Abstract
Cellulosomes are intricate molecular machines that efficiently degrade lignocellulose. Previous studies have proposed that cellulosomes are mainly produced by microorganisms from the soil environment and from the rumen environment of ruminants, and are therefore related to the carbon cycle in nature, the feeding efficiency of livestock, and the emission of the greenhouse gas methane. A recent study showed that cellulosome-producing strains of the genus Ruminococcus also exist in the human gut, and that their prevalence is closely related to the dietary habits of the host, thus having potential relevance and impact on human nutrition and health. Research on cellulosomes may thus significantly contribute to the fields of environmental sustainability, livestock agriculture, and human nutritive health.
