AB  - Carbon materials are promising in improving the performance of anaerobic 
      digestion, however, interactive mechanisms between the carbon-based enhancement 
      and operating parameters remained unclear. Using anaerobic digested sludge as 
      inoculum, the effects of Taihu blue algae biochar (ABC) on methanogenesis at 
      different inoculation ratios were investigated during sludge anaerobic digestion. 
      Results showed that ABC enhanced methane productions at the lower inoculation 
      ratios (4% and 1%, v/v), but not at the higher ratio (10%, v/v). Mechanism 
      analysis demonstrated methanogenic improvements at the lower inoculation ratios 
      were not owing to initial organic loading rate increments. Otherwise, ABC 
      addition at the lower inoculation ratios were more favorable for the enrichment 
      of Methanosarcina than the higher ratio, which might be benefit for 
      methanogenesis through directed interspecies electron transfer. Thus, for the 
      improvement of sludge anaerobic digestion, the microbial enrichments at different 
      inoculation ratios would be more important than the merely biochar addition.
