✦ Synopsis
Although GUKTER (1957) discusses t'he relationship of temperature to various marine organisms, the intimate reasons why temperature can bring about the death of cells are la'cliing. The obligately psychrophilic bacterium, Vibrio marinus MP-4, provides an opportunity t o study the effects of elevated temperature (20 to 30 "C) on a cold water organism. Such studies should provide an insight as to why temperature is an environmental parameter in the marine environment.
Elevated temperatnres between 20 and 30 "C can occur when a. water mass is upwelled in t'ropical and subtropical environments. The a'bnormal thermolability of enzymes in another strain of Vibrio marinus was demonstrated by LAKG-RIDGE and MORITA (1966), and MATHEMEIER and MORITA (1966), while thermal (20 to 30 "C) induced leakage of amino acids, proteins, ribonucleic acid (RXA) and deoxyribonucleic acid (DNA) was shown by HAIGHT and MORITA (1966). *) Published as technical paper no. 2465, Oregon Agricultural Experimental Station.
