  • Did you know2023

    CJ BIO produces the world's #1 tryptophan supply for swine and poultry feed — the same essential amino acid that is also the biochemical precursor to serotonin, melatonin, and niacin in human physiology. The same fermentation tanks that produce CJ BIO's feed-grade tryptophan (for piglet starter diets) also supply pharmaceutical-grade tryptophan used in clinical nutrition (TPN bags for hospital patients) and over-the-counter sleep/mood supplements (5-HTP, L-tryptophan). In 1989, contaminated tryptophan from Japanese producer Showa Denko caused 37 deaths and 1,500 permanent disabilities from eosinophilia-myalgia syndrome — one of the worst pharmaceutical/supplement disasters in US history. The Showa Denko incident was caused by impurities in fermentation-produced tryptophan and triggered immediate FDA bans on tryptophan supplements. CJ BIO is now the dominant global tryptophan producer across all three markets — animal feed, dietary supplements, and clinical nutrition — from a single fermentation platform.

  • Origin2023

    CJ BIO is the biotechnology division of CJ CheilJedang, which itself descends from Samsung's food and chemical businesses. CJ Group was formed in 1953 when Samsung founder Lee Byung-chul established Cheil Industries (CheilJedang means 'First Sugar') to produce sugar and flour — staple food processing. CJ CheilJedang developed amino acid fermentation in the 1980s-1990s, following the Ajinomoto/Kyowa Hakko model, developing proprietary Corynebacterium glutamicum strains for high-yield lysine fermentation. CJ BIO is now the world's largest single lysine producer and #1 tryptophan producer globally — products with no overlap in the Korean chaebols' traditional industries (sugar, food) but built on the same fermentation microbiology platform. The expansion from sugar fermentation to amino acid biotech represents a 70-year industrial evolution of the same Korean company.

  • Capacity2023

    CJ BIO operates one of the world's most geographically diversified amino acid fermentation networks: 7+ plants across South Korea, China (2 plants), USA (Iowa), Indonesia, Thailand, and Malaysia. This geographic spread was strategically built to supply major poultry/swine production regions locally: the Iowa plant serves US Corn Belt integrators; the Chinese plants serve Chinese pork production; Southeast Asian plants serve rapidly growing shrimp and aquaculture sectors. CJ BIO's global fermentation network is sized at roughly 500,000-700,000 MT/year lysine equivalent. The geographic diversification also provides resilience: unlike Evonik's methionine concentration in Singapore, CJ BIO's distributed model means no single country or region controls CJ lysine supply — though Korea (HQ) and China (large share) together represent significant geopolitical exposure.
