Whilst aacC4 LMM showed a trend towards treatment effect (F(4, 41) = 2.1, P = 0.1), it was clear that the most noticeable change was towards an increased abundance in 80 ppm (3.5 ± 4), which was significantly greater than RLC (1.4 ± 0.9), 0 ppm (0.9 ± 0.7) and 30 ppm (1.3 ± 1.5; P < 0.05 for all), although with rather similar levels to CLC (2.3 ± 2, P = 0.31).
