Adaptive Laboratory Evolution of Probiotics toward Oxidative Stress Using a Microfluidic-Based Platform.

Adaptive laboratory evolution (ALE) can be used to make bacteria less susceptible to oxidative stress. An alternative to large batch scale ALE cultures is to use microfluidic platforms, which are often more economical and more efficient. Microfluidic ALE platforms have shown promise, but many have suffered from subpar cell passaging mechanisms and poor spatial definition.

Efficacy of a Sonicating Swab for Removal and Capture of Microorganisms from Experimental and Natural Contaminated Surfaces.

Enhancements in swabbing technology to increase sample collection efficacy would benefit the food industry. Specifically, these enhancements would assist the food industry in implementing the FDA Food Safety Modernization Act (FSMA) requirements by improving environmental monitoring effectiveness. A sonicating swab device, an example of an enhanced swabbing technology, was demonstrated previously to remove biofilm from stainless steel more efficiently than a standard cotton swab.
