Crystallization of dextran and dextran triacetate
Polymer Science U.S.S.R., 1975Abstract It was shown that dextran produced by the strain SF-4 Leuconostoc Mesenteroides is a crystalline polymer with a glass transition temperature of 140° and flow temperature of 180° Treatment of dextran with water and formamide results in crystallization of the polysaccharide and reduces the temperature of crystallization.

Dextran synthesis by immobilized dextran sucrase
Biochimie, 1980Dextran sucrase has been produced by fermentation of Leuconostoc mesenteroides NRRL B-512, with and without continuous sucrose addition to improve enzyme production. The enzyme preparation has been concentrated from the fermentation broth by ultrafiltration and purified by gel permeation chromatography on Ultrogel.

Studies on dextran and dextran derivatives
Archives of Biochemistry and Biophysics, 1968Abstract Succinyl and phthalyl esters of native (M.W. 12 × 10 7 ) and clinical dextrans (M.W. 8 × 10 4 ) May bind Cu ++ and Fe ++ ions, at neutral Ph, giving rise to undialyzable chelates. As regards copper, some information about the metal-polysaccharide bonding have been obtained by EPR analysis.

Immunology Today, 1982
Dextran, a common plasma substitute, sometimes induces life-threatening hypersensitivity reactions. In this article Wolfgang Richter and Harriet Hedin discuss recent evidence that these Type III anaphylactic reactions, caused by natural antibodies, can be abolished by pretreatment o f patients with monovalent hapten dextran.

Archives of Surgery, 1967
DEXTRANS, a mixture of glucose polymers of various size and geometry, were introduced into medicine in the early 1950's by the Swedish scientists, after a long search for a practical nontoxic plasma substitute. 1 As a byproduct of this search, it was soon found that the high fractions of dextrans produced erythrocyte aggregation, impaired ...

Studies on dextran and dextran derivatives. II. Acid hydrolysis of native dextran
Biopolymers, 1964AbstractThe kinetics of the depolymerization of native dextran in dilute hydrochloric acid at different temperatures has been followed by measurements of M̄w, M̄n, [η], 〈ρ2〉1/2, and S. The data allow the correlation of the various parameters of the total hydrolyzate at various degrees of depolymerization. At a first approximation the results conform to

Publisher Summary This chapter discusses dextrans of commercial interest and in particular, the dextran from Leuconostoc mesenteroides NRRL B-512(F). Dextran is produced in most developed countries, primarily for clinical products. Good yields of native dextran are dependent on vigorous growth of the organism, optimal elaboration of the enzyme, and ...
