Diatoms are believed to contain essential mechanisms to perform both phototrophic and heterotrophic growth especially under light limited conditions [ 51 ].
WebWe examined the response of diatoms to naturally experienced temperatures and tested these hypotheses: (1) diatoms follow the rule that organism size decreases with increasing temperature; (2) diatom growth rate follows a Q 10-like response; (3) diatom carbon (C) and nitrogen (N) content per unit volume (V) decrease with increasing WebWhen faced with episodic N inputs, diatoms have evolved rapid nitrate uptake and storage strategies [16,17] and are able to efficiently adjust intracellular N turnover, C metabolism, …
