Evaluation of efficient carbon, nitrogen sources, micro and macro nutrients for dextran production by Weissella cibaria CMGDEX3 by utilizing a modified multifactorial Placket-Burman statistical design

Abstract

In the present study previously isolated Weissella cibaria CMG DEX3 capable of producing high molecular weight, water soluble dextran (Ahmed et al., 2012) is characterized for most efficient less expensive carbon, nitrogen sources, micro and macro nutrients by utilizing a multifactorial Placket-Burman statistical design for optimization of dextran production. A twelve run Plackett-Burman experimental model with slight modification was utilized to evaluate the impact of ten diverse nutrients on the production of dextran by the bacterial isolate Weissella cibaria CMG DEX3.
