“…These chemicals can be hazardous to human health, and include known mutagens and carcinogens (Haritash and Kaushik 2009). ULO generated from mechanical workshops is becoming a major environmental problem in Thailand (Naladta and Milintawisamai 2011; Pimda and Bunnag 2012; Saimmai et al 2012) due to inaccessibility of proper disposal facilities and improper disposal.…”

Used lubricating oil (ULO) is a widespread contaminant, particularly throughout tropical regions, and may be a candidate for bioremediation. However, little is known about the biodegradation potential or basic microbial ecology of ULO-contaminated soils. This study aims to determine the effects of used lubricating oil (ULO) on bacterial community structure and diversity. Using a combination of culture-based (agar plate counts) and molecular techniques (16S rRNA gene sequencing and DGGE), we investigated changes in soil bacterial communities from three different ULO-contaminated soils collected from motorcycle mechanical workshops (soil A, B, and C). We further explored the relationship between bacterial community structure, physiochemical soil parameters, and ULO composition in three ULO-contaminated soils. Results indicated that the three investigated soils had different community structures, which may be a result of the different ULO characteristics and physiochemical soil parameters of each site. Soil C had the highest ULO concentration and also the greatest diversity and richness of bacteria, which may be a result of higher nutrient retention, organic matter and cation exchange capacity (CEC), as well as freshness of oil compared to the other soils. In soils A and B, Proteobacteria (esp. Gammaproteobacteria) dominated the bacterial community, and in soil C, Actinobacteria and Firmicutes dominated. The genus Enterobacter, a member of the class Gammaproteobacteria, is known to include ULO-degraders, and this genus was the only one found in all three soils, suggesting that it could play a key role in the in situ degradation of ULO-contaminated tropical Thai soils. This study provides insights into our understanding of soil microbial richness, diversity, composition and structure in tropical ULO-contaminated soils, and may be useful for the development of strategies to improve bioremediation.

Nano-enhanced Bioremediation for Oil Spills: A Review

2021

View full text Add to dashboard Cite

Oil seepage and spills have lasting detrimental effects on the environment, especially on nearby marine ecosystems. Despite quick and safe removal of contaminating oil being of utmost importance, remediation methods have remained largely unchanged over the last 20+ years. Removal methods such as skimmers, in situ burning, and sorbents can be difficult to implement in inclement weather. Marine microorganisms consume spilled oil as a primary energy source in a method known as bioremediation. Recently the introduction of nanoparticles to areas contaminated by oil has emerged as a potential method to enhance the efficacy of oil degradation by marine microorganisms. Nanoparticles have been primarily utilized as magnetic sorbents but can also act as emulsifiers, increasing the bioavailability of the oil by giving microbes a surface (droplets) to which they can attach and facilitate proliferation. Emulsification increases the oil−water interfacial area and often leads to an increase in the amount of oil degraded by microorganisms. Nanoenhanced bioremediation is effective on a variety of oil compositions and is minimally impacted by weather. It offers a sustainable alternative to traditional remediation methods, i.e., chemical dispersants, sorbents, and in situ burning, which are often toxic and ineffective.
