Breakdown of SA production rate (r _SA ). Measured total rates are given by the red triangles with the empirical fit given by equation (3). The growth contribution to rate is given by the red curve - obtained from the product of the growth function (equation (2)) and Y_x,SA ^true (Figure4). The maintenance contribution to rate is given by the green curve - obtained by subtracting the growth contribution from the total rate.
