Science Project -- Microorganisms and Sodium Nitrate

Post by ejordan25 » Mon Oct 25, 2010 11:01 pm

For my science project we have to ask a professional questions about our science topic, so if anyone has some time to answer these I would be very thankful!

1. Does Sodium nitrate effect bacteria growth?

2. Is sodium nitrate good at inhibiting bacteria growth?

3. Do sodium nitrate and sodium nitrite differ in effecing bacteria growth?

4. What qualifies you to be a professional in this field?

Thank you! Its very appreciated

1. Not directly. It must be converted to nitrite first. And not all bacteria are affected.
2. No. Unless you count that its natural transformation in nitrite makes it effective, because that is exactly why it is used. But once again it will depend on the bacteria.
3. Yes. See above
4. A Ph.D. in microbiology, 6 years of post-doctoral research in environmental bacteriology plus teaching a few courses at university level.
