Fermentation processes and strains
Processes are matched to strain metabolism for high acid-production and conversion rates. Production strains are developed for amino-acid processes.
Amino-Acid Fermentation
Fermentation technology
Process development from strain development and seed cultivation to production fermentation, matched to strain metabolism.
Strain → FermentationBreeding, seed culture and production
Product overview
- The scope also includes fermentation products such as citric acid and malic acid.
- Supporting systems include concentrated glucose, medium preparation, compressed air, liquid ammonia and feeding.
The amino-acid industry faces intense competition and higher entry barriers, with innovation, new technologies and processes, environmental protection, and energy/emission reduction as development priorities for feed amino acids. Products include 98, 80 and 70 lysine grades, lysine sulfate, threonine and specialty amino acids.
Lysine cultivation and fermentation are shown as an example. Other products require strain- and process-specific design.
Figures & advantages
Innovative product finishing
Short process routes and reduced investment, targeting high capacity and yield while reducing water, electricity and steam consumption.
DCS automation and quality control
Centralized DCS control integrates processes and automation, reducing manual intervention and labor requirements while supporting stable production and quality control.
Comprehensive technical service
Senior engineers carry out installation, commissioning, production training and management support. Within applicable national standards, the service aims for an improved plant environment, user-friendly operation and achievement of design capacity and performance.
