(a) Relationship between 𝛼 𝐵 calculated from gross photosynthesis versus light intensity curves (P/E in Figure 1) and Chl a/Chl c ratio (Table 1) in Amphora coffeaeformis, Amphora acutiuscula, Entomoneis paludosa, and Nitzschia palea grown in ASW in the absence (□) or the presence () of Zn supplementation. (b) Relationship between the total Chl content (Table 1) and the maximum gross photosynthesis ( 𝑃 𝐵 m a x ) (Figure 1) in Amphora coffeaeformis, Amphora acutiuscula, Entomoneis paludosa, and Nitzschia palea grown in ASW in the absence (■) or the presence () of Zn supplementation.
