However, the mode and mechanism of division also help influence the type of shape that a given type of bacteria will have. For Streptococcus pneumoniae, as is the case with the other diplococci bacteria, division occurs in the parallel plane perpendicular to the long axis. ...
When fluid flows over a solid surface, friction or drag with the surface creates a layer of fluid that is essentially stationary, this is the boundary layer. Molecules move in and out of the boundary layer predominantly by diffusion rather than by ...
Cancer cells originate from a series of acquired genetic mutations that can drive their uncontrolled cell proliferation and immune evasion. Environmental factors, including the microorganisms that colonize the human body, can shift the metabolism, growth pattern and function of neoplastic cells and shape...
Louis Pasteur demonstrated in 1859 that the fermentation process is caused by the growth of microorganisms, and that this growth is not due to spontaneous generation. (Yeasts and molds, commonly associated with fermentation, are not bacteria, but rather fungi.) Along with his contemporary, Robert ...
In a–c, we chose in each of them one motile bacterium, with a distinct angular speed Ω, from a population that includes motile as well as non-motile bacteria, and display its trajectory. The different panels illustrate the presence of different types of bacterial trajectories. d At short ...
Biofilm formation is a natural bacterial process that starts by clinging to a surface. The formation of biofilm is the result of the survival strategy of bacteria against stress conditions in the environment. Although biofilm generation is a slow process, it is natural and provides higher cell ...
with a nutrient-rich environment. Various environmental factors are responsible for the composition of the microbial community within these biofilms [18]. When microplastics enter into aquatic environment, they act as suspended particulate matter that have the ability to adsorb inorganic nutrients and ...
Cell biology - edited by Patricia C Zambryski and Karl J Oparka VolkerLipka,RalphPanstruga, inCurrent Opinion in Plant Biology, 2005 It is conceivable that plant pathogens, in analogy to bacterial pathogens of mammals (reviewed in [22,23]), have evolved means to establish a compatible host–...
1c, the hatched bars indicate unbinned rpS3 genes). We found that all of the groundwater communities are distinct in phylum-level composition (Fig. 1b,c), with a strong divide between the Ag site and the pristine sites on the basis of principal component analysis (Extended Data Fig. 1...
The genomes of bacteria derived from the gut microbiome contain several pathways that mediate contact-dependent interbacterial antagonism1,2,3. Many members of the Gram-negative order Bacteroidales encode the type VI secretion system (T6SS), which facilitates the delivery of toxic effector proteins ...
