These experiments were conducted in triplicate.
apH value was controlled at 5.0 with H2SO4.
bThe results of barely shochu wastewater (diluted twice) treated with repeated-batch cultivation previously reported (12) were shown for reference.
cSignificantly different barley to sweet potato (p < 0.05) by t-test.
