lignocelluloses

In the meantime, it would be wise for developing country governments and technical assistance agencies to anticipate the development of cheap and practical saccharification, and perhaps direct fermentation, of lignocelluloses to ethanol.

We have shown that the hydroxyfurfurals are constituents of the lignocelluloses.

Consequently there is for each a special method of attack, and it is a reversion to pure empiricism to expect any one treatment to act equally on the pectocelluloses, lignocelluloses, and cutocelluloses.

We must note, however, that the celluloses of the lignocelluloses are obtained as residues of various reactions, and are not homogeneous.

Of importance also is the identification of the hydroxyfurfurals as constituents of the lignocelluloses generally, and the proof that the characteristic colour-reactions with phenols (phloroglucinol) may be ascribed to the presence of these compounds (p. 116).

The ordinary lignocelluloses are stained a purple brown changed to brown on washing.

The former are constituents of celluloses, the latter of the lignone complex of the lignocelluloses.

This, however, is not difficult, and we need only call to mind that the lignocelluloses are characterised by the presence of methoxy groups and a residue which is directly and easily hydrolysed to acetic acid.

The 'pectic' group consequently must be extended to include hydrated and soluble forms of the mixed complex of condensed and unsaturated groups with normal carbohydrates, such as constitute the fibrous lignocelluloses.

In 'nitrating' the lignocelluloses this phenomenon of internal condensation is much more pronounced (see p. 131).
