Effect of initial nitrogen concentration on (A) dry weight, DW; (B) maximal rate of YAN consumption, r _YAN ; (C) time required to consume 50% YAN, T ₅₀ ; (D) final amount of CO ₂ released, CO _2F ; (E) maximal rate of CO ₂ release, r _CO2max ; and (F) yield of biomass production with respect to consumed YAN, Y _DW/YAN . Low biomass-producing strains are shown by white bars and high biomass producing strains are shown by black bars. Mean values and standard error of the mean (SEM) were calculated from two replicates. The SEM is indicated by vertical error bars. The results of comparisons between the types of strain in each media are indicated inside the barplot^a. Comparisons were corrected for multiplicity testing by the Hochberg method. ^a: *, significant at p-value < 0.05, **, significant at p-value < 0.01.
