β-Carotene (C40H56) is one of the carotenoids, an orange-yellow lipid-soluble compound that is the most common and stable natural pigment in nature.
HSF's Natural Beta-carotene 96% Powder/Crystalloid is a kind of red to brownish-red crystalline powder based on the fermentation of Blakeslea trispora. β-Carotene is widely used in the food, feed, pharmaceutical, and cosmetic industries.
The metabolism of Blakeslea trispora can produce natural beta-carotene powder and lycopene. The performance of this strain has been widely recognized and industrialized. The pigments produced by the fermentation method of Blakeslea trispora have the characteristics of natural products, short cycle, and high yield. It has been technologically advanced and solved the problems of seasonal shortage of raw materials and high cost of pigments obtained by plant extraction methods.

Microbial Strain Development & Smart Fermentation System
1. Strain Screening & Optimization
Built a 3,000+ microbial strain library.
High-throughput screening via microfluidic chips (500 strains/day) identified Blakeslea trispora HSF-Bt07 with 3× higher β-carotene yield than wild strains.
Adaptive evolution (ALE) under stress (high osmotic pressure/low temperature) enhanced stability: 99% yield retention over 20 generations.
2. Light/Oxygen-Sensitive Fermentation System
Double-layer stainless steel bioreactor:
UV-resistant coating + nitrogen blanketing → dissolved oxygen ≤3% (vs. industry average 8%).
3. Dynamic control technology
Embedded sensors collect 12 parameters (pH, temperature, cell density) every 10s.
Machine learning-based feeding adjusts C/N ratio → cell density reaches 65g DCW/L (vs. 40g in traditional processes).
Two-Phase Fermentation:
48h biomass growth phase: 300% biomass increase.
Metabolic burst phase: Gradient temperature triggers β-carotene production at 10g/L.
