Antibiotic sensitivity of Micrococcus radiodurans.
A wild-type strain of Micrococcus radiodurans and its nonpigmented mutant W(1) were tested for sensitivity to 10 antibiotics selected from the standpoint of their mechanism of action. Representatives of groups of antibiotics inhibiting deoxyribonucleic acid (DNA) synthesis, DNA-dependent ribonucleic acid synthesis, protein synthesis, and cell wall synthesis were selected. M. radiodurans and its...
متن کاملTopographic study of the cell surface of micrococcus radiodurans.
The paracrystalline outer membraneous layer (HPI layer) of Micrococcus radiodurans has been investigated by negative- and positive-staining electron microscopy and subsequent digital image processing. The subunit structure of the major HPI layer protein complex and the lipid-protein distribution in the plane of the membrane have been determined. The HPI layer was found to be highly asymmetric i...
متن کاملMorphology and chemistry of cell walls of Micrococcus radiodurans.
Walls of the pigmented strain of Micrococcus radiodurans showed several layers in the electron microscope. These layers include an outermost network structure removed by trypsin, a fragile soft layer containing hexagonally packed subunits, and a rigid layer penetrated by numerous holes. The two inner layers were separated by a process of autolysis, trypsin treatment, and gradient centrifugation...
متن کاملA Comparison of Radiation Induced Lipid Changes in Micrococcus radiodurans
approved: All1111ML. Anderson Quantity variations in pigments and lipid classes were determined following yirradiation of Micrococcus radiodurans, Sarcina lutea, and Pseudomonas aeruginosa. Pigmentation was determined by extraction with organic solvents and measured as optical density at 475 mμ for M. radiodurans and S. lutea, and 410 mμ for Ps E aetuginosa. Pigments of M. radiodurans and S. lu...
متن کاملDeoxyribonucleic acid-protein ratio and radioresistance in Micrococcus radiodurans.
Cessation of exponential growth of Micrococcus radiodurans heightens X-radioresistance while either increasing or decreasing the deoxyribonucleic acid-protein ratio.
