Multiple Factors Analysis (MFA) of 18 variables measured for the six strains (3 high and 3 low biomass-producing strains) growing on SM45, SM85, SM165, SM260 and SM385 media. (A) Map representing the individuals on the two first axes (explaining 68% of the total inertia). (B) Map representing the three types of variables on the two first axes: in red, the contribution of six nitrogen sources (selected as exhibiting the most variability) to residual nitrogen in the medium when 70% of YAN had been consumed; in green, the uptake rates of the nitrogen compounds evaluated by sigmoïd models; in blue, fermentative variables.
