Title
Immobilized Biofilm in Thermophilic Biohydrogen Production using Synthetic versus Biological Materials
Abstract
Biohydrogen production was studied from the vermicelli processing wastewater using synthetic and biological
materials as immobilizing substrate employing a mixed culture in a batch reactor operated at the initial pH 6.0 and
thermophilic condition (55 ± 1ºC). Maximum cumulative hydrogen production (1,210 mL H2/L wastewater) was
observed at 5% (v/v) addition of ring-shaped synthetic material, which was the ring-shaped hydrophobic acrylic.
Regarding 5% (v/v) addition of synthetic and biological materials, the maximum cumulative hydrogen production
using immobilizing synthetic material of ball-shaped hydrophobic polyethylene (HBPE) (1,256.5 mL H2/L
wastewater) was a two-fold increase of cumulative hydrogen production when compared to its production using
immobilizing biological material of rope-shaped hydrophilic ramie (609.8 mL H2/L wastewater). SEM observation
of immobilized biofilm on a ball-shaped HBPE or a rope-shaped hydrophilic ramie was the rod shape and gathered
into group.
