Hyaluronic acid

Safety, purity and consistency all in one raw material


Current commercial sources of hyaluronic acid (HA) are derived from either rooster combs or various attenuated strains of Streptococcus. Due to the risk of animal-derived contamination of the final product, the use of HA produced by rooster comb extraction is decreasing in the industry.

Streptococci are inherently pathogenic to human beings due to their secretion of toxins and resulting hemolytic properties. In addition, both production methods employ large volumes of organic solvents in different steps of the process, which can lead to impurities in the final HA ingredient.

What is Bacillus-derived hyaluronic acid?

Novozymes has developed the next-generation HA, the world’s first and only recombinant source of HA based on the fermentation of Bacillus subtilis, in a Q7 validated cGMP process.

Working with raw materials that are already Q7 compliant can help medical device and pharmaceutical drug manufacturers reduce testing time, save on manufacturing costs and take products to market faster.
