Fig. 2From: Enhanced short chain fatty acids production from waste activated sludge conditioning with typical agricultural residues: carbon source composition regulates community functionsSCFAs production performance of batch WAS fermentation tests. The variation of SCFAs concentrations during the fermentation time in group CSS, RSS, LESS, ABSS, and BLS in batch WAS fermentation tests are shown in this figure. Linear fit analysis was applied; formula and correlation coefficient of each line are portrayed in the figureBack to article page
