Abstract:
... Enzymatically pre-treated sugarcane bagasse (SCB) was used as substrate for sequential production of hydrogen (H₂) and methane (CH₄). In stage I, SCB was used by autochthonous bacteria, such as Enterococcus (42.4 % relative abundance) and Paraclostridium (16.8 %) for H₂ production (166.8 mL H₂/L), while the metabolites accumulated at the end of this stage (9140.5 mg HAc/L) were used by allochthono ...
