Overview
Shewanella putrefaciens is a versatile bacterium primarily recognized for its role in food spoilage, particularly in seafood. It thrives in diverse environments, including marine habitats and soil. The bacterium is facultatively anaerobic, meaning it can survive with or without oxygen. Its ability to reduce metal ions, such as iron and manganese, has made it a subject of interest in bioremediation. This capability allows it to detoxify contaminated environments, making it valuable for environmental cleanup projects.
Key Features
Shewanella putrefaciens exhibits unique metabolic traits, including the reduction of metal ions, which distinguishes it from many other bacteria. It produces hydrogen sulfide, contributing to its spoilage activity in food. The bacterium is also known for its adaptability to extreme environments, such as low-oxygen conditions. Its genetic makeup allows it to switch between aerobic and anaerobic respiration, enhancing its survival in varied habitats.
Application Areas
In bioremediation, Shewanella putrefaciens is used to clean up heavy metal-contaminated sites by reducing toxic metal ions to less harmful forms. Its role in the food industry is less desirable, as it accelerates spoilage in perishable goods like fish. Research laboratories utilize this bacterium to study microbial metal reduction and anaerobic respiration processes. Its applications extend to bioelectrochemical systems, where it aids in energy generation.
Precautions
Handling Shewanella putrefaciens in laboratory settings requires standard microbiological safety practices, including the use of personal protective equipment. Its spoilage potential necessitates strict hygiene in food storage and processing facilities. In environmental applications, ensure compliance with local regulations to prevent unintended ecological impacts. Proper strain selection is critical to avoid introducing harmful variants into sensitive ecosystems.
B2B Procurement Guide
When procuring Shewanella putrefaciens for research or industrial use, verify the strain's specifications to match your project requirements. Reputable suppliers should provide detailed documentation, including strain history and performance data. Storage conditions are crucial; the bacterium should be kept at recommended temperatures to maintain viability. For bioremediation projects, consult experts to determine the most effective strain and application method.
