The technological developments currently witnessed in the world regarding the utilization of
hydrocarbon related products have increasingly brought about all forms of hydrocarbon related environmental
pollution. This current review documents the influence of hydrocarbon utilizing microorganisms in bringing about
biodegradation of spent engine oil and other petroleum related environmental pollution. Hydrocarbonoclastic bacteria
and fungi when given optimum environmental conditions and nutritional requirements have been documented to
bring about effective bioremediation of oil polluted environments. This review has compiled the monumental
influence of hydrocarbonoclastic microorganisms most especially bacteria and fungi in aiding bioremediation of
spent engine oil and other petroleum related environmental pollution.
Pseudomonas alcaligenes
LR14 (59%),
Klebsiella aerogenes
CR21 (62%),
Klebsiella pneumoniae
CR23 (58%),
Bacillus coagulans
CR31 (45%) and
Pseudomonas putrefacience CR33 (68%) reportedly exhibited spent engine oil polluted soil degradation rate while
Fungi like
Aspergillus
,
Cephalosporium
and
Pencillium
species were also found to be the potential microorganisms
responsible for hydrocarbon bioremediation. This current review, equally documents the environmental and
nutritional requirements needed by these hydrocarbon oxidizers to accomplish the desired bioremediation process.
