Figure 1From: Bacterial bioaugmentation for improving methane and hydrogen production from microalgaeMethane and hydrogen production from C. vulgaris biomass. (a) cumulative methane yield in Series 1; (b) cumulative methane yield in Series 2; (c) accumulated hydrogen yield in Series 1; (d) accumulated hydrogen yield in Series 2, where inoculum ratios of C. thermocellum were 0% (●), 1%(○), 5%(▼), 10%(△) and (■) for one-step experiment, (□) for two-step experiment. Error bar represents the data range of duplicate test.Back to article page
