“…[3], that the impact of hydrocarbon on the acidity of soil as it prevents leaching of basic salts as well as leads to production of organic acids. There was a distinct increase in soil pH when samples were taken five days after contamination, [9] had previously reported that such variability in soil pH which could arise during organic decay processes which may result in the formation of both acid and base forming chemicals.…”

“…The attendant negative consequences of physicochemical methods of oil degradation make biological alternative or biodegradation more attractive. It is cost-effective and does not involve high skilled technology, making it acceptable and suitable for all countries of the world [3]. Despite the great advantages of bioremediation, this approach is now used in only about 5% of all soil treatments.…”

Environmental pollution is one of the major hazards facing humanity in the quest for energy today. In Nigeria, the activities of oil exploration and exploitation have repeatedly exposed the environment to the effect of hydrocarbon spill. This research work was carried out to investigate the potential of activated carbon produced from coconut shell to treat Escravous crude oil contaminated soil, by varying pollutant dosage, adsorbent dosage and time. The present study has clearly demonstrated that activated carbon from coconut shell (ACCS) can be used to significantly enhance the rate of degradation of petroleum hydrocarbon in the soil when homogenized with water in a ratio of 20 w/w and studied under an atmospheric temperature. A significant degradation was achieved after 32 days of the remediation process. When the soil to ACCS ratio and crude oil to ACCS were 48 w/w, and 1 mL/g respectively, (AX1) sample code had a ratio of crude to ACCS as 1:1, which reduces the total petroleum hydrocarbon (TPH) from 43.56 to 18.78 residue (mg/L). TPH was also observed to reduce to 2.83 mg/L from initial concentration of 28.92 mg/L when ratio of crude oil to ACCS was 1:1.5 (BX1) sample code, while reduction in THP of 13.63 mL was achieved with 0.5:1.5 ratio of crude oil to ACCS (CX1) sample code. The three (3) results had their rate and percentage of remediation for AX1, BX1, and CX1 as 0.77, 0.82 and 0.43 (mg/L)/day and 56.88%, 90.22% and 92.97% respectively. BX1 approach with the ratio of 1:1.5 has the high rate and percentage remediation more promising compared to AX1 and CX1. Lead which is a big treat to both plants and animals was almost reduced to a Zero (0) percentage.

“…Segundo Yakubu (2007), o termo biorremediação pode ser definido como um processo biotecnológico no qual se utiliza o metabolismo de micro-organismos para a eliminação rápida de poluentes, com o objetivo de reduzir sua concentração a níveis aceitáveis, transformado-os em compostos de baixa toxicidade.…”

RESUMO Nas últimas décadas, os problemas ambientais têm se tornado cada vez mais críticos e frequentes, principalmente devido ao desmedido crescimento populacional e ao aumento da atividade industrial. A observação de como o meio ambiente reage a cada intervenção antropogênica mostra a atuação de micro-organismos na busca da autopreservação, degradando os poluentes e utilizando-os como fonte de nutrientes. O uso de micro-organismos como ferramentas para a remediação de ambientes contaminados é chamada de biorremediação. Neste presente artigo, pretendeu-se reunir trabalhos que justifiquem a utilização de micro-organismos como uma alternativa biológica viável para a remediação de ambientes contaminados, visando a utilização deste paper como ferramenta didática para a educação ambiental em ambientes universitários. Palavras-chave: Biodegradação. Micro-organismos. Poluentes. Educação Ambiental ABSTRACT In the last decade the environment problems have being more critical and frequent, mainly due to the population growth and the increase of industrial activities. The observation of microbial answer to the human environmental intervention, shows the capacity of these organisms in degrading the pollutant and its utilization as source of nutrients. Therefore, the use of microorganisms in degrading the pollutant presents in polluted areas is called bioremediation. The main of these project is join some papers that justify the use of microorganisms in the remediation of polluted areas, as a didactic tool in the environmental education at universities. INTRODUÇÃO Nas últimas décadas, os problemas ambientais têm se tornado cada vez mais críticos e frequentes, principalmente devido ao desmedido crescimento populacional e ao aumento da atividade industrial. Com estes ingredientes, os problemas devido à ação antrópica têm atingido dimensões catastróficas, podendo ser observados por meio de alterações na qualidade do solo, do ar e da água (FREIRE et al., 2000). As atividades industriais atraíram novos problemas devido à eliminação de rejeitos tóxicos provenientes de subprodutos gerados pelas indústrias. A eliminação desses produtos é, atualmente, um dos mais importantes assuntos em controle de poluição, o que tem levado os pesquisadores a buscarem novas técnicas e ferramentas mais poderosas que visem à remoção desses compostos do ambiente (ANDRADE, 2003). A observação de como o meio ambiente reage a cada intervenção antropogênica mostra a atuação de micro-organismos na busca da autopreservação, degradando diversos poluentes e

“…Hydrocarbon degradative process is widely distributed among numerous genera or taxa [14] and biodegradation of hydrocarbons using microorganisms has been established as an efficient, economic and versatile approach [15][16][17][18][19]. Microorganisms degrade hydrocarbon contaminants and utilize the resulting compounds as nutrients and energy sources for growth and reproduction [20] and are depending on the chemical nature of the compounds and on environmental determinants [21].…”

Polycyclic aromatic hydrocarbons (PAHs) are common environmental pollutants and biodegradation using microorganisms is the preferred and major route of PAH removal from contaminated environments. This study investigated the bacterial degradation of petrol and diesel in liquid media that were isolated from oil contaminated soils by enrichment technique. The isolates could use petrol and diesel as their sole carbon and energy source in Bushnell Hass Mineral Salts (BHMS) medium at 2% (v/v) concentration. A total of eight isolates were selected and characterized by using a variety of phenotypic and morphologic properties. Two isolates each showed highest growth in petrol and diesel containing media during screening were selected and characterized using 16S RNA sequencing. Molecular identification of the isolates assigned them to Achromobacter sp. and Pseudomonas aeruginosa. The selected isolates degraded petrol and diesel up to 31.9% and 34.4% respectively. This study indicates that the contaminated soil samples contain a diverse population of PAH-degrading bacteria and the use of Achromobacter sp. and Pseduomonas aeruginosa has the potential for bioremediation of PAH contaminated sites.
