Fig. 3From: Cost-effective production of alginate oligosaccharides from Laminaria japonica roots by Pseudoalteromonas agarivorans A3Three-dimensional plots of the effect of four variables on the alginate lyase production of strain A3. AÂ interaction of fermentation temperature and NH4NO3 concentration. BÂ Interaction of pH and NH4NO3 concentration. CÂ Interaction of inoculum size and NH4NO3 concentration. DÂ Interaction of pH and fermentation temperature. EÂ Interaction of inoculum size and fermentation temperature. FÂ Interaction of inoculum size and pH. When the effect of 2 variables was plotted, the other variables were set at the central levelBack to article page
