Chemically defined media supplemented with precursors for synnematin production.
result from other techniques, such as those requiring aeration of cultures. The exhaust air from such operationls must be sterilized and the most reliable means of doing this is incineration. The 1 cfm capacity of the incinerator described above is sufficient for mnost laboratory scale operations. If provision is made for cooling the exit air, the apparatus may be employed as a source of steril...
متن کاملMedium development beyond production media: Chemically defined media for transfection and single cell cultivation
Background State-of-the-art medium and feed development has proven its potential for increasing bioprocess efficiency many times. By the application of such advanced chemically defined and animal component-free formulations, in combination with recent cell lines, the yield of mammalian cell cultures was pushed to the binary gram per liter level. In this work, the current progress in designing s...
متن کاملBurkholderia pseudomallei Requires Zn(sup2+) for Optimal Exoprotease Production in Chemically Defined Media.
The effects of various medium components on exoprotease production by Burkholderia pseudomallei were studied in order to understand the production of virulence factors by this pathogenic organism. FeSO(inf4), NaCl, and MgSO(inf4) do not significantly affect exoprotease activity, and CaCl(inf2) has only a slight influence. Conversely, ZnCl(inf2) plays a fundamental role since it drastically incr...
متن کاملChemically defined media for cultivation of Naegleria gruberi.
Cultivation of amebae of the axenic strain of Naegleria gruberi, NEG-M, was achieved in media consisting entirely of chemically defined components. A complete medium that contains 31 components allows growth with yields up to 5 x 10(6) amebae per ml. A minimal medium gives lower yields but defines 22 components that are essential for continuous cultivation: 11 amino acids, 6 vitamins, hematin, ...
متن کاملCompetence factor production in chemically defined media by noncompetent cells of group H Streptococcus strain Challis.
Chemically defined media for competence factor (CF) production by group H Streptococcus strain Challis-6 are described. CF is produced by noncompetent cells in a glutamate-free medium in which the cells cannot attain competence and by cells prior to their competence development in a glutamate-containing medium. Glutamate was required for competence development, but was not necessary for growth ...
