Chemical Structure Controls Soil Biotransformation Kinetics of Bacillus Lipopeptide Biopesticides

Abstract Bacillus lipopeptides (surfactins, iturins, and fengycins) are an emerging class of biopesticides. However, their fate in agricultural soils, and specifically how variations in the chemical structure such as alkyl chain length, amino acid sequence, and cyclization affect...

A Capsid Tyrosine Residue Governs the Proteolytic Inactivation of Echovirus 11 in Lakewater

Abstract Enteroviruses are environmentally transmissible human pathogens whose stability in natural waters varies widely, yet the molecular determinants underlying this variability remain largely unknown. Echovirus 11 (E11), a reemerging cause of severe neonatal infections, is ef...
