition of the used crude oil in the refinery is 13.4% saturated hydrocarbons, 40% aromatic hydrocarbons, 46.6% polar compounds (Refinery office data). Due the oil refining activities in this region, a high degree of petroleum pollution (5-10%) was reported in the refinery areas [16]. The identification of soil contamination was also possible based on a visual examination of the soil.…”

“…The Petri dishes were incubated in 25 ± 2°C for 4 days. Then, different fungal colony were isolated and cultured separately in PDA [16]. Fungal specimens were examined under light microscope after preparations and identified using morphological characters and taxonomical keys provided in the mycological keys [26-28].…”

BackgroundPetroleum pollution is a global disaster and there are several soil cleaning methods including bioremediation.MethodsIn a field study, fugal strains were isolated from oil-contaminated sites of Arak refinery (Iran) and their growth ability was checked in potato dextrose agar (PDA) media containing 0-10% v/v crude oil, the activity of three enzymes (Catalase, Peroxidase and Phenol Oxidase) was evaluated in the fungal colonies and bioremediation ability of the fungi was checked in the experimental pots containing 3 kg sterilized soil and different concentrations of petroleum (0-10% w/w).ResultsFour fungal strains, Acromonium sp., Alternaria sp., Aspergillus terreus and Penicillium sp., were selected as the most resistant ones. They were able to growth in the subjected concentrations and Alternaria sp. showed the highest growth ability in the petroleum containing media. The enzyme assay showed that the enzymatic activity was increased in the oil-contaminated media. Bioremediation results showed that the studied fungi were able to decrease petroleum pollution. The highest petroleum removing efficiency of Aspergillus terreus, Penicillium sp., Alternaria sp. and Acromonium sp. was evaluated in the 10%, 8%, 8% and 2% petroleum pollution respectively.ConclusionsFungi are important microorganisms in decreasing of petroleum pollution. They have bioremediation potency that is related to their enzymatic activities.

BackgroundEnvironment pollution by heavy metals is a global disaster and there are several cleaning methods including bioremediation. Trichoderma species inhibit the growth of pathogenic fungi and play a useful role in agriculture and ecosystem management.MethodsIn this study, the removing of cadmium ions by three species of Trichoderma (T. asperellum, T. harzianum and T. tomentosum) were studied under different pH (5, 7, 9) and different concentrations of Cd (1, 100, 200 ppm) in liquid media containing potato extract and dextrose. Above mentioned fungal strains were cultured in the Cd-polluted media and the remaining amount of metal ions in the media was measured after two months growth, using atomic absorption.ResultsResults showed that all three fungal species were able to reduce the amount of Cd in the all three pH of the medias; but their removal ability varies depending on the species and cultural conditions. T. asperellum was showed maximum removal efficiency of cadmium (76.17%), (10.75 mg/g, at fungal dry weight). Based on our results, the most removal efficiency of Cd ions for the fungal species was evaluated in the alkaline pH.ConclusionsTrichoderma species are important fungi in decreasing of Cadmium ions. They have bioremediation potency under various pH and concentration conditions.

Environmental Contamination Remediation and Management

Due to human activity and, to a lesser extent, natural processes, petroleum hydrocarbons continue to pollute the environment. These contaminants of concern can be found globally and their remediation is key to restoring affected sites to safe and functional status. Conventional treatment of sites contaminated with petroleum hydrocarbons relies heavily on remediation approaches that are often financially prohibitive or may be technically impractical and that sometimes produce undesirable by-products. Using microbes that occur in nature (if not always at the site), can be a viable treatment with distinct advantages. Understanding the environment, contaminants, and natural biological processes occurring are key aspects for effective application of remediation techniques that rely on biological processes. Whether by stimulating the native microbial community, or, secondarily, by augmenting the native community with known degrader populations to degrade the target compounds, bioremediation is a practical, effective, and sustainable natural solution to a wide array of contamination around the globe. This chapter explores approaches to bioremediation of both soil and groundwater contaminated by petroleum hydrocarbons, describing how the approaches work and the benefits and challenges associated with them. It focuses on the use of aerobic and anaerobic microbial bioremediation, phytoremediation, and mycoremediation to address petroleum hydrocarbons.
