Binding of Dissolved Strontium by Micrococcus luteus.
Resting cells of Micrococcus luteus have been shown to remove strontium (Sr) from dilute aqueous solutions of SrCl(2) at pH 7. Loadings of 25 mg of Sr per g of cell dry weight were achieved by cells exposed to a solution containing 50 ppm (mg/liter) of Sr. Sr binding occurred in the absence of nutrients and did not require metabolic activity. Initial binding was quite rapid (<0.5 h), although a...
متن کاملDegradation of Pyridine by Micrococcus luteus Isolated from Soil.
An organism capable of growth on pyridine was isolated from soil by enrichment culture techniques and identified as Micrococcus luteus. The organism oxidized pyridine for energy and released N contained in the pyridine ring as ammonium. The organism could not grow on mono- or disubstituted pyridinecarboxylic acids or hydroxy-, chloro-, amino-, or methylpyridines. Cell extracts of M. luteus coul...
متن کاملA new antibiotic,, asukamycin, produced by Streptomyces.
Asukamycin, a new antibiotic, has been isolated from the culture broth of a streptomycete designated as Streptomyces nodosus subsp. asukaensis. The antibiotic inhibits the growth of Gram-positive bacteria including Nocardia asteroides. The empirical formula of antibiotic asukamycin has been proposed as C29H22N2O9 (M.W. 542). An acute toxicity of the antibiotic in mice is LD50 48.5 mg/kg by intr...
متن کاملDNA-relaxing enzyme from Micrococcus luteus.
A DNA-relaxing enzyme which catalyzes the conversion of superhelical DNA to a non-superhelical covalently closed form has been purified from Micrococcus luteus to near homogeneity by two chromatographic steps. The enzyme is a single polypeptide chain. As determined by sodium dodecyl sulfate - polyacrylamide gel electrophoresis and gel filtration on Sephadex G 150, the molecular weight is 115,00...
متن کاملA new antibiotic, setomimycin, produced by a strain of Streptomyces.
A new antibiotic, setomimycin, was isolated from the culture broth of strain AM-2947, which was identified as Streptomyces pseudovenezuelae. The compound is a weakly acidic substance, and has UV-absorption at 228, 268 and 422 nm and a molecular formula of C34H28O9 (MW 580). It is active against Gram-positive bacteria including Mycobacteria, and has antitumor activity against Sarcoma-180 solid t...
