Sulfur ingredients.
Built with biology.

Sulfur-containing nutrients are an important part of everyday nutrition for people and pets. Almost all of them are made through petrochemical processes that rely on harsh chemistry. We’re here to change that.

See how it works

Natáur’s sulfur biotechnology platform engineers microbes to produce sulfur ingredients through fermentation.

Moving beyond petroleum

Naturally renewable feedstocks

Sourced from resources that regenerate over time.

Petroleum-derived inputs

Sourced from materials derived from fossil resources.

Made with biology

Fermentation uses biological pathways to produce sulfur ingredients.

Multi-step chemical synthesis

Chemical reactions are used to produce the ingredient.

Avoids hazardous intermediates

Bypasses reactive chemicals used in conventional synthesis.

Hazardous intermediates

Reactive materials pose risks to human health and the environment.

Production across regions

Can scale through fermentation facilities in multiple locations.

Regionally concentrated supply

Limited production regions increases disruption risk.

Our bio-based process

Feedstock

It starts with sugar. Not ethylene oxide, not a petrochemical feedstock.
Fermentation

Cells do the synthesis that a chemical reactor used to do.
Purification

Separate and purify.
Product

Chemically identical replacement.

Sulfur platform

Sulfur-containing compounds have historically been difficult to produce biologically. Their biosynthetic pathways are energetically demanding, tightly regulated, and can generate intermediates that are toxic to the cell.

Natáur’s sulfur biotechnology platform addresses these challenges by improving sulfur utilization, reducing cellular stress, and directing more cellular resources toward production of the desired compound.
