lignocellulose-degradation
Lignocellulose degradation refers to the enzymatic and microbial breakdown of the complex plant cell wall matrix composed of cellulose, hemicellulose, and lignin. Because this structural material makes up the bulk of terrestrial plant biomass, understanding how it can be efficiently broken down is essential for studies of carbon cycling, decomposition, and plant biomass conversion into usable sugars. Research in this area helps reveal how plants build resilient cell walls while also informing strategies to unlock their stored energy for biofuel and industrial applications.

An endangered Chinese red deer subspecies has gut bacteria that are unusually good at breaking down tough, fibrous reed grass, and scientists found the specific microbes and enzymes responsible. The discovery could eventually help turn woody plant waste into usable products.
Tarim red deer (TH) showed higher fecal microbial diversity and greater abundance of fiber-degrading bacteria (Ruminococcaceae, Lachnospiraceae, Alistipes) than the related Tianshan red deer (TS).
TH fecal samples had higher cellulase and hemicellulase activity and degraded reed straw faster in lab (in vitro) tests than TS samples.
Transplanting TH gut microbiota into antibiotic-treated mice on a reed-containing diet altered the mice's fiber-related gut bacteria, metabolites, body weight, and intestinal structure.
