Microstructure of colonies of rod-shaped bacteria.
Whole colonies of Bacillus cereus, B. megaterium, B. mycoides CN2495, Corynebacterium hofmanni NCTC1938, Escherichia coli, Lactobacillus acidophilus NCIB1899, Nocardia graminis NCTC4728, Pseudomonas viscosa, and Serratia marcescens were prepared for scanning electron microscopic examination by freeze-drying and metal-coating. The arrangement of individual cells within colonies could be seen. Ce...
متن کاملBistable protein distributions in rod-shaped bacteria
The distributions of many proteins in rod-shaped bacteria are far from homogenous. Often they accumulate at the cell poles or in the cell center. At the same time, the copy number of proteins in a single cell is relatively small making the patterns noisy. To explore limits to protein patterns due to molecular noise, we studied a generic mechanism for spontaneous polar protein assemblies in rods...
متن کاملPurification and properties of an S-type pyocin, pyocin AP41.
Pyocin AP41, a protease-sensitive bacteriocin produced by Pseudomonas aeruginosa PAF41, was purified to a homogeneous state and characterized. The molecular weight of this pyocin was about 95,000 as determined by the combination of gel filtration and sedimentation velocity analysis. This pyocin was a complex of two kinds of polypeptides. Highly purified preparations showed two protein bands on ...
متن کاملHybrid organic-inorganic, rod-shaped nanoresistors and diodes.
The electrical properties of template-synthesized three- and four-component rodlike nanostructures consisting of metal and conducting polymer domains have been studied. These structures behave like nanometer-scale resistors and diodes, depending upon their compositions and spatial distribution of the different compositional blocks. In the two-component systems, the conducting polymer block dict...
متن کاملContrasting mechanisms of growth in two model rod-shaped bacteria
How cells control their shape and size is a long-standing question in cell biology. Many rod-shaped bacteria elongate their sidewalls by the action of cell wall synthesizing machineries that are associated to actin-like MreB cortical patches. However, little is known about how elongation is regulated to enable varied growth rates and sizes. Here we use total internal reflection fluorescence mic...
