Caulobacter crescentus is a Gram-negative, oligotrophic bacterium widely distributed in fresh water lakes and streams. The taxon is more properly known as Caulobacter vibrioides (Henrici and Johnson 1935).

2012年7月10日 · What is Caulobacter crescentus? Caulobacter crescentus is an aquatic Gram-negative bacterium that thrives in nutrient-poor environments and exhibits an elaborate life cycle. It features regulated changes in cell shape and surface adhesion within the context of a dimorphic cell cycle that culminates in asymmetric cell division (Figure 1).

First isolated and classified in the 1960s, Caulobacter crescentus has been instrumental in the study of bacterial cell biology and differentiation. C. crescentus is a Gram-negative alphaproteobacterium that exhibits a dimorphic life cycle composed of two distinct cell types: a motile swarmer cell and a nonmotile, division-competent stalked cell.

2010年8月20日 · Caulobacter crescentus is a rod-shaped single-celled organism found in fresh water, soil and sea water. Often flourishing in low nutrient environments, this gram-negative bacterium undergoes a dimorphic life cycle that is beneficial in its competitive surroundings.

Caulobacter crescentus (referred to as Caulobacter) is a Gram-negative α-proteobacterium that inhabits nutrient-poor aquatic environments, a lifestyle facilitated by its dimorphic developmental cycle and curved-rod morphology.

2020年10月5日 · Caulobacter crescentus is a species that has met this need effectively, as its dimorphic lifestyle showcases distinctive features, including cellular asymmetry and differentiation during the cell cycle. Studying C. crescentus has reformed our understanding of bacterial intracellular organization, cellular development, and cell-cycle regulation.

Summary: Caulobacter crescentus is an aquatic Gram-negative alphaproteobacterium that undergoes multiple changes in cell shape, organelle production, subcellular distribution of proteins, and intracellular signaling throughout its life cycle.

2020年10月5日 · In this Primer, Govers and Jacobs-Wagner discuss the use of Caulobacter crescentus as a model system for studies of bacterial cell biology, cell-cycle regulation, cell asymmetry, morphological diversity, bacterial biophysics and biotechnology.

What is Caulobacter crescentus? Caulobacter crescentus is an aquatic Gram-negative bacterium that thrives in nutrient-poor environments and exhibits an elaborate life cycle. It features regulated changes in cell shape and surface adhesion within the context of a dimorphic cell cycle that culminates in asymmetric cell division (Figure 1). Why ...

To understand the mechanism of bacterial shape maintenance, we investigate the morphology of Caulobacter crescentus, which is a Gram-negative bacterium that adopts a helical crescent shape. It is known that crescentin, an intermediate filament homolog of C .
