New 'defined' medium for Lactobacilli

Texas A&M University System scientists from the departments of nutrition and food science and poultry science have developed a new medium for the cultivation of lactobacilli.

Prior to the development of the new medium, the nutrient compositions of media that are traditionally used to cultivate lactobacilli have been largely undefined. This lack of definition complicates the use of media when trying to identify nutrients to stimulate the growth and metabolic activity of these important microorganisms.

To develop the new medium, the overall contribution of undefined components, such as peptone, yeast extract and beef extract, was reduced by 70 percent in the final formulation.

For further details, see the following research brief.
