Table 3.
Analysis of variance for three metabolic traits: the yield of the fermentation process (Yferm), the maximal quantity of ethanol produced in the medium (Ethmax), and the specific glucose consumption rate when 50% of the glucose was consumed (Jspec).

Block and Strain are main random effects while medium (1 and 15% glucose) and habitat of origin (ori: forest, industrial, clinical, fruit and laboratory) are main fixed effects.
