Growth of Aux cells in Aux cellular supernatant as a [43] source of inositol. Confocal images, taken with visible light, showed that inositol requiring Aux cells cannot utilize auxotrophic cellular supernatant as a source of external inositol A. Low cell densities support this microscopic finding. Evaluating cells for continued glow under FITC, YFP, Cherry, and TRIC settings demonstrated a lack of contaminating fluorescent molecules B
