Abstract : High pressure helium-oxygen effects on microbial processes are of interest from the standpoint of spoilage and toxin production in foods; the fouling and degradation of materials stored in the habitat; possible altered pathogenicity of disease causing microorganisms; and to serve as a model system to gain information on high pressure helium-oxygen effects on biochemical processes which may relate to human cells. The present study was limited to a growth response investigation in a high pressure helium-oxygen atmosphere using representative bacteria and yeasts. This information should prove useful to predict gross microbial activity in undersea habitats compared to growth in air at 1 atm.
