This paper describes the nutrient requirements of microalgae (ie carbon, nitrogen and
phosphorus as well as other macro-and micronutrients, chelates and water) as well as …

Photosynthesis by phytoplankton cells in aquatic environments contributes to more than
40% of the global primary production (Behrenfeld et al., 2006). Within the euphotic zone …

Microalgal are capable of many kinds of trophy, being autotrophy and/or heterotrophy, and
various combinations are possible between these two major forms of nutrition. Growth media …

Depletion of stratospheric ozone, the principal atmospheric attenuator of ultraviolet-B (UVB)
radiation, by man-made chemicals has raised scientific and public concern regarding the …

The productivity of aquatic primary producers depends on a number of biotic and abiotic
factors, such as pH, CO2 concentration, temperature, nutrient availability, solar UV and PAR …

The effects of nitrogen source (N2, NO3− and NH4+) on scytonemin synthesis were
investigated in the heterocystous cyanobacterium Nostoc punctiforme PCC 73102. With the …

Abstract From June to September 2005, we carried out experiments to determine the
ultraviolet radiation (UVR)‐induced photoinhibition of summer phytoplankton assemblages …

Light is a major determinant not only for carbon (C)-fixation in autotrophs, but also for the
cellular proportions of major elements like C, nitrogen (N) and phosphorus (P). High …

UV radiation is known to inhibit photosynthetically active radiation (PAR)‐driven
photosynthesis; however, moderate levels of UV‐A have been shown to enhance …

Over the past four decades, mesocosm studies have been successfully used for a wide
range of applications and have provided a lot of information on trophic interactions and …
