Question

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. (-5[1])Three of these chemicals spanning a wide range of HLB values are added to mineral oil and vortexed to encapsulate biomolecules (10[1])for in vitro evolution. (-5[1])Nonionic examples of these chemicals (-5[1])that are often (10[1])used (10[1])to foam up enzyme (10[1])buffers (10[1])include Triton X-100 (10[2])and Tween. (10[2]-5[1])Proteins (10[1])are coated with one of these chemicals (10[1])to provide (10[1])a uniform negative charge before polyacrylamide gel electrophoresis. For 10 points, (10[1])SDS is an example of what chemicals (10[1])that form (10[1])micelles in solution (10[1])and decrease surface tension? (10[1])■END■ (10[3]0[1])

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]
