  1. The amount of individual sugars present in the AE in mg/mL before (−Rh.mucilaginosa) and after (+Rh. mucilaginosa) Rh. mucilaginosa growth. Among columns of AE concentrations or Alperujo water. Each value was compared against the corresponding one in –Rh. sp. condition * Denotes statistically significant differences p < 0.01. n = 3
