How algal growth increase total phosphorus in a culture?
Answers
Nitrogen and phosphorus support the growth of algae and aquatic plants, which provide food and habitat for fish, shellfish and smaller organisms that live in water. ... Too much nitrogen and phosphorus in the water causes algae to grow faster than ecosystems can handle.
An adequate supply of nitrogen and phosphorus is imperative to ensure high production rates in mass microalgal cultures. High yield coefficients, low crude protein contents and low productivities were measured at low supplies of these nutrients. The highest production rates were measured at N and P concentrations exceeding 25 and 2 mg litre−1 respectively, at which supply the highest crude protein contents were measured. Although the carbohydrate content followed, under certain N supply conditions, an inverse relationship with the crude protein content, it was generally not affected by changes in N and P concentrations. Scenedesmus-Chlorella types had higher crude protein contents than Monoraphidium, but the latter displayed the highest productivity.
