Four species of micro-fungi were selected for study in the National Aeronautics and Space Administration (NASA) Apollo Microbial Ecology Evaluation Device (MEED) mycology experiments. Trichophyton terrestre, Rhodotorula rubra, Saccharomyces cerevisiae and Chaetomium globosum were selected from a series of preflight test fungi for the MEED mycology studies during the 2 years prior to the actual flight (Volz, 1971a, 1972b). Conidia of T. terrestre, ascospores of C. globosum and yeast cells of R. rubra and S. cerevisiae were suspended in sterile distilled water and loaded into wet and dry cuvettes for exposure to specific space flight parameters according to the filters built into the space flight hardware (Volz, 1971b). Living cells were found in the original inocula and phenotype water storage after 27 years. Colony cells were also examined after 27 years of continuous culture. |
