Mercury-resistant bacteria and petroleum degradation
Applied Microbiology
|January 1, 1974
Summary
Mercury concentration in oil from Colgate Creek was significantly higher than in water or sediment. Mercury-resistant bacteria in the creek may play a key role in oil degradation.
Area of Science:
- Environmental Science
- Environmental Chemistry
- Microbiology
Background:
- Colgate Creek in Baltimore Harbor is a site of environmental concern.
- Mercury contamination in aquatic ecosystems poses risks.
- Oil spills can be exacerbated by the presence of heavy metals.
Purpose of the Study:
- To determine mercury concentrations in water, sediment, and extracted oil from Colgate Creek.
- To investigate the relationship between mercury levels and oil degradation.
- To assess the role of mercury-resistant bacteria in oil biodegradation.
Main Methods:
- Sample collection from Colgate Creek.
- Mercury concentration analysis in water, sediment, and oil.
- Identification and assessment of mercury-resistant bacterial populations.
- Evaluation of bacterial oil degradation capabilities.
Main Results:
- Mercury concentration in oil was 4,000 times higher than in sediment.
- Mercury concentration in oil was 300,000 times higher than in water.
- Mercury-resistant bacteria capable of oil degradation were identified in the samples.
Conclusions:
- The high mercury concentration in oil suggests a significant environmental hazard.
- Mercury-resistant bacteria are likely crucial for oil degradation in Colgate Creek.
- Further research into bioremediation strategies using these bacteria is warranted.

Bioremediation
Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.
Marine Microbial Ecology
Marine microbial ecosystems are shaped by distinct physicochemical limits, including high salinity, low nutrient availability, and fluctuating oxygen levels. These conditions favor smaller microbial cell sizes, which maximize their surface-to-volume ratio for efficient nutrient uptake.Microbial activity and community composition are closely linked to biogeochemical cycles, particularly in dynamic environments like estuaries, where halotolerant microbes thrive in response to variable salinity...
Deep Sea Microbial Ecology
The deep ocean and its underlying sediments represent vast, largely unexplored microbial habitats that extend far beyond the sunlit photic zone. The photic (euphotic) zone typically spans the upper ~100–200 meters of pelagic waters in the open ocean, but its depth varies geographically and seasonally, where sufficient light supports photosynthetic life. Below this lies the deep sea, spanning roughly 1000–6000 meters (bathypelagic to abyssal zones), with deeper hadal trenches extending beyond...
Microbial Bioremediation of Hydrocarbons
Bioremediation is an environmentally sustainable process that employs living organisms—primarily microorganisms—to degrade or neutralize pollutants from contaminated environments. In oil spills and hydrocarbon pollution, bioremediation involves the use of hydrocarbon-degrading bacteria to transform toxic compounds into less harmful substances. This approach leverages natural microbial metabolic processes and is considered both cost-effective and ecologically favorable compared to physical or...
Microbial Bioremediation of Pesticides
Pesticides often feature structurally complex chemical architectures, incorporating halogen groups and multiple aromatic rings. These characteristics confer high chemical stability, rendering many pesticides resistant to natural degradation processes. This resistance poses significant environmental concerns, as persistent pesticide residues can accumulate in ecosystems and affect non-target organisms.Despite the inherent stability of many pesticides, certain microorganisms possess the metabolic...
Microbial Corrosion
Microbiologically Influenced Corrosion (MIC) is a significant form of material degradation caused by the metabolic activities of microorganisms. This phenomenon poses substantial challenges across various industries, including oil and gas, maritime, and water treatment sectors.MIC occurs when microorganisms, such as bacteria, archaea, and fungi, colonize metal surfaces, forming biofilms that alter the local electrochemical environment. These biofilms can lead to the production of corrosive...
