Space Yeast Raw Material Introduction
Space Flight (Real Space Mission)
Original Strain Selection: Carefully chosen from a resource bank of high-performance, high-potential application strains. Spacecraft: Carried aboard the Shenzhou-11 spacecraft and the Tiangong-2 space laboratory. Orbital Parameters: Flight altitude: 393 km; In-orbit flight duration: 31 days for lactic acid bacteria, 63 days for yeast. Space Environment: Subjected to extreme conditions unreplicable on Earth—such as microgravity, intense cosmic radiation, high vacuum, extreme temperature variations, and weak magnetic fields—forcibly inducing endogenous gene mutations in the strains.
Ground Super-Screening (Core Technology)
After returning to Earth, the R&D team employed the following methods to screen from hundreds of billions of mutant strains: High-throughput screening and in vitro functional screening models. Targeted screening for acid tolerance, bile salt tolerance, intestinal colonization capacity, antioxidant, anti-inflammatory, and metabolic regulation properties. Result: Four "space-grade superpower" strains with Chinese invention patents were ultimately selected:
SS18-119 (Space Lactiplantibacillus plantarum)
SS18-5 (Space Lactiplantibacillus plantarum)
9-35 (Space Limosilactobacillus reuteriFullarton-9-35)
ST26-13 (Space-Mutated Saccharomyces cerevisiae)
Summary of Technological Strength
One of the very few enterprises in China possessing independent intellectual property rights in both the "Space Probiotics" and "Space Brewer's Yeast" sectors. Holds 22 Chinese National Invention Patents + 1 PCT International Patent. Maintains a library of over 7,000 space-mutated microbial strains. Research outcomes have been incorporated into standard Chinese university textbooks. Recognized as a benchmark enterprise for the commercialization of aerospace technology.
R&D Background
The Fullarton Space-Grade Probiotics and Space Yeast raw material series are the outcomes of a national-level space microbial breeding project under China's manned space program. This achievement stems from the collaboration between Fullarton Bioengineering Technology (Beijing) Co., Ltd., a Chinese high-tech enterprise, and leading research institutions including the College of Food Science and Engineering of Jilin University, the Institute of Microbiology of the Chinese Academy of Sciences, the China National Research Institute of Food and Fermentation Industries, and the University of Adelaide.
