Benefits of XOS in Miscanthus


(XOS) Xylooligosaccharides are present in Miscanthus and the benefits of XOS in Miscanthus include keeping the colon healthy in humans. Sice XOS are present in Miscanthus, the question becomes whether it does the same thing as other XOS sources already available.

Did you know that roughly 78% of the people that died of Covid were obese and 40% had diabetes? Did you know that 42% of Americans are obese, 11% have diabetes and 25% of Americans 18+ are prediabetics? These numbers to me are staggering and sad. While there is no magic bullet that will fix these problems, did you also know that something as small as an alteration in the intestinal ecosystem is linked to irritable bowel syndrome, type 2 diabetes, and obesity? (1,2) With around 100 trillion microorganisms in the human GI and the majority of them being anaerobic bacterial species in the colon, it is crucial that these organisms are taken care of to help prevent disease and in turn keep us healthier and protect us from things like Covid.

So how do we take care of these organisms in the Colon? One way is Xylooligosaccharides or XOS. The XOS help microbiota like Lactobacillus and Bifidobacterium species, which are very good fermenters in the intestinal system, to thrive. (2) A study showed that the incorporation of XOS in the food product mediated the changes in bacterial growth (3) and as mentioned above, the alterations in the microbiota are what can lead to disease.

The benefits of XOS in Miscanthus

What does this have to do with Miscanthus? Miscanthus has roughly 13.5% XOS prebiotic naturally occurring in the plant. (5) This is great because miscanthus is all-natural, abundantly grown, and a very sustainable crop. Since XOS is present in Miscanthus, the question becomes whether it does the same thing as other XOS sources already available. There was a study, “In Vitro Fermentation of Xylooligosaccharides Produced from Miscanthus x giganteus by Human Fecal Microbiota”(4) that looked at how well Miscanthus XOS compared to chemically made XOS and pectin. The positive results showed that the beneficial bacteria, Bifidobacterium and Lactobacillus increased during fermentation when Miscanthus XOS was given to them. Is Miscanthus XOS the answer to solving all of the disease problems plaguing our society? Probably not, however, understanding how XOS from Miscanthus can help keep the colon healthy in humans is a start. Oh, and did I mention Miscanthus is already doing just that in pets?

Eric Allphin, V.P. Business Development
Eric Allphin is a native to Southwest Missouri. He was born in Joplin, Missouri and grew up near Granby, Missouri on a small hobby beef farm. After graduating high school at East Newton, Eric served a two-year mission in Costa Rica for his church. Upon returning home, he received his Associates Degree at Crowder College and transferred to University of Missouri where he graduated in December 2009 with his Bachelor of Science in animal science. After completion of his bachelorís, Eric decided to further expand his knowledge into agriculture as he felt both degrees would complement each other. Eric received and assistantship with the University of Missouri and worked closely with USDA-ARS. His research was focused around how crop performance changed depending upon the landscape in which that crop was planted. So how corn, soybeans and also perennial grasses like switchgrass or Miscanthus would perform on different topsoil depths. His research was very conclusive, and Eric graduated with his Master of Science in crop, soil and pest management in December 2011. After owning an ag consulting business for a few years, Eric accepted the position of Director of Agriculture/Agronomist for Renew Biomass. Eric focuses his efforts toward the agricultural side of our business; managing the production of Miscanthus on over 5,000 acres. Most importantly, Eric has been married to his beautiful wife, Rachel, for 10 years. They have 3 children: Maveric, Wyatt and Emery.
