Abstract: | Summary The effects of a non-ionic surfactant, Pluronic F-68, on growth of microbial cell cultures have been studied. Growth ofSaccharomyces cerevisiae at 30°C or 37°C as measured by viable cell counts was unaffected by culture with pluronic. However, corresponding absorbance measurements forS. cerevisiae incubated with 5–10% pluronic were lower than controls at both temperatures. Absorbance ofE. coli cultures was also significantly reduced by incubation with 5.0–10.0% pluronic at both temperatures although viable counts again revealed no significant inhibition of growth. |
