V. Algal Growth Media

Question 1

how many criteria for optimal algae media are there and what are they?

Answer 1

5 –> light, CO2, macronutrients (N, P), micronutrients (Fe, Mg, Ca), optimal pH

Question 2

role(s) of light for algae?

Answer 2

photosynthesis

Question 3

role(s) of CO2 for algae?

Answer 3

source of carbon for photosynthesis

Question 4

role(s) of macronutrients for algae?

Answer 4

• nitrogen (as nitrate or ammonium): protein and nucleic acid formation
• phosphorus (as phosphate): involved in ATP production and cell wall formation

Question 5

role(s) of micronutrients for algae?

Answer 5

iron, magnesium, calcium
support enzyme activity and chlorophyll structure

Question 6
