Abstract

DE NEVE, J. et al. A statistically motivated choice of process parameters for the improvement of canthaxanthin production by Dietzia maris NIT-D (Accession number: HM151403). Rev. Mex. Ing. Quím [online]. 2014, vol.13, n.2, pp.595-603. ISSN 1665-2738.

Dietzia maris NIT-D, a producer of canthaxanthin, is isolated during routine screening of pigment producing bacteria. The effects of process parameters, namely temperature, pH, shaker speed, percentage inoculum, medium volume, and concentration of glucose on the canthaxanthin production are studied by using response surface design methodology. The optimal conditions are temperature = 30°C, pH = 5.5), shaker speed = 125 rpm, inoculum = 1.9 %, volume = 50 mL, and glucose = 15 g L^-1, resulting in a canthaxanthin production of 152 mg L^-1, which is 25% higher than that of a recently reported study.

Keywords : Dietzia maris NIT-D; biomass; canthaxanthin; response surface methodology.
