Saccharomyces cerevisiae genome shuffling through recursive population mating leads to improved tolerance to spent sulfite liquor.

abstract：:Treatment of Pseudomonas aeruginosa PAO1 flow biofilms with a D-amino acid mixture caused significant reductions in cell biomass by 75% and cell viability by 71%. No biofilm disassembly occurred, and matrix production increased by 30%, thereby providing a thick protective cover for remaining viable or persister cells....

It uses fabric boot socks worn over walkers' shoes to allow the collection of composite samples over large areas. Wide-area sampling is better suited to studies focusing on human exposure to pathogens (e.g., recreational walking). Thi...
