Is there someone who can help for the protocol and related article about using GCMS to determine the metabolite profiling in Lactobacillus plantarum which is fermented in milk?
I think the protocols found in these articles (attached) may actually help you, since researchers are using GC-MS approach for the characterization of Lactobacillus and other microbial strains in dairy products.
