abstract

Yeast and bacteria growth has been detected by observing light diffracted from specially prepared diffracting screens upon which these organisms were grown. The screens were fabricated by impressing patterns on the surface of a growing medium. As the microbes metabolized, they caused severe changes in the lightdiffracting properties of the patterns as they ate into them. Such changes were detected within twenty minutes for bacteria and ten minutes for yeast.
