Sulfate reducing bacteria (SRB) is a bacteria that can obtain energy by oxidizing organic compounds / molecular hydrogen and reducing sulfate to hydrogen sulfide. In essence, this bacteria 'breathes' sulfate. The SRB test is a small vial containing a culture gel that turns black if sulfates are present in the test sample. Sulfates are produced when sulfates are reduced by bacteria. Sulfate reducing bacteria are anaerobic organisms that cause corrosion and spoilage in multiple industries. The bacteria can cause particular damage to oil pipelines and metal parts. The SRB test kit contains 20 x 10 ml tubes.

SRB

• Survives in oxygen depleted / oxygen free environments
• Corrodes at a very fast rate
• Reduces sulfates and creates hydrogen sulfide
• Resultant hydrogen sulfide gives off a foul 'rotten egg' odour
• Other signs of its presence in water are a change in colour (to black)
• Major cause of microbial influenced corrosion

Storage:

• 2-8°C away from light, until the expiry date on the label. 

Shelf Life:

• 2 years

How to Use:

• Inoculate tubes preparing serial dilutions of the initial sample
• Incubate at 25-35°C. Examine tubes daily for the first week and intermittently for up to 30 days.
