TABLE 1.

Proximal composition of BSG before and after the SSF by A. ibericus in 500-ml cotton-plugged Erlenmeyer flasks followed by aqueous extraction (mean ± standard deviation) ^* and percentage of mass variation of each component.

Compound (% w/w dry basis)	Unfermented BSG	BSG_EF	Mass variation (%)
Protein	25.30 ± 0.02^a	29.31 ± 0.31^b	25
Fiber	59.94 ± 2.01^b	43.30 ± 0.30^a	53
Cellulose	21.16 ± 0.99^b	14.73 ± 0.39^a	55
Hemicellulose	23.77 ± 1.4^b	15.29 ± 0.2^a	58
Lignin	15.01 ± 0.41^a	13.28 ± 0.72^a	42

$% Mass variation = \frac{({(%w / w)}_{unfermented} x 10 g - {(%w / w)}_{fermented} x 6.45 g)}{{(%w / w)}_{unfermented} x 10 g}$ .

Means in the same row and different superscript letters are significantly different (Tukey's test, p<0.05).
