What organisms based on oxygen requirements produce the enzyme catalase? Obligate aerobes Facultative anaerobes

What is the chemical reaction catalyzed by catalase?

What is the chemical reaction catalyzed by catalase? 2 H2O2 2 H2O + O2

What are obligate halophiles?

What are obligate halophiles? Require high salt to grow

What are psychrophiles?

What are psychrophiles? Cold-loving organisms Grow best at optimal temperature of about 15 degrees Celsius

What organisms based on temperature grow best on you?

What organisms based on temperature grow best on you? mesophiles

What is selective media?

What is selective media? Contains an inhibitor Selects for the growth of only certain microorganisms

What type of media is blood agar?

What type of media is blood agar? Enrichment and differential

How do you classify organisms that grow best at very high temperatures?

How do you classify organisms that grow best at very high temperatures? Hyperthermophiles

Label the following growth curve
