Nutrients optimization was investigated by response surface methodology with central composite design (CCD).
Neither Cranney nor Chung made any apparent attempt to use co-nutrient optimization as a criterion for inclusion of a study into analysis.
Thus, among the options to enhance the agricultural sustainability, there is nutrient cycling optimization through the organic waste use (Elser and Bennett 2011) and the use of less expansive and locally available sources.
Although the processes that can be used in order to achieve the desirable results vary, they still have the same principles; the use of microorganisms or their enzymes, that are either indigenous and are stimulated by the addition of nutrients or optimization of conditions, or are seeded into the soil.
To attain this goal, different approaches including nutrient starvation, bioprocess optimization and genetic engineering can be used (Hu et al. [2008]).
Nutrient limitation conditions, optimization and comparison of polyhydroxyalkanoate (PHA) yields and biomass production by parent and mutant strains of Rhizobium meliloti were investigated.
We used published data from nine sites where nutrient and water optimization studies had been installed in a 2 × 2 factorial design to determine maximum biomass production in response to a simple set of treatments.
Salicornia spp. produced more harvestable biomass in hydroponic culture than in sand culture, but the nutrient concentration requires optimization as hydroponically grown plants showed symptoms of stress.
Glucose, (NH4 2SO4, and corn steep liquor were found to be the best nutrients for the optimization of rifamycin B productions, and central composite design experiments indicated that the optimal concentrations of these nutrients were 63 g/L, 7.9 g/L, and 10 g/L, respectively.
This chapter discusses how to develop serum-free media through optimization of nutrient composition and delivery format.
