Kim, T.H., Lee, J.H., Oh, Y.S., Bae, K.S. and Kim, S.J. (1999) Identification and characterization of an oil-degrading yeast, Yarrowia lipolytica 180. J. Microbiol. 37 (3): 128 - 135
-Among oil-degrading microorganisms isolated from oil-polluted industrial areas, one yeast strain showed high degradation activity of aliphatic hydrocarbons.
-Y. lipolytica has high oil-degrading activity through its high emulsifying activity and cell hydrophobicity, and further indicate that the cell surface is responsible for the metabolism of aliphatic hydrocarbons
Sohn, J.H., Kwon, K.K., Kang, J.H., Jung, H.B. and Kim, S.J. (2004) Novosphingomonas pentaromativorans sp. Nov., a high-molecular-mass polycyclic aromatic hydrocarbon degrading bacterium isolated from estuarine sediment. Int J Syst Evol Microbiol. 54: 1483-1487
-A Gram-negative, yellow-pigmented, halophilic bacterial strain US6-1T, which degrades high-molecular-mass polycyclic aromatic hydrocarbons of two to five rings, was isolated from muddy sediment of Ulsan Bay, Republic of Korea.
Kim, S.J., Choi, D.H., Sim, D.S. and Oh, Y.S. (2005) Evaluation of the bioremediation effectiveness on crude oil contaminated sand Chemosphere. 59 (6): 845-852
-A study was conducted to determine the most effective bioremediation strategies.
-The application of oil-degrading microorganisms in a concentration greater than that of the indigenous population clearly increased biodegradation efficiency.
-The application of surfactant slightly enhanced the oil degradation rate in the contaminated sand treated with the higher concentration of oil-degrading microorganisms.
