Lauren Petersen, PhD, is a postdoctoral associate investigating the microbiome and she’s back on the podcast to update us on her research. Be sure to listen to our first interview first! I sent Lauren some of the probiotics we use in our practice, and she said, “they look great!” Lauren did some calculations for the number of CFUs, and she got pretty much exactly what the bottle claims for live organisms, with growth on both Lactobacillus-selective and Bifidobacterium-selective medias. The same was not true for Renew probiotics where her qPCR analysis showed that Bifidobacterium was pretty much all dead. Here are some photos of the Lactobacillus-selective and Bifidobacterium-selective plates that Lauren used to grow the probiotics. She shot for 250 CFUs per plate (based on if all the organisms per gramme probiotic were alive) and that's pretty much what she got!
