Continuous Fermentation


Fermentation is a process where microorganisms are grown under controlled conditions with an aim of optimizing the growth of the organism for production of a target microbial product.

Continuous Fermentation involves the development of microorganisms under a controlled environment where culture media are constantly eliminated and replaced in a bioreactor for the manufacturing of the desired bioproduct.

Esco Aster provides fermentation capabilities from Diagnostic Antigen / Antibodies, Peptides, Intermediates (Viral Vectors), Therapeutics, to Food Ingredients / Products for Cellular Agriculture / Alternative Proteins in both continuous liquid and solid-state fermentation.


Strain Development

Large-scale Contract Fermentation (5-100L)

Fermentation can then be scaled up to 50-100 (50,000-100,000 liters) tons in a purpose built dedicated site with our Design, Build and Operate contract services
