Silver labeling of the reducing ends of bacterial cellulose. Carbohydrate
This paper lays to rest for the first time
by independent proof that the reducing ends in a single microfibril
are all located only at one end. This is based on the staining
reaction using silver proteinate. If the glucan chains were anti-parallel,
the labeling of silver would have been on both ends of the microfibril;
however, this was not the case. This has turned out to be an extremely
important proof for cellulose biosynthesis where the site of origin
comes from an organized terminal synthesizing complex (=TC).
