Phosphate depletion is one of the favorable ways to enhance the sewage water treatment with the algae, however, detailed information is essential with respect to internal phosphate concentration and physiology of the algae. The growth rate of the phosphate-starved cells was reduced drastically after 48 h. Indicating cells entered in the stationary phase of the growth cycle. Fourier Transform Infrared analysis of phosphate-starved cells showed the reduction in internal phosphate concentration and an increase in carbohydrate/phosphate and carbohydrate/lipid ratio. The phosphate-starved cells, with an initial cell density of, 1 × 10 cells mL shows 87% phosphate and 100 % nitrogen removal in 24 h. The normal cells need approximately 48 h to trim down the nutrients from wastewater up to this extent. Other microalgae, , growth pattern was not affected due to phosphate starvation. The cells of was able to reduce 71% phosphate and 73% nitrogen within 24 h, with an initial cell density of, 1 × 10 cells mL.
磷缺乏是增强藻类污水处理效果的有利方法之一，然而，关于藻类内部磷浓度和生理学的详细信息至关重要。缺磷细胞的生长速率在48小时后急剧下降，表明细胞进入了生长周期的稳定期。对缺磷细胞的傅里叶变换红外分析表明，内部磷浓度降低，碳水化合物/磷和碳水化合物/脂质比率增加。初始细胞密度为1×10个细胞/毫升的缺磷细胞在24小时内显示出87%的磷去除率和100%的氮去除率。正常细胞需要大约48小时才能将废水中的营养物质减少到这个程度。其他微藻，其生长模式不受磷饥饿的影响。初始细胞密度为1×10个细胞/毫升的该微藻细胞能够在24小时内减少71%的磷和73%的氮。
