TLDR
In this paper, the authors focus on the application, development, and practical considerations of fermentations in chemically defined media in an industrial environment and present a review of the application and process economics of such media.Abstract:
The use of chemically defined media is gaining popularity in some commercial fermentations, particularly for the preparation of biological products. Although these media are still not frequently developed for industrial processes, they do exhibit favorable characteristics at large scale that are not observed with traditional complex media. This review focuses on the application, development, and practical considerations, especially process economics, of fermentations in chemically defined media in an industrial environment.read more

Optimization of medium components for plasmid production by recombinantE. coli DH5α pUK21CMVβ1.2
TL;DR: The results indicated that sucrose and casein peptone were the most suitable carbon and nitrogen sources, respectively, for plasmid production, and thePlasmid concentration was significantly influenced by the C:N ratio.

Statistical optimization for succinic acid production from E. coli in a cost-effective medium.
TL;DR: Response surface methodology (RSM) was employed for optimization of medium components and cultural parameters in cost effective cane molasses based medium for attaining high yield of succinic acid and will definitely help in replacing existing environmentally hazardous and cost-intensive chemical methods for the production of succinyl acid.

Production and Screening of High Yield Avermectin B1b Mutant of Streptomyces avermitilis 41445 Through Mutagenesis.
TL;DR: The hereditary stability analysis of the UV mentioning 45 minutes revealed the UV exposure time for mutants and 3 represented the colony taken from the plate irradiated for 45 minutes mutant showed that the production of avermectin B1b remained constant and no reverse mutation occurred after 15 generations.

Characterization of ethanol fermentation waste and its application to lactic acid production by Lactobacillus paracasei
TL;DR: The overall lactic acid productivity in the autolyzed then distilled EFW (ADEFW) was 80 and 27 % higher than in the LGM and DEFW, respectively, in comparison with those from comparable fermentation in a lactobacillus growth medium.

Sequential Application of Simplex Designs in Optimisation and Evolutionary Operation
TL;DR: A technique for empirical optimisation is presented in which a sequence of experimental designs each in the form of a regular or irregular simplex is used, each simplex having all vertices but one in common with the preceding simplex, and being completed by one new point.
