WebJul 7, 2011 · Psychromonas ingrahamii was named after John L. Ingraham, a microbiologist devoted to research on psychrophilic bacteria. Psychrophilic means “cold-loving” and psychrophilic bacteria show maximal growth at 20°C, 15°C or lower for optimal growth and 0°C or lower for minimum growth. (9,11) Psychromonas ingrahamii was monitored for … Webtures of marine psychrophilic bacteria and found that they had optimum growth tcm- pcratures from 20 to 25C, although 10 of them would grow at -7.5C.
