This can be achieved by using a wide range of techniques from classical “one-factor-at-a-time” to modern statistical and mathematical techniques, viz. J. Antibiot. Regulation of biosynthesis of bacilysin by Bacillus subtilis. doi: 10.1007/978-1-4612-4380-9_8. If mutant strains are available they should also be explored in the medium optimization studies, as they might give us a way to develop new process, where a totally new cheap medium can be used. In this methodology, sometimes the optimum point may be missed completely, thus it requires a large number of experiments to determine the optimum level, which becomes laborious, time consuming, and uneconomical most of the time (Gupte and Kulkarni, 2003). Usually, enhanced productivity can be achieved either by strain improvement or by optimizing the process parameters. In this method, several medium factors or components are compared simultaneously and the effects are observed and ranked based on the results. World's Best PowerPoint Templates - CrystalGraphics offers more PowerPoint templates than anyone else in the world, with over 4 million to choose from. (2003) described the time consumed and cost involved in the analysis of large number of variables as the major disadvantages of OFAT techniques. An overview of the strategy and tactics of Taguchi. Such types of techniques are commonly called as DOE. Sci. Statistical optimization of medium components for the production of chitinase by Alcaligenes xylosoxydans. Neural network can perform on problems which have non-linear programs/relationships. Aggarwal, A., and Singh, H. (2005). Likewise, during the initial studies of medium optimization for antibacterial metabolite production from Streptomyces sp, we have used PBD to identify the most effective components in the media and reported soybean meal, calcium carbonate, and potassium phosphate can significantly increase the antibiotic production (Banga et al., 2008). When a large number of variables are involved, the development of rigorous models for a given biological reaction system on physical and chemical basis is still a critical challenge. With this drawback and Catch-22 situation, various new methods have been suggested and investigated, where both the medium design and strain improvement can be carried out simultaneously. Recently, Muhammad et al. Real relationship between the medium parameters and productivity is very difficult to understand thus creates hurdles in optimizing the pharmaceutical formulation. The interaction between the factors can be estimated systematically in DOE (Haaland, 1989). The quantity and quality of nutrients available and the ability to assimilate successfully are the major determinants of microbial nature and its metabolic activity. (2011). 17, 94–102.

An example of PBD has been given in Table 3. 162, 114–119. This point is often replicated in order to improve the precision of the experiment; star points, experimental runs identical to the center points except for one factor, which will take on values both below and above the median of the two factorial levels.

For example, during the study of rate of methane and carbon dioxide gas production from Methanosarcina barkeri bacterium growing on methanol, medium optimized through experimental design was found to give 1.3 times more gas production as compared to the OFAT optimized medium (Silveira et al., 1991). DNS 32, had been proved to be a valuable tool for the strain production. Eng.

(2003). Experimental error is estimated by calculating the variance among the dummy variables as follows: Veff = ∑(Ed2)/n; where Veff = variance of the concentration effect, Ed = effect for dummy variable and n = number of dummy variables. Nelder Mead (NM) simplex method is another statistical technique, which has been found to be helpful in reducing the expenses of classical optimizations and gives satisfactory results. Singh and Tripathi, employed RSM for olivanic acid production and optimized the concentration of soybean meal, CaCO3 and glycerol and found 8-folds higher product formation as compared to the control un-optimized medium (Singh and Tripathi, 2008). They used GA and NMDS separately to optimize the fermentation parameters, like, air flow rate and stirring rate of bioreactor for maximum actinomycin D production. Various microorganisms have been reported to produce an array of primary and secondary metabolites, but in a very low quantity. J. Biotechnol.

Even though widely employed with much success, some limitations are associated with RSM, for e.g., the prediction of responses based on second-order polynomial equation is often limited to low levels and results in poor estimation of optimal formulations (Baishan et al., 2003). doi: 10.1023/A:1010356231673. Carbon is the most important medium component, as it is an energy source for the microorganisms and plays an important role in the growth as well as in the production of primary and secondary metabolite. Overall, this review will provide the rationale for the selection of suitable optimization technique for media designing employed during the fermentation process of metabolite production.

Recent concerns about the genetically modified microorganism have put a big question mark on the use of recombinant microbes in large scale fermentation. Many studies claim substantial improvements over media obtained using OFAT techniques by using DOE methods. For designing a production medium, the most suitable fermentation conditions (e.g., pH, temperature, agitation speed, etc.) Currently, there is a very little knowledge available about the role of factors, their levels in controlling the metabolite (e.g., antibiotics, acids) production by different strains. 10, 1–15. Chem. Eng. Castro, P. M., Hayter, P. M., Ison, A. P., and Bull, A. T. (1992). Nearly, 1.5-folds actinomycin D production was increased as compared to the optimum point in a shake-flask experiment (1.26 to ~2 gm/L). During the medium designing and optimization, there are various strategies available which are frequently used to improve the efficiency of the production medium. doi: 10.1007/s00253-010-2835-5, Lebrihi, A., Lamsaif, D., Lefebvre, G., and Germain, P. (1992). Microbiol. (2010). Strategies for improving fermentation medium performance: a review. Table 1. Detailed knowledge of metabolic flux and its regulation could be helpful to design a medium or the performance of mathematical models with greater accuracy. Rational experimental design and statistical evaluation of the results increase the knowledge about the reliability of the information obtained during the experiments. The optimization is possible due to an automatic and repeated exchange of variables between Matlab optimization algorithm and pyruvic acid obtaining process simulation with SuperPro Designer. Therefore, the production medium with all the required components in appropriate concentration is required for the production of desired metabolite at large scale. Antonie Van Leeuwenhoek.

For two dimensions, the simplex should be an equiangular triangle and for three dimensions, it should be a tetrahedron. Adinarayana, K., and Ellaiah, P. (2002). The system strategy helps in finding the experimental levels of design features while parameter designing shows the factor level and provides the paramount effects of the process, whereas the tolerance design phase improves the elemental tolerance that considerably effect the product formation (Muhammad et al., 2014). Designing a fermentation medium can be a never ending problem, as the final endpoint, e.g., yield is an arbitrary value, which is depended upon various other factors. Singh et al. Medium optimization by an orthogonal array design for the growth of Methanosarcina barkeri. (2007). doi: 10.1016/S0141-0229(02)00172-2, Shih, I., Van, Y., and Chang, Y.
