It was discovered that the Caulobacter crescentus bacterium, which is often the first creature to colonize a wet surface, produces the strongest glue known to man, with an adhesive force almost three times stronger than commercial superglue.
They hope to use the substance from Caulobacter crescentus in operations - if they can stop it from sticking to all it touches.
The bacterium is called Caulobacter crescentus. When it begins its life, it's a cell with a tail, called a flagellum, which it uses to move around.
The researchers identified crescentin while studying Caulobacter crescentus, which comes in curved or helical forms, depending on its length.
This is true for Caulobacter crescentus, Mycobacterium tuberculosis, and Xylella fastidioasa (Figure 2).
Figure 2 shows that Caulobacter crescentus has regular ly higher C and lower A in the third position.
The researchers started the project by trying to understand why the bacterium Caulobacter crescentus produces two distinct types of cell - one with a flagellum (appendage) and the other without.
To overcome these difficulties, we recently developed a new enzymatic quantification method for xylose measurement in urine human samples, based on the activity of the enzyme xylose dehydrogenase from Caulobacter crescentus (XylB) (EC 1.1.1.175) [20].
