Which nonlactose-fermenting organism, that rarely causes human infection, grows poorly at 35°C; however, grows optimally between 20°C and 25°C?

a. Psychrobacter pulmonis
b. A. xylosoxidans
c. R. radiobacter
d. S. putrefaciens


A
Psychrobacter spp. usually grows poorly at 35°C and grows best between 20°C and 25°C. R. radiobacter optimally grows at 25°C to 28°C, but it is also capable of growth at 35°C.
