Genetically Modified Organisms

Do your materials contain GMOs?

No. Our Microsilk® fibers do not contain any genetically modified organisms. The process we use to make our fibers does utilize genetically modified yeast. After fermentation is complete, the silk protein is separated from the yeast, and then the remaining yeast cells are destroyed by heat. There are no GMOs present in the final material. This is the same technology that has been used for decades to safely produce cheese, along with insulin and many vaccines.

The sugar that we are using in the fermentation process comes from genetically modified corn. At this time, all large fermentation facilities in the US use sugar from GMO corn because of the abundant supply. It is is widely believed that large-scale fermentation will be possible with non-food crops knowns as cellulosic feedstocks in the future. We are committed to being part of developing the solutions that will enable that future to be realized.
