Plant growth regulators and amino acids released by Azospirillum sp in chemically defined media.
AIMS To investigate the ability of Azospirillum sp., a facultative endophitic diazotrophic bacterium, to release plant growth regulators (PGR) such as polyamines, ethylene, indoleacetic acid and amino acids in both combined-N and N-free cultures. METHODS AND RESULTS The presence of those substances was analysed by HPLC. Azospirillum sp. is capable of releasing PGR and amino acids into the cul...
متن کاملOxytetracycline Formation by Streptomyces rimosus in Chemically Defined Media.
Details in the fermentation of oxytetracycline in a synthetic medium with Streptomyces rimosus have been presented. In these studies, an organic nitrogen source was shown to be essential for the production of significant amounts of antibiotic activity. Of the amino acids tested, aspartic acid, proline, threonine, valine, and beta-alanine were utilized well for both growth and antibiotic product...
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.
متن کاملFatty Acids Synthesized by the Action of Thiamine*
Fat which has been synthesized by rats from carbohydrates is characterized by the presence of large amounts of Cl6 fatty acids (1). In such synthetic depot fat, the total (716 acids constitute 40 to 45 per cent of the total mixed acids. The value for the Cl6 acids is approximately 25 per cent when fat is present in the animal’s diet and is being deposited directly. A particularly striking incre...

Romero, Ethel M. (Universidad Nacional de la Plata, La Plata, Argentina), and Rodolfo M. Brenner. Fatty acids synthesized from hexadecane by Pseudomonas aeruginosa. J. Bacteriol. 91:183-188. 1966.-The lipids extracted from Pseudomonas aeruginosa incubated with hexadecane in a mineral medium were separated into a nonpolar and three polar fractions by thin-layer chromatography. The fatty acid com...
