According to Menon, the new medium not only supported biomass accumulation comparable to the current medium, it also exhibited greater semi-selectivity against non-lactobacilli. "Together, these results suggest that the new medium is an acceptable alternative for use in many metabolic bioassays," she said.
Additionally, the pale yellow coloration and clarity of the new medium is significantly lighter than that of the current standard medium, know by the abbreviation MRS, which is amber in color.
"The improved coloration and clarity may also afford this new medium greater sensitivity for use in assays that measure biomass accumulation or use in molecular reporter systems," he said.
Sturino said the resultant medium will be used to identify new bioactive compounds capable of supporting the growth or activity of these important microorganisms.
"Bioactive compounds of interest might include those relevant to food and nutrition, such as in the screening for prebiotic compounds that may confer a health benefit, as well as compounds that might accelerate the production of biofuels," he said.
