Product Description

The Sulfate Reducing Bacteria (SRB) Test Tube is a diagnostic tool used to detect the presence of SRB in water, industrial fluids, and oilfield samples. It helps assess microbial contamination by identifying hydrogen sulfide-producing bacteria, which cause corrosion, biofouling, and water quality issues. Ideal for laboratories, wastewater treatment, and industrial monitoring.

Applications of Sulfate-Reducing Bacteria (SRB)

1 .Wastewater Treatment

• SRB can reduce heavy metals, pathogens, and COD in wastewater
• SRB can be used to pre-treat anaerobic digestion
• SRB can be used to treat domestic wastewater

2. Bioremediation – SRB help remove heavy metals and sulfate pollution from wastewater, making them useful in environmental cleanup.

3. Microbial Corrosion – While often problematic, SRB are studied in industrial corrosion processes to develop protective measures for pipelines and infrastructure.

4. Oil and Gas Industry – SRB play a role in reservoir souring and biofouling, but they are also used in microbial enhanced oil recovery (MEOR).

5. Bioleaching – Used in mining to extract metals from ores by reducing metal sulfates.

What is a Bacterial test tube?

A bacterial test tube is a cylindrical glass or plastic tube used in microbiology labs to grow, cultivate, and analyze bacteria. It typically contains a suitable growth medium, such as agar or broth, that provides nutrients for bacterial colonies to develop under controlled conditions. These tubes are essential for scientific research, medical diagnostics, and environmental testing, helping scientists study bacterial behavior, identify species, and test antimicrobial agents.

What Are Sulfate-Reducing Bacteria?

Sulfate-Reducing Bacteria (SRB) are anaerobic microorganisms that convert sulfate (SO₄²⁻) into hydrogen sulfide (H₂S) through a metabolic process known as sulfate reduction. These bacteria thrive in oxygen-deprived environments such as deep-sea sediments, wetlands, water treatment systems, and oil and gas pipelines. While SRBs play a vital role in the natural sulfur cycle and biogeochemical processes, they can also contribute to industrial challenges like metal corrosion, biofouling, and souring in petroleum reservoirs.

How does an SRB test tube work?

he test tube contains a specific medium that supports the growth of SRB. When SRB metabolize sulfate, they produce hydrogen sulfide gas, which reacts with the medium to create a visible change, such as a black precipitate or gas bubbles. This reaction confirms the presence of SRB.

Is Sulfate-Reducing Bacteria Harmful?

Sulfate-reducing bacteria (SRB) can be harmful in certain environments. They produce hydrogen sulfide (H₂S), a toxic gas that causes corrosion in pipelines, foul odors, and contamination in water systems. In high concentrations, H₂S can pose health risks such as respiratory issues, nausea, and eye irritation. Proper monitoring and control are essential.
