Levels of organic acids (g/L) obtained in BPL013 fermentations.

	Organic acids concentration (g/L)
	No pH control			pH control
	5 h	30 h	42 h	42 h
Lactic acid	0.479 ± 0.090	1.387 ± 0.096*	10.093 ± 0.088**	22.814 ± 0.397**
Acetic acid	0.060 ± 0.051	0.065 ± 0.051	0.084 ± 0.054	0.109 ± 0.064
Propionic acid	0.058 ± 0.041	0.045 ± 0.030	0.058 ± 0.027	0.058 ± 0.023

Succinic acid	0.092 ± 0.001	0.11 ± 0.002	0.104 ± 0.023	0.133 ± 0.032

LOQ, Limit of quantification = 0.01 g/L (lactic acid, succinic acid, propionic acid, butyric acid) and 0.05 g/L (acetic acid). Statistics are done comparing 5 h values vs. 22 and 45 h, respectively.

^*p-value < 0.01,
