“…1). The direction of maximum growth is actually helical (see Green 1954;Probine andPreston 1961, 1962;Probine 1963). This report will focus attention on the gross aspects of elongation (changes in cell length and diameter only).…”

“…The brightness at the cell centre (a) is due to a transverse but scattered arrangement of cellulose. The brightness at the margin (cylindrical region) is due to the fact that the polarized light encounters the wall at an oblique angle and interacts with its texture "end-on" (see Frey-Wyssling 1959). The margin is thus positively birefringent, the central region negatively birefringent, both with respect to the cell axis.…”

SummaryMany oriented growth phenomena, including the elongation of the Nitella internode, are based upon oriented or textured cell wall structure. In many cases the ordered textures are not present in the earliest stages of cell development but appear later. In Nitella lateral cell (leaf) development the first appearance of transverse wall texture (detected in polarized light) approximately coincides with a transverse stretching of the cell and its wall. This oriented stretching appears not to have its origin in a pre-existing texture but rather to be the result of a particular distribution of wall expansion rates. The relation between rates and oriented distortions is studied as a general phenomenon. The form these rate variations must take to provide longitudinal, transverse, or isotropic distortion is derived. Model devices made of rubber membranes, where expansion rate is varied by reinforcement of the rubber, generate distortions (textures in the rubber) of the type predicted. In the course of development it is possible that imbalances in expansion rate based on gradients (of metabolites, pH, light, etc.) bring on, through strain orientation, the initial alignment of originally randomly oriented fibrous ultrastructures, such as microfibrils of the cell wall or cytoplasmic microtubules.

The Effect of Subtrate Availability on Cellulolytic Enzyme Production by Selected Wood-Rotting Microorganisms

Extracellular cellulases have been produced in shake cultures of Polystictus ver8icolor, Fornes anno8U8, Lenzites trabea, Poria monticola, and Bacillus polymyxa, using substrates of cellulose powder and river birch woodmeal. The comparative effect on enzyme production of wet and dry ball milling of the substrates has been examined. Studies were also made to establish the relative amounts of enzyme diffused, bound, or adsorbed during production and the influence of pH on cellulase activity. It was found that wet ball milling reduces the particle size of both materials more rapidly than dry ball milling. There was an overall increase in enzyme released as the particle size of the substrate decreased, but no correlation was established between this phenomenon and growth of the microorganisms. Dry milled substrates of comparable particle size produced higher yields of cellulases than the wet milled substrates, Lenzites trabea being more active in enzyme production than any of the other organisms. Diffusion of cellulases occurred more readily in the brown rot fungi than in the two white rot microorganisms and a higher percentage of enzyme remained bound with the latter group.
