I am looking for good literature about nitrogen limitation in algae. I would like to know what is the minimal nitrogen content necessary for survival, especially in macroalgae, but also in microalgae (for comparison).

Hm, I do not know for cultures, but for natural state and aiming at data for oligotrophic seas, Eppley et al. 1969 or MacIsaac and Dugdale 1969 in L&O or Deep sea research published that 0.6 microM of either NH4 or NO3 is the half saturation constant for majority of phytoplankton, but in one of those papers you have a nice table for different species. Km is probably even more than enough for survival, but it is considered close to the level for claiming the limitation.
