New Crystallite Orientations of Cellulose I in Spirogyra Cell-walls

Description
Summary:DURING our work on barium sulphate in Spirogyra 1 , clean cell-wall material was prepared, using methods applied earlier in isolations of cell-walls of fungi 2 . This induced us to pay some attention to certain problems concerning Spirogyra cell-walls. In the native state, these do not stain with chlor-zinc iodide, although Frey 3 definitely claims the presence of cellulose. Nicolai and Preston, discussing their X-ray examination of a great number of filamentous green algae 4 , conclude that in very few families can it be claimed with certainty that the wall contains any cellulose common to higher plants, and that it is striking that such a well-known and often investigated genus as Spirogyra is still in doubt.
