Abstract: Effects of ecological factors on metabolic rate of organic carbon(C6H12O6), NH3-N and inorganic phosphorus (IP) in an algae-bacteria ecosystem (A+B) are studied under simulated conditions.The results show that the metabolic rate of C6H12O6 in A+B ecosystem increases with decreasing ratio of bacteria (B)/algae (A) or algae/bacteria, and those of C6H12O6,NH3-N and lP are different in light and dark experiments. The average metabolic rate of C6H12O6 in dark is 12.3% higher than in light, while those of IP and NH3-N in light are respectively 14. 4% and 16.2% higher than in dark.The average metabolic rate of these three nutrient matters are all increased with increasing load of organic carbon in A+B,A and B cultures, especially in case of NH3-N.The relationship between structure and function of algae-bacteria ecosystem is also discussed in this paper.
