Can Cows Consume Cellulose? Animals such as cows have anaerobic bacteria in their digestive tracts which digest cellulose. Cows are ruminants, or animals that chew their cud. Ruminants have several stomachs that break down plant materials with the help of enzymes and bacteria.
Do cows eat cellulose? As a cow grazes, she is primarily consuming cellulose, the building block of plant matter that is difficult to digest.
Can cows digest cellulose or chitin? Animals such as termites and herbivores such as cows, koalas and horses all digest cellulose, but even these animals do not themselves have an enzyme that digests this material.
What does cellulose do for cows? Undigestible cellulose is the fiber which aids in the smooth working of the intestinal tract. Animals such as cows, horses, sheep, goats, and termites have symbiotic bacteria in the intestinal tract. These symbiotic bacteria possess the necessary enzymes to digest cellulose in the GI tract.
Humans cannot digest cellulose in their food like cattle due to the absence of rumen. The cellulose of the food is digested by the action of bacteria present in rumen.
In the human body, cellulose cannot be digested due to a lack of appropriate enzymes to break the beta acetal linkages. The human body does not have the digestive mechanism to break the monosaccharide bonds of cellulose.
Ruminants have multi-chambered stomachs, and food particles must be made small enough to pass through the reticulum chamber into the rumen chamber. Inside the rumen, special bacteria and protozoa secrete the necessary enzymes to break down the various forms of cellulose for digestion and absorption.
Humans cannot digest cellulose because they lack the enzymes essential for breaking the beta-acetyl linkages. The undigested cellulose acts as fibre that aids in the functioning of the intestinal tract.
Cellulases break down the cellulose molecule into monosaccharides (“simple sugars”) such as beta-glucose, or shorter polysaccharides and oligosaccharides.
After years of independent mutations, these mammals have developed a lysozyme enzyme with similar properties to the ones found in ruminants. Therefore, they are able to break down cellulose and benefit from the resulting nutrients.

Cellulose is very hard to digest, so the cow relies on bacteria and other organisms that live inside them to break down the cellulose into a form from which they can extract nutrients. The ruminant stomach is vastly different from your own digestive system. Without cellulose-digesting bacteria, cows wouldn’t be.
The answer is, because of the Rumen. The Rumen allows cow’s and many other large herbivores to live off a grass and plant only diet and still be able to survive, very easily. The microbes feed off the food while fermenting it for the cow to digest it. Both are getting good benefits!
->Ruminants have a large sac like structure between the small intestine and large intestine. The cellulose of the food is digested here by action of some bacteria which are absent in humans. ->Animals such as cows have anaerobic bacteria in their digestive tract which digest cellulose.
Cellulose is a polysaccharide composed of a linear chain of β-1,4 linked d-glucose units with a degree of polymerization ranged from several hundreds to over ten thousands, which is the most abundant organic polymer on the earth.
Sheep belong to the ruminant classification of animals. Ruminants are characterized by their four-chambered stomach and “cud-chewing” behavior.
It’s called cellulose, and you’ve eaten it before. A lot.
First the good: Eating cellulose won’t kill you. There are no known harmful side effects from adding it to food, and it’s completely legal.
Green beans were highest in cellulose and hemicellulose; potatoes highest in lignin; and carrots highest in pectin. On a wet-weight basis, fresh apples and peaches, fresh-cooked green beans, canned carrots, and canned and frozen potatoes were higher in DF and NDF than other forms of the fruit or vegetable.
Cellulose is the main substance in the walls of plant cells, helping plants to remain stiff and upright. Humans cannot digest cellulose, but it is important in the diet as fibre. Fibre assists your digestive system – keeping food moving through the gut and pushing waste out of the body.
For humans, cellulose is indigestible, and the majority of gut bacteria lack the enzymes required to break down cellulose.
Ruminant Digestion. Like other vertebrates, ruminant Artiodactyla (including cattle, deer, and their relatives) are unable to digest plant material directly, because they lack enzymes to break down cellulose in the cell walls. Digestion in ruminants occurs sequentially in a four-chambered stomach.
One particularly important bacterial genus that takes part in the degradation of cellulose is gram positive Ruminococcus (Figure 1). Ruminococcus bacteria break down the plant fiber into the monosaccharide glucose, which can then be further broken down through glycolysis.
The most important difference in the way the two polymers behave is this: You can eat starch, but you can’t digest cellulose. Your body contains enzymes that break starch down into glucose to fuel your body. But we humans don’t have enzymes that can break down cellulose. Cellulose is also a lot stronger than starch.
Biomass-degrading microorganisms use lytic polysaccharide monooxygenase (LPMO) enzymes to help digest cellulose, chitin, and starch. By cleaving otherwise inaccessible crystalline cellulose chains, these enzymes provide access to hydrolytic enzymes.
Although multiple bacteria inhabit the cow’s rumen, this lesson focuses on two harmless microbes, Ruminococcus and Selenomonas, which break down cellulose and starch in plant matter, respectively. These bacteria obtain nutrients from the cow’s diet, and the cow gains energy from the products of bacterial metabolism.
