Swarming ring patterns in bacterial colonies exposed to ultraviolet radiation.
We report a novel morphological transition in a Bacillus subtilis colony initially growing under ambient conditions, after ultraviolet radiation exposure. The bacteria in the central regions of the colonies are observed to migrate towards the colony edge forming a ring during uniform spatial exposure. When the radiation is switched off, the colonies were observed to grow both inward into the ev...

Comment on " Swarming Ring Patterns in Bacterial Colonies Exposed to Ultraviolet Radiation " In an interesting experiment, Delprato et al. [1] observed pattern formation by colonies of soil bacteria Bacillus subtilis exposed to ultra violet (UV) radiation on a 2-dimensional surface. Under spatially uniform UV radiation exposure (30 W/m 2) the population, initially uniformly distributed over a n...
متن کاملSwarming dynamics in bacterial colonies
We determine and relate the characteristic velocity, length, and time scales for bacterial motion in swarming colonies of Paenibacillus dendritiformis growing on semi-solid agar substrates. The bacteria swim within a thin fluid layer, and they form long-lived jets and vortices. These coherent structures lead to anisotropy in velocity spatial correlations and to a two-step relaxation in velocity...
متن کاملPasteurella Pseudotuberculosis 'Swarming Colonies'
at room temperature (70? to 80?F.) it grows in the form of spreading colonies similar to the ' swarming' Proteus colonies. When incubated at 37?C., the growth is limited to the area of the inoculum. At room temperature the growth continues to spread for three days. If a plate that has been incubated at room temperature and shows a spreading form of growth is subsequently incubated at 37?C., the...
متن کاملPatterns of DNA damage and photoinhibition in temperate South-Atlantic picophytoplankton exposed to solar ultraviolet radiation.
Natural marine phytoplankton assemblages from Bahía Bustamante (Chubut, Argentina, 45 degrees S, 66.5 degrees W), mainly consisting of cells in the picoplankton size range (0.2-2 microm), were exposed to various UVBR (280-315 nm) and UVAR (315-400 nm) regimes in order to follow wavelength-dependent patterns of cyclobutane pyrimidine dimer (CPD) induction and repair. Simultaneously, UVR induced ...
