Summary of external metabolite flux rates.

	µ (h−1)*	Glucose uptake (mmol g−1 h−1)	Ethanol (mmol g−1 h−1)	Glycerol* (mmol g−1 h−1)	Acetate* (mmol g−1 h−1)	Respiratory quotient
Control	0.26±0.03	12.55±1.47	20.52±2.58	0.53±0.17	0.16±0.06	4
Treated	0.17±0.02	15.40±1.52	19.65±2.85	2.17±0.29	0.89±0.11	2

Average growth and extracellular product secretion rates are shown for cultures treated with alpha-pheromone (treated) and without (control). All rates were calculated using data points after the addition of pheromone at 4.5 h, including in the control populations. Mean values of biological triplicates are presented with errors representing ±standard error. * denotes significant difference between control and pheromone treated groups (two sided students t-test with equal variance with p≤0.05).
