Özet

The effect of different calcium carbonate concentrations on butyric acid production with hydrogen production was investigated using cheese whey powder (CWP) as substrate (20 g/L). The study was carried out in dark fermentation using Clostridium acetobutylicum at 37°C for 10 days. As a result, 0.1 g/ L CaCO3 significantly increased both hydrogen production, butyric acid production potential, and BA/AA ratios. The values enhancing butyrate along with hydrogen were observed as 138.25 mL H2, 2.4 g/L butyric acid, 7.68 g/g BA/AA ratio, 0.17 g HBU/ g TS butyric acid production yield and 0.001 gHBU/ gTS h butyric acid production rate at 0.1 g/L calcium carbonate concentration.
