A saddle-shaped antibiotic that behaves like one of these chemicals is a lipo-heptapeptide derived from B. subtilis. These chemicals are detected and removed from the efflux of wastewater treatment plants by reacting them with methylene blue. Bio-derived examples of these chemicals include rhamnolipids. Three of these chemicals spanning a wide range of HLB values are added to mineral oil and vortexed to encapsulate biomolecules for in vitro evolution. Nonionic examples of these chemicals that are often used to foam up enzyme buffers include Triton X-100 and Tween. Proteins are coated with one of these chemicals to provide a uniform negative charge before polyacrylamide gel electrophoresis. For 10 points, SDS is an example of what chemicals that form micelles in solution and decrease surface tension? ■END■
ANSWER: surfactants [or detergents; or surface-acting agents; accept non-ionic surfactants, ionic surfactants, cationic surfactants, or anionic surfactants; accept surfactin; accept saponins; prompt on soaps or emulsifiers or amphiphiles]
