Yeast Autolysate & Cell Wall Beta-Glucan Extraction: Technology Transfer for Immune-Active Co-Products

In the biomanufacturing of Organic Zinc-Enriched Yeast and 3,320 PPM Selenium-Enriched Yeast (Saccharomyces cerevisiae), downstream processing yields two distinct high-value bio-active fractions:

1. Intracellular Cytoplasmic Fraction: Rich in organo-mineral complexes (Zinc peptides, Selenomethionine) and soluble B-vitamins.
2. Insoluble Cell Wall Fraction: Rich in Beta-1,3/1,6-Glucan and Mannan-Oligosaccharides (MOS)—two premier immune-modulating co-products widely utilized in functional human foods, clinical nutraceuticals, and veterinary feed premixes.

By mastering dual-stream downstream extraction during Biotechnology Technology Transfer, CDMOs increase total biomass revenue per fermentation run by 25% to 40%.

This engineering article outlines the autolysis kinetics, membrane separation SOPs, and co-product extraction technology transfer package provided by Probiota Innovations.

3. The Co-Product Extraction SOP Transfer Package

CDMOs acquiring Probiota Innovations' yeast bioprocess technology receive complete dual-stream extraction engineering dossiers:

1. Controlled Autolysis SOP: Precise enzyme activation parameters ($52^\circ\text{C} - 55^\circ\text{C}$, pH 5.0–5.4, 16–24 hours) maximizing cellular permeabilization without degrading Selenomethionine.
2. Disk-Stack Separation SOP: High-G continuous centrifugal separation ($7,500 \times g$) isolating light cell wall solids from heavy soluble mineral extract.
3. Alkaline/Acid Purification SOP: Chemical wash SOPs yielding ultra-pure $\ge 80%$ insolubilized Beta-Glucan for pharmaceutical applications.
4. Full IP Sale or Out-Licensing: Flexible commercial deal models.
