Fig. 5From: Application of a novel biological-nanoparticle pretreatment to Oscillatoria acuminata biomass and coculture dark fermentation for improving hydrogen productionEffect of Mg-Zn Fe2O4-NPs for cellulolytic activity produced by T. harzianum Ps-2 using solid-state fermentation (SSF). All data represented means of 3 replicas ± standard deviation (SD). Different capital letters in each plotted series indicate significant differences at p ≤ 0.05 using Duncan's testBack to article page
