GUIMARAES, D.P.; COSTA, F.A.A.; RODRIGUES, M.I.  e  MAUGERI, F.. Optimization of dextran syntesis and acidic hydrolisis by surface response analysis. Braz. J. Chem. Eng. [online]. 1999, vol.16, n.2, pp. 129-139. ISSN 0104-6632.  http://dx.doi.org/10.1590/S0104-66321999000200004.

The influence of some variables in the in vitro synthesis of dextran by dextransucrase from Leusconostoc mesenteroides NRRL B512F, as well as in the acidic hydrolysis of the dextran produced, were studied in order to maximize the production of clinical dextran (dextran 70 and dextran 40). The experiments were conducted using a factorial design and surface response analysis.
