Multi-fractal characterization of bacterial swimming dynamics: a case study on real and simulated Serratia marcescens
نویسندگان
چکیده
To add to the current state of knowledge about bacterial swimming dynamics, in this paper, we study the fractal swimming dynamics of populations of Serratia marcescens bacteria both in vitro and in silico, while accounting for realistic conditions like volume exclusion, chemical interactions, obstacles and distribution of chemoattractant in the environment. While previous research has shown that bacterial motion is non-ergodic, we demonstrate that, besides the non-ergodicity, the bacterial swimming dynamics is multi-fractal in nature. Finally, we demonstrate that the multi-fractal characteristic of bacterial dynamics is strongly affected by bacterial density and chemoattractant concentration.

Chitinase production by newly isolated Serratia marcescens B4A was optimized following Taguchi’sarray methods. Twenty-three bacterial isolates were screened from shrimp culture ponds in the South ofIran. A chitinase-producing bacterium was isolated based on it’s ability to utilize chitin as the sole carbonsource. The isolate designated as B4A, was identified as Serratia marces...

Representative strains of Serratia marcescens from an edible cactus plant and silkworms were characterized and a comparison based on their cellular fatty acid composition, 16S rRNA and groE gene sequence analysis as well as silkworm virulence and chitosan susceptibility was carried out. Results from this study indicate that there are no significant differences between the phenotypic and molecul...
