Studying human\u2013microbe interactions creates the need for a universal culture medium that supports fungal, bacterial, and human cell culturing, while allowing sensitive analytical approaches such as OMICs and chromatography techniques. In this study, we established a fully defined, customizable adaptation of Dulbecco\u2019s modified Eagle medium (DMEM), allowing multi-kingdom culturing of\n              <jats:italic>S. aureus<\/jats:italic>\n              ,\n              <jats:italic>C. albicans<\/jats:italic>\n              , and human oral cell lines, whereas minimal version of DMEM (mDMEM) did not support growth of\n              <jats:italic>S. aureus<\/jats:italic>\n              , and neither did supplementation with dextrose, MEM non-essential amino acids, pyruvate, and Glutamax. This new medium composition, designated as \u201cmDMEM-DMP,\u201d promoted growth of all tested\n              <jats:italic>S. aureus<\/jats:italic>\n              strains. Addition of 25 mM 4-(2-hydroxyethyl)\u22121-piperazineethanesulfonic acid (HEPES) further improved growth, while higher concentrations did not improve growth any further. Higher concentrations of HEPES did result in prolonged stabilization of medium pH. mDMEM-DMP promoted (hyphal)\n              <jats:italic>C. albicans<\/jats:italic>\n              monoculturing and co-culturing on both solid and semi-solid surfaces. In contrast to\n              <jats:italic>S. aureus<\/jats:italic>\n              , addition of HEPES reduced\n              <jats:italic>C. albicans<\/jats:italic>\n              maximum culture optical density (OD). Finally, only buffered mDMEM-DMP (100 mM HEPES) was successful in maintaining the metabolic activity of human oral Ca9-22 and HO1N1 cell lines for 24 hours. Altogether, our findings show that mDMEM-DMP is a versatile and potent culture medium for both microbial and human cell culturing, providing a customizable platform to study human as well as microbial molecular physiology and putative interactions.\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>IMPORTANCE<\/jats:title>\n            <jats:p>\n              Interaction between microbes and the host are in the center of interest both in disease and in health. In order to study the interactions between microbes of different kingdoms and the host, alternative media are required. Synthetic media are useful as they allow addition of specific components. In addition, well-defined media are required if high-resolution analyses such as metabolomics and proteomics are desired. We describe the development of a synthetic medium to study the interactions between\n              <jats:italic>C. albicans, S. aureus,<\/jats:italic>\n              and human oral epithelial cells.
