Bacterial Protein W90
Bacterial Protein W90 for animal feed, supplied from audited Chinese mills with a full specification and certificate of analysis on enquiry.
About this ingredient
A bacterial single cell protein produced by fermentation and dried to a high protein powder. Its appeal is a protein supply that is independent of harvest and of marine catch, with a consistent profile batch to batch.
Nucleic acid content is the reason inclusion is normally capped rather than open ended, particularly in monogastrics. As with all single cell proteins, confirm the substrate and the organism, since both affect how the product is regulated in your destination market.
Where it is used
- Aqua feed, as a marine protein alternative
- Young animal diets
- Pet food
- Controlled inclusion in poultry and swine
Formulation note
Keep inclusion capped until you have your own performance data, and formulate on digestible amino acids. The consistency of fermentation protein between batches is its main advantage over marine proteins, so ask for several recent certificates to check that.

Frequently asked questions
How is Bacterial Protein W90 made?
Bacteria are grown by fermentation on a controlled substrate, then the cell mass is separated and dried into a high protein powder. W90 is a producer grade code.
Why is inclusion of bacterial protein usually limited?
Bacterial cells are rich in nucleic acids, which contribute nitrogen that is not true protein. That is the main reason inclusion is capped, particularly in monogastric diets.
What should I check before importing it?
Confirm the production organism and substrate, the regulatory status in your country, and the certificate of analysis for protein, moisture and ash.
