The survival time of red halophiles in solutions of sodium chloride is greatest in saturated solutions and decreases with reductions in the concentration of salt. At 25 °C. heavy inoculations may survive for months in saturated brines, rarely over 24 hours in 10 per cent solutions, and for 2 to 6 hours in tap water free from salt. Increased temperature and decreased pH reduced the survival time in all of the salt concentrations tested. Various protein materials, but not sugar, had a protective action against the destructive action of decreased salt concentrations. |
