Microbial responses to microgravity and other low-shear environments

Article Abstract:

The potential future research trends aimed at understanding the effect of changes in mechanical forces that occur in microgravity and other low-shear environments on different microbial parameters. The response of microbes to changes in mechanical and physical forces is analyzed that is proposed to provide insight into a key mechanism to orchestrate and fine-tune the cellular response to environmental stimuli.

Novel quantitative biosystem for modeling physiological fluid shear stress on cells

Article Abstract:

The development of a novel model system to mathematically model the fluid shear within a modified rotating wall vessel (RWV) bioreactor to evaluate the response of plantonic cultures of Salmonella enterica serovar Typhimurium to quantified ranges of physiological fluid shear is reported.

Cloning and transfer of the Salmonella pathogenicity island 2 type III secretion system for studies of a range of gram-negative genera

Article Abstract:

The expression of the cloned Salmonella pathogenicity island 2 (SPI-2) system in different Gammaproteobacteria and Alphaproteobacteria dependent on the bacterial strain and growth medium is reported. This could offer a desired function to an engineered gram-negative strain.
