1159 results about "Snail" patented technology

A snail is, in loose terms, a shelled gastropod. The name is most often applied to land snails, terrestrial pulmonate gastropod molluscs. However, the common name snail is also used for most of the members of the molluscan class Gastropoda that have a coiled shell that is large enough for the animal to retract completely into. When the word "snail" is used in this most general sense, it includes not just land snails but also numerous species of sea snails and freshwater snails. Gastropods that naturally lack a shell, or have only an internal shell, are mostly called slugs, and land snails that have only a very small shell (that they cannot retract into) are often called semi-slugs.

Enhancement of accessibility of cellulose by expansins

Plant cell expansion is regulated by wall relaxation and yielding, which is thought to be catalyzed by elusive "wall loosening" enzymes. By employing a reconstitution approach, we initially found that a crude protein extract from the cell walls of growing cucumber seedlings possessed the ability to induce the extension of isolated cell walls. This activity was restricted to the growing region of the stem and could induce the extension of isolated cell walls from various dicots and monocots, but was less effective on grass coleoptile walls. Sequential HPLC fractionation of the active wall extract revealed two proteins with molecular masses of 29 and 30 kD, as measured by SDS-PAGE, associated with such activity. Each protein, by itself, could induce wall extension without detectable hydrolytic breakdown of the wall. We proposed the name "expansins" for this class of proteins. Expansins have been isolated from various plant sources including oat, cucumber, broccoli, celery, tomato, cotton, cabbage, and corn, and also from snail and its feces. These proteins weaken the intermolecular bonds between plant wall polysaccharides. They decrease the mechanical strength of commercial products made from polysaccharides, such as paper, and therefore present a novel approach in developing new technologies in industries which make use of such polysaccharides, such as in the paper industry, in the applications of polysaccharide gums and related products. These proteins moreover present a novel approach in the control of plant growth.
