Continuous culture of ruminal microorganisms in chemically defined medium. II. Culture medium studies.
Ruminal ciliates have been grown in continuous culture in chemically defined media and in the absence of viable bacteria. Oligotrichic ruminal ciliates seem to require insoluble carbohydrates for growth; the holotrichic ciliates require soluble carbohydrates, but at low concentrations. Both groups of ciliates utilize amino acids as their principal nitrogen source when these are supplied in micr...
متن کاملChemically defined medium for oral microorganisms.
We formulated a chemically defined medium consisting of 14 inorganic salts, 23 amino acids, 23 vitamins and other factors, seven purines and pyrimidines, and glucose which would successfully support the growth of a wide variety of oral microorganisms. Of 204 oral isolates representing 20 genera and 60 species, 197 maintained viability through six serial transfers.

Microbiol. 13:232-235. 1965.-A chemically defined medium was prepared which adequately supported growth of a vaccine strain of Pasteurella tularensis. This medium differed from those previously described in: (i) concentration of components, (ii) a ...
متن کاملP-136: In Vitro Development of Ovine Oocytes Matured in A Chemically Defined Medium
Background: Despite great advances achieved in the field of in vitro oocyte maturation (IVM), almost all IVM media are supplemented with undefined component which not only pose the risk of pathogen transmission but also hinders our knowledge of molecular mechanisms of maturation. One of these components is serum that containing various concentration of unknown molecules affecting cellular proce...
متن کاملChemically defined medium for Rothia dentocariosa.
A chemically defined medium for Rothia dentocariosa has been established. All strains tested, including the type strain, grew well in this medium. Rothia strains had a generation time of 3.5 to 4.0 h, with a yield of 62 mg (dry weight) per 100 ml after 72 h of growth in the chemically defined medium.
