Flagella is the organelle involved in motility of Salmonella and plays an important role in colonization of Salmonella. Flagellins is the structural subunits of flagellar filament that is known as an adjuvant. Recombinant production of flagellin of S. enteritidis is advantageous due to the removal of pathogenic microorganism from the production process and improved process safety. E.coli is an appropriate host for the expression of recombinant proteins. However, its major obstacle is the formation of inclusion bodies. Inclusion bodies are aggregated inactive proteins and the recovery of proteins in the active form from these aggregates usually has a low yield. Therefore, the objective of our... 

Today, the use of controllable swimmer micro-robots has expanded from micro to macro-scale dimensions due to their many applications. These robots, as a result of their small size and dimensions, have the ability to access limited and complex environments. Considering the various applications of such swimmers, it can be said that in addition to the necessity of well designing and implementation, their maneuverability and controllability are among the most important research areas on these swimmers. Regarding the dimensions and technologies needed for these robots, various methods for designing and implementing them are suggested, which are mostly inspired by the nature of microorganisms. In...
