TERM 1 Bacillus globisporus and Flavobacterium DEFINITION 1 psychrophile (cold loving) grow best at temp of 15-20 degrees celsius. TERM 2 Xanthomonas pharmicola DEFINITION 2 facultative psychrophiles - grows best below 20 degrees C but also can grow above that temperature. Play a role as pathogens in spoiled food. TERM 3 Listeria sp. DEFINITION 3 facultative to psychrotolerant - exists in spoiled FROZEN foods TERM 4 Escherichia DEFINITION 4 mesophiles; includes most bacteria, growth between 25 and 40 deg. C. Most human pathogens are in this category. TERM 5 Thermoduric organisms DEFINITION 5 ordinarily live as mesophiles but can withstand short periods of high temps. TERM 6 Thermus DEFINITION 6 typical thermophile 50-60 deg C. TERM 7 bacillus stearothermophilus and Thermococcus DEFINITION 7 obligate thermophile TERM 8 thiobacillus sp. DEFINITION 8 acidophile TERM 9 agrobacterium sp. DEFINITION 9 alkaliphile TERM 10 Pseudomonas sp. DEFINITION 10 obligate aerobe
