“…The phenotypic variation and loss of viability of fungi included in the MEED was most pronounced in those cells exposed to 254 nm [8], which is similar to mutagenic effects of UV irradiation at specific wavelengths observed in non-space systems. Likewise, reduced viability was observed in fungal cells housed in dry cuvettes as compared with those cells housed in wet cuvettes [8,12]. Viability was increased for yeast cells exposed to UV radiation at 254 nm if irradiated cells were subsequently stored in a liquid environment for several days [13,14].…”

“…S. cerevisiae ATCCy2439 was selected for space flight studies from organisms during pre-flight analyses [8]. MEED isolates used in the present study were selected because of alterations in colony morphology [2] and varied responses to induce lesions in compromised mice [9].…”

“…Space-exposed conidia were allowed to develop colonies on Sabouraud dextrose agar. Phenotype selection and survival counts were made immediately after colony development (19). Weightlessness and the stresses related to launch and splashdown produced no variation in viability as indicated in ground control, vibration control, and darkness or flight control.…”

Total lipid extracted from wild-type Trichophyton terrestre CDC-X285 Was found to be 2.0% of the dry cell weight. The total lipid contained the following phospholipid components identified by silicic acid-impregnated thin-layer and paper chromatography: phosphatidyl inositol, phosphatidyl choline, phosphatidyl serine, and phosphatidic acid. The total lipid extracted from the phenotype T. terrestre 7048-1 isolated from the Apollo 16 Microbial Ecology Evaluation Device (MEED) was found to vary according to the time at which the phospholipids were extracted. The Trichophyton phenotype was selected from a cuvette housed in the MEED exposed to specific space parameters including ultraviolet light of known wavelengths and energy levels in deep space. The phospholipid components identified in the phenotype were phosphatidyl ethanolamine and cardiolipin. The major lipid fraction was composed of digalactosyl diglyceride and monogalactosyl diglyceride. An unusual lipid was detected in the phenotype, which appeared to be sterol glycoside.

The postflight phase of the Apollo MEED mycology attempts to identify survival according to exposure to specific quantitative space flight factors, while the second phase of studies identifies qualitative change other than cell survival [57]. Initial changes incurred in space on a fungal cell can be monitored and further examined on return of the fungal species test system to Earth. The postflight studies present a better understanding of the space environmental influences on living cells and a more clear understanding of the fungal species under examination.
