The study demonstrates bioremediation as an approach for petroleum hydrocarbon pollution and this pollution is major problem worldwide especially in developing countries like India. Microbial degradation of crude oil components is reported in various chapters, but novelty of this chapter is that the present scenario for oil spill management in India is also discussed in it along with use of microbes in the field of bioremediation, combination of this two is rarely found. This combination will help society to find out way for development of clean and sustainable environment. This chapter throws light on biodegradation as efficient, economic, and eco-friendly treatment. It is prepared for broader readership as language of this paper is very easy to understand. It is subject of many research investigations/thrust areas of research and real-world applications and forms the basis for emergent field of bioremediation.

Crude Oil Spill

Petroleum-hydrocarbon-degrading bacteria were obtained after enrichment on crude oil (as a ‘chocolate mousse’) in a continuous supply of Indonesian seawater amended with nitrogen, phosphorus and iron nutrients. They were related to Alcanivorax and Marinobacter strains, which are ubiquitous petroleum-hydrocarbon-degrading bacteria in marine environments, and to Oceanobacter kriegii (96.4–96.5 % similarities in almost full-length 16S rRNA gene sequences). The Oceanobacter-related bacteria showed high n-alkane-degrading activity, comparable to that of Alcanivorax borkumensis strain SK2. On the other hand, Alcanivorax strains exhibited high activity for branched-alkane degradation and thus could be key bacteria for branched-alkane biodegradation in tropical seas. Oceanobacter-related bacteria became most dominant in microcosms that simulated a crude oil spill event with Indonesian seawater. The dominance was observed in microcosms that were unamended or amended with fertilizer, suggesting that the Oceanobacter-related strains could become dominant in the natural tropical marine environment after an accidental oil spill, and would continue to dominate in the environment after biostimulation. These results suggest that Oceanobacter-related bacteria could be major degraders of petroleum n-alkanes spilt in the tropical sea.

ABSTRACT Understanding initial oil spill responder's exposures is essential for planning purposes and a safe operation; however, there is little relevant information in the literature. Potential oil components of concern include hydrogen sulfide and benzene. This paper uses three dispersion models to evaluate and discuss these potential responder health exposures. Key parameters addressed include the effects of the thickness of the spill and the component concentration in the crude oil. Determination of the amount of time needed for site concentrations to fall below the relevant health guidelines is an important outcome. Model results are compared with available exposure data in the literature. Implications for response planning are discussed.
