Abstract: A saccharide composition comprising maltooligosyl derivatives of turanose and palatinose which can be readily produced, separated, and purified in a relatively-high yield from maltooligosylsucrose by allowing non-reducing saccharide-forming enzymes to act on aqueous solutions containing maltooligosylsucrose.

Abstract: Type-specific capsular polysaccharide preparations from Streptococcus pneumoniae, having on average less than about 1000 oligosaccharide repeat units per molecule, polydispersities between 1.0 and 1.4, intrinsic viscosities between 0.6 and 3.0 dL/g, and less than 3% contamination of type-specific polysaccharide by group-specific C-polysaccharide, are produced by a novel process. The novel type specific polysaccharide products are useful in the preparation of vaccines, especially covalent conjugates comprising the novel polysaccharide linked to a T-cell stimulatory carrier protein. Vaccines comprising the novel polysaccharides are useful in the prevention of infection and of diseases associated with infection by Streptococcus pneumoniae.

Abstract: Disclosed is a novel amylase which mainly forms maltohexaose and maltoheptaose when reacted with starch, but does not substantially hydrolyze maltohexaose and an oligosaccharide of lower molecular than maltohexaose. The amylase can be prepared from microorganisms of the genus Alcaligenes, and has a relatively-high optimum temperature and thermal stability, as well as a relatively-wide range of optimum pH and pH stability. By using the amylase, saccharide compositions rich in maltohexaose and/or maltoheptaose or those rich on maltohexaitol and/or maltoheptaitol can be readily prepared in an industrial scale, and the saccharide compositions thus obtained can be used in a variety of food products, cosmetics and pharmaceuticals.

Abstract: A method for enzymatically separating the non-inked cellulose fibers from the inked cellulose fibers in cellulosic materials. The cellulosic material, such as newsprint, is introduced into a first chamber containing a plastic canvas basket. This first chamber is in fluid communication, via plastic tubing, with a second chamber containing cellobiase beads in a plastic canvas basket. Cellulase is then introduced into the first chamber. A programmable pump then controls the flow rate between the two chambers. The action of cellulase and stirring in the first chamber results in the production of a slurry of newsprint pulp in the first chamber. This slurry contains non-inked fibers, inked fibers, and some cellobiose. The inked fibers and cellobiose flow from the first chamber to the second chamber, whereas the non-inked fibers remain in the first chamber because they are too large to pass through the pores of the plastic canvas basket. The resulting non-inked and inked fibers are then recovered.

Abstract: The invention provides a method for preparation of a bifidobacteria-nourishing medium by subjecting a saccharide-based feedstock containing fructosyl units to flash flow conditions.

Preferably, the shearform matrix is treated by subjecting it to acid thermolysis conditions. Also provided is a method of nourishing mammalian alimentary tract for preferential growth of bifidobacteria. In addition, there is provided a medium for nourishing bifidobacteria and comestible products made therefrom.
