  • Cellulolytic, N.sub.2 -fixing bacteria and use thereof
    Patent number: 4973559
    Abstract: Cellulolytic, N.sub.2 -fixing bacteria have been isolated from terrestrial ecosystems. Many of these bacteria can be taxonomically classified as Bacilli, while others may not be characteristic of any previously defined taxon. These organisms are useful for converting lignocellulosic and other cellulosic materials into foods and fertilizers having increased carbohydrate digestibility and enhanced assimilable nitrogen content.

  • Modified plant fiber additive for food formulations
    Patent number: 4774098
    Abstract: Food compositions are prepared incorporating an alkaline peroxide-treated conversion product of a nonwoody, lignocellulosic substrate. In a ruminant system, the conversion product serves as a highly digestible carbohydrate source. When added to foods intended for consumption by humans and monogastric animals, the conversion product functions as a natural source of dietary fiber and a noncaloric substitute for cereal flour or other amylaceous materials. It is also useful as an extender and promoter of functional properties in doughs and batters.
