Fig. 10From: Application of a novel biological-nanoparticle pretreatment to Oscillatoria acuminata biomass and coculture dark fermentation for improving hydrogen productionCumulative biohydrogen production after 48 h from K. pneumoniae, E. cloacae and their coculture using different hydrolysates of O. acuminata compared to glucose standard. Each value represents the mean value of three independent replicates. Different capital letters in each plotted series indicate significant differences at p ≤ 0.05 using Duncan's testBack to article page
