Also, the stabilities could be related to the viscosities and the extents of adsorption. These authors have also shown that the relationship between MW and biodegradation is not straightforward. The first polymer segments to contact the clays would orientate flat on the sorbent. , 1981), and these loops would not be protected from microbial attack if microorganisms or the enzymes they secrete gain access to the loops. To stabilize preformed aggregates, the polysaccharide would need to diffuse to the adsorption site in the internal surfaces.
Chapters by Hayes and Swift (1978), Cheshire and Hayes (1990), and Clapp et al. (2005) have reviewed relevant aspects of the chemistry and compositions of polysaccharides and have discussed the reactivities of saccharides in the soil environment. Interest in soil saccharides, and especially in soil polysaccharides, is relatively recent, and their studies may be considered to be in the modern era of soil organic matter research. Martin (1945, 1946) established that the “slimy” bacterial products 22 EVOLUTION OF CONCEPTS shown by Waksman and Martin (1939) to aggregate sand–clay mixtures were polysaccharides.
2005). Sodium hydroxide is probably the best of the aqueous solvents used. Its efficiency might well be related to charges, arising predominantly from uronic acids. These are characteristic of many soil polysaccharides, though sulfonated polysaccharides (typically with SO3H functionalities on C-6 of the hexose sugars) may also contribute to charge. Some of the dipolar aprotic solvents, especially DMSO, can be expected to be good solvents for soil saccharides. DMSO has the ability to break hydrogen bonds and can even dissolve cellulose.
