Fig. 2From: Screening for efficient nitrogen sources for overproduction of the biomass of the functionally probiotic L. plantarum strain RPR42 in a cane molasses-based mediumThe full 24 factorial design used for optimization of the biomass production of strain RPR42 in various concentrations of cane molasses as the carbon source versus WGE as the nitrogen source (Additional file 1: Table S1). The averages for the triplicate dry biomass weights are presented and finally values rounded to the nearest 0.00–0.09Back to article page
