TLDR
Chlorophytes were significantly more tolerant to high ammonium than diatoms, prymnesiophytes, dinoflagellates, and raphidophytes which were the least tolerant and toxicity is likely associated with the ammonium ion rather than ammonia.About:

Journal ArticleDOI
Pluses and minuses of ammonium and nitrate uptake and assimilation by phytoplankton and implications for productivity and community composition, with emphasis on nitrogen-enriched conditions
Patricia M. Glibert,Frances P. Wilkerson,Richard C. Dugdale,John A. Raven,John A. Raven,Christopher L. Dupont,Peter R. Leavitt,Alexander E. Parker,JoAnn M. Burkholder,Todd M. Kana +9 more
TL;DR: Relationships between NH4+ and NO3− metabolism have important implications for harmful algal blooms, development of nutrient criteria for management, and modeling of nutrient uptake by phytoplankton, particularly in conditions where eutrophication is increasing and the redox state of N loads is changing.
Journal ArticleDOI
Eutrophication, harmful algae and biodiversity - Challenging paradigms in a world of complex nutrient changes.
TL;DR: The underlying message is that nutrient proportions and forms can alter biodiversity, even when nutrients are at concentrations in excess of those considered limiting.

Wastewater treatment using microalgae: how realistic a contribution might it be to significant urban wastewater treatment?
F. Gabriel Acién,Cintia Gómez-Serrano,Maria del Mar Morales-Amaral,José M. Fernández-Sevilla,Emilio Molina-Grima +4 more
TL;DR: Microalgae have been proposed as an option for wastewater treatment since the 1960s, but still, this technology has not been expanded to an industrial scale, and the major factors limiting the performance of these systems are analysed.

Bio-mitigation of carbon dioxide using microalgal systems: Advances and perspectives
Wenguang Zhou,Jinghan Wang,Jinghan Wang,Paul Chen,Ji Chengcheng,Qiuyun Kang,Bei Lu,Kun Li,Jin Liu,Roger Ruan,Roger Ruan +10 more
TL;DR: This present review is aimed to gain understanding how microalgae assimilate different forms of carbons and provide a comprehensive overview of the current advances in utilizing microalgai for CO2 fixation, with focus on strain screening and improvement, mass cultivation practice, and effects of environmental and nutritional factors onCO2 fixation performance.
Journal ArticleDOI
Photobioreactors for the production of microalgae
TL;DR: This chapter summarizes the current state of the art on photobioreactor design and operation, discussing the major challenges to be solved to achieve a massive expansion of microalgae-based technologies.

TL;DR: In this paper, the authors compared the natural and anthropogenic controls on the conversion of unreactive N2 to more reactive forms of nitrogen (Nr) and found that human activities increasingly dominate the N budget at the global and at most regional scales, and the terrestrial and open ocean N budgets are essentially dis-connected.

Uptake of new and regenerated forms of nitrogen in primary productivity1
TL;DR: The role of zooplankton in regenerating nitrogen as ammonia in the Sargasso Sea is examined theoretically in this article, showing that only about 10% of the daily ammonia uptake by phytoplanton living in the upper 100 m.

The Nitrogen Cascade
James N. Galloway,John D. Aber,Jan Willem Erisman,Sybil P. Seitzinger,Robert W. Howarth,Ellis B. Cowling,B. Jack Cosby +6 more
TL;DR: The only way to eliminate Nr accumulation and stop the cascade is to convert Nr back to nonreactive N2, which leads to lag times in the continuation of the cascade.

Nitrogen, Phosphorus, and Eutrophication in the Coastal Marine Environment
TL;DR: Removal of phosphate from detergents is not likely to slow the eutrophication of coastal marine waters, and its replacement with nitrogen-containing nitrilotriacetic acid may worsen the situation.

Nutrient limitation of phytoplankton in freshwater and marine environments: A review of recent evidence on the effects of enrichment1
R. E. Hecky,Peter Kilham +1 more
TL;DR: It is concluded that the extent and severity of N limitation in the marine environment remain an open question, despite the fact that by the late seventies the evidence for P limitation had become so great that phosphorus control was recommended as the legislated basis for controlling eutrophication in North American and European inland waters.
