Hello everyone,

My lab plans to use Phospholipid Fatty Acid Stable Isotope Probing (PLFA-SIP) to see if a specific microbe utilises a certain substrate as a carbon source. Luckily our microbe has a unique lipid molecule only found within its group.

However, we are trying to figure out what analytical machine will be best for our purposes. I have found in some literature using gas chromatography/isotope ratio mass spectrometry (GC-c-IRMS). Therefore, would this be suitable for detecting potential isotope uptake in our microbe?

Thank you very much
