The bacterial cell cycle has been extensively studied under standard growth conditions. How it is modulated in response to environmental changes remains poorly understood. Here, we demonstrate that the freshwater bacterium Caulobacter crescentus blocks cell division and grows to filamentous cells in response to stress conditions affecting the cell membrane. Our data suggest that stress switches...

An unsupervised protest based division, joining an adjusted mean-move (MS) and a novel least spreading over tree (MST) based bunching methodology of remotely detected satellite pictures has been proposed in this correspondence. Morphological operations are used to get the enhanced image. The picture is first pre-prepared by a changed rendition of the standard MS based division which safeguards ...
