1959 Bacteriol. Rev. 23 98/2 The recognition that low temperatures are not optimum for organisms that grow at 0°C led to the introduction of several other names as replacement for psychrophile. These included..psychro-tolerant.
1970 Sci. Jrnl. May 19 Slime is caused by cold resistant, or psychrotolerant, bacteria which are not a health hazard but which produce an objectionable smell.
2000 Ann. Missouri Bot. Garden 87 8/1 These [microorganisms] are usually psychrotolerant, meaning that although they are capable of growth in the cold, they grow better at warmer temperatures.
