Influence of seed sludge and pretreatment method on hydrogen production in packed-bed anaerobic reactors
Abstract Several studies have reported on the effects of inoculums source and pretreatment on biological hydrogen production. However, there have been few studies on continuous reactors. This paperExpand
Organic loading rate impact on biohydrogen production and microbial communities at anaerobic fluidized thermophilic bed reactors treating sugarcane stillage.
It was obtained, for H2 yield and content, a decreasing trend by increasing the OLR, and among the organic acids obtained, there was a predominance of lactic acid and butyric acid. Expand
Hydrogen production from cheese whey with ethanol-type fermentation: effect of hydraulic retention time on the microbial community composition.
The effects of different hydraulic retention times (HRTs) and varying sources of inoculum (sludge from swine and sludge from poultry) on the hydrogen production in two anaerobic fluidized bed reactors (AFBRs) were evaluated and indicated that the microbial community were affiliated with the genera Selenomonas sp.

Hydrogen production from diluted and raw sugarcane vinasse under thermophilic anaerobic conditions
Abstract Two continuous anaerobic fluidized bed reactors (AFBRs) were operated under thermophilic (55 °C) temperature for 150 days to investigate the effect of dark H 2 fermentation of diluted andExpand
Performance evaluation and phylogenetic characterization of anaerobic fluidized bed reactors using ground tire and pet as support materials for biohydrogen production.
This study evaluated two different support materials (ground tire and polyethylene terephthalate [PET]) for biohydrogen production in an anaerobic fluidized bed reactor (AFBR) treating syntheticExpand
Performance of a reactor containing denitrifying immobilized biomass in removing ethanol and aromatic hydrocarbons (BTEX) in a short operating period.
The independent removal of each hydrocarbon demonstrated that these contaminants can be biodegraded separately, without the need for a compound to be the primary substrate for the degradation of another. Expand
Effect of Daily Consumption of Orange Juice on the Levels of Blood Glucose, Lipids, and Gut Microbiota Metabolites: Controlled Clinical Trials.
It is suggested that a daily consumption of orange had a positive effect on the intestinal microbiota and metabolic biomarkers of young women, which may be an effective alternative for a healthy drink. Expand
Lactobacillus acidophilus CRL 1014 improved “gut health” in the SHIME® reactor
This study showed the beneficial influence of L. acidophilus CRL 1014 on microbial metabolism and lactobacilli community composition for improving human health. Expand
Microbial characterization and removal of anionic surfactant in an expanded granular sludge bed reactor.
This study evaluated linear alkylbenzene sulfonate removal in an expanded granular sludge bed reactor with hydraulic retention times of 26 h and 32 h to determine the total anaerobic bacteria and methanogenic Archaea. Expand
Impact of multi-functional fermented goat milk beverage on gut microbiota in a dynamic colon model.
The results demonstrated that the multifunctional beverages formulated, with or without grape pomace extract, exhibited high dietary fiber, oleic acid, phenolic compounds content and antioxidant activity, and can offer a new perspective for the production of foods with positive potential effects on human health.
