Examples
-
This is obviously due to the conservation of 'hemicellulose' products, which are hydrolysed and dissolved in the treatments for 'crude fibre' estimation.

The leaves and stems, with their tough cell walls made of cellulose, hemicellulose and lignin, are more of a nuisance than anything else.

The researchers modified the E. coli genome, inserting genetic code for the production of an enzyme called hemicellulase, which can break down hemicellulose into smaller sugar molecules which E. coli can then turn into fatty acids.

Wood has evolved to keep its sugars to itself, covering them with lignin — a substance that gives cell walls rigidity — and then locking them in a matrix of cellulose and hemicellulose protected by complex chemical bonds.

The energy is bound up in the cellulose (especially the hemicellulose), which has to be freed from the inert lignin and then converted into sugars (a process called, naturally enough, saccharification), which can then be fermented into ethanol.

This reduces the sizes of solid particles, changes the consistency from a damp fiber to sludge, and most importantly breaks down the walls of the plant cells, allowing hemicellulose to escape into the syrupy mixture.
