Odor production and profile characteristics in fermentation broth. a The production of H2S from fermentation. b The production of NH3 from fermentation. c The concentration of soluble sulfide (S2−) in fermentation broth. d The concentration of VFAs in fermentation broth. Error bars show one standard deviation, and the mean value was calculated from six replicates. The mean value is labeled above the error bars with different superscripts indicating a significant difference (P < 0.05). Hn: Hy-Line, Ln: Lohmann
