For the past year, I've been teaching and experimenting with culturing Lactobacillus Reuteri in milk to create a yogurt-like L. Reuteri ferment for health and healing.
Now we're ready to find out:
- Is L. Reuteri in the final product?
- How many CFUs are in there?
- Are there other microbes present?
To answer these questions rigorously, I am launching a community-funded laboratory analysis in collaboration with Eurofins , a professional microbiology laboratory.
This project will generate real, third-party data on a homemade probiotic yogurt. This is rarely done in public, educational settings, but will shed new light on mixing time-tested traditional fermentation techniques with modern probiotics.
WHAT WILL BE TESTED?
A. Bacterial Identification (NGS-PCR)
- Detection and identification of the dominant bacterial species
- Confirmation of the presence of Lactobacillus reuteri
B. Lactobacillus reuteri CFU Count
- Quantification of viable L. reuteri (CFU per gram)
- This directly answers how much L. reuteri is present in the yogurt
C. Total Probiotic CFU Count
- Measurement of all probiotic bacteria combined
- Provides context for how dominant L. reuteri is within the overall microbial population
Objective:
To quantify and characterize the microbial composition of a home-cultured Lactobacillus Reuteri yogurt using professional laboratory methods.
FUNDS RAISED COVER LAB AND PROJECT MANAGEMENT FEES.
This includes lab tests, shipping, and Matthew managing the project (which will include future projects too!)
*** PSA: The 'GoFundMe Tip' is optional and you can modify the amount you wish to donate either up or down. This pays for the GoFundMe platform and does not contribute to this project.
What Supporters Will Receive
Public (Free)

Timeline
This project will begin once the funding goal is reached.
Laboratory timelines may vary, but updates will be shared regularly as samples are prepared, shipped, analyzed, and interpreted.
Stretch Goals (If Funding Exceeds the Goal)
Potential extensions include:
- A second batch for reproducibility
- Additional fermentation substrates or formats (Carrot & blueberry juice)
- These are optional extensions and will only be pursued if feasible.
THANK YOU!
This project exists because of community interest who want to see the real research.
By funding it, you are directly supporting transparent, independent, science-based education.
You can find Matthew on his website Cress Dietetics and on his YouTube channel where he focuses on nutrition and fermentation science.
