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. The amount of colour change can be compared with the included chart to help determine the level of contamination. 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 comes in a pack size of 10 slides / tests per box.

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

How to Use

1. Add 2ml of the test sample to the tube. To aid the user, 2ml of test sample can be determined by adding the sample up to the moulded line in the tube.
2. Incubate the SRB test / dipslide at 30 degrees C for up to 6 days. Check the test daily for the first three days.
3. If there is no colour change after 6 days, this indicates a negative result.
