Evaluation of different pretreatments on organic matter solubilization and hydrogen fermentation of mixed microalgae consortia

Enhanced Biohydrogen Production from Citrus Wastewater Using Anaerobic Sludge Pretreated by an Electroporation Technique

“…This could be attributed to the complete degradation of the substrates. 47,48 The maximum hydrogen production was observed in the 1 min EP-pretreated inoculum, which suggests that a greater number of hydrogen-producing bacteria have survived while hydrogen consumers were inactivated. In contrast, the total gas production is the highest (Figure 3) for the untreated bacteria seed than for all other pretreated conditions because a greater number of cells and diverse types of microorganisms were present in untreated AS.…”

Evaluation of gradual adaptation of mixed microalgae consortia cultivation using textile wastewater via fed batch operation

“…Protein and carbohydrate accumulated indicated the quality of microalgae grown biomass alongside with remediation as well [ 19 ]. The accumulation of protein and carbohydrate are shown in Supplementary information.…”

“…It is one of the critical factors to prospect and select cost-effective growth/nutrient medium towards efficient growth of microalgae for the biofuel/biochemical generation along with the remediation of toxic/nutrient removal such as nitrogen and phosphorous [ 19 ]. Over the previous literature survey, Lee et al [ 18 ] reported that using semi-continuous reactor with livestock wastewater as growth medium achieved 0.2 g.L −1 .d −1 of biomass productivity where Yu and Kim et al (2017) sequencing batch reactor operated achieved 0.315 g.L −1 .d −1 as shown in Table 3 .…”

Surfactant induced sonic fission: an effective strategy for biohydrogen recovery from sea grass Syringodiumisoetifolium

“…For inoculum, anaerobically digested sludge was collected from a digester. To eliminate methanogenic microbes from collected sludge, it was heated for 30 minutes at 100°C as per the study of Kumar et al 21 The pH probes inside the reactors were adjusted to 5.5. To maintain the anaerobic environment in the reactors, N 2 gas was introduced into the reactor and sealed tightly with rubber stoppers.…”
