A scientist placed a racemic mixture of tartaric acid in a beaker and later found it was growing moldy. He filtered off the mold andfound the solution now rotated the plane of polarized light. The mixture did not rotate the plane of polarized light before. How had the mold changed the solution to become optically active?
