Abstract

SUMMARY: Of 103 species of fungi exposed to 10 atmospheres (atm.) pressure of oxygen at 25° for 7 days 52 resumed growth after treatment. Of these, 22 recovered from a similar treatment for 14 days. On resumption of growth, growth rates were the same as those of untreated colonies, after a lag period between decompression and recovery. The lag period varied with species, length of exposure, inoculum source, and in some cases between replicates of a species. More detailed investigation of the reaction of and showed that generally the lag periods increased with increasing exposure times, that their extinction points (i.e. the exposure which killed all replicates) varied, and that at exposures approaching the extinction point there was selective survival either of spores or of strains in the latter three fungi.
