Microbiota biobanking using ice recrystalization inhibitor

This study use different ice recrystalization inhibitors (IRIs) for better storing live microbiota. We evaluated whether the addition of IRIs can improve the cultivibility of microbiome and maintain their resposnes to prebiotic kestose. Frozen or fresh microbiota were cultured with or without kestose for 24 hours, and microbiota samples were collected for metaproteomics analysis.
