Method of inhibiting microbial activity using insoluble dialdehyde polysaccharides

摘要

Microbial growth is inhibited in a medium susceptible to such growth by treatment with an effective amount of an insoluble dialdehyde polysaccharide which is sufficient to maintain an insoluble aldehyde content in the medium of at least about 0.1 weight percent. The insoluble dialdehyde polysaccharide does not exert a systematic effect on the medium. Suitable dialdehyde polysaccharides for this purpose are insoluble dialdehyde starch, dialdehyde cellulose, and the like.
