Description
Summary:The effects of various combinations of environmental factors on phosphorous (P) content in the salt-tolerant green algae Dunaliella were studied, using laboratory cultures under controlled conditions. The factors examined were the cultivation temperature, light intensity, P and NaCl concentration, and nitrogen (N): P atomic ratios in the culture, and P concentration in the preculture. The experimental system of environmental factors and the measured response of algal P content was modeled through the response surface method. The model obtained revealed that the intracellular P content in D. parva was highly dependent on the P concentration in the preculture medium under the experimental domain studied.
