- Abstract
- Crude oil is toxic for most life forms, and environmental pollution by petroleum
hydrocarbons causes major ecological problems, especially in marine environments. Fortunately,
a considerable amount of petroleum entering the sea is eliminated by the activities of
naturally occurring microbial communities. Bacteria such as Alcanivorax spp. provide a major
route for the breakdown of these pollutants, and demonstrate how marine bacteria keep the
environment in check. Of all the Alcanivorax species and other oil-degrading microbes,
Alcanivorax borkumensis is one of the most important worldwide. This obligate hydrocarbonoclastic
bacterium (petroleum hydrocarbons serve almost exclusively as its source of carbon
and energy) is cosmopolitan and found in various marine environments. The whole-genome
sequencing followed by annotation and functional analyses revealed astonishing adaptive
capacities of A. borkumensis. Characteristics that enable A. borkumensis to obtain an ecologically
competitive advantage to both adapt rapidly to the presence of oil and thrive in most
oceans of the world include: its oligotrophic lifestyle and high affinity for hydrocarbon
substrates, biofilm formation at the oil-water interface, niche-specific stress responses, and
its ability to overcome carbon/nutrient imbalances typical of oil spills by specific systems for
scavenging of nutrients, particularly organic and inorganic nitrogen. It degrades a range of
petroleum hydrocarbons and typically dominates oil-degrading microbial communities by
virtue of a combination of streamlined and efficient central metabolic functions and diverse
hydrocarbon degradation and emulsification abilities. (literal)
