Biological hydrogen production (biohydrogen) is promising due to its renewable nature. Photofermentative
biological hydrogen is realized by purple non-sulfur bacteria (PNSB), using various organic substrates such as
volatile fatty acids. PNSB can be immobilized to increase their concentrations and enhance their stability. Under
appropriate conditions, biofilms may appear as a special and effective form of bacteria immobilization. In the
present study, the PNSB species Rhodobacter capsulatus was used for hydrogen production in a biofilm
photobioreactor. In the study, an electrostatic flocking technique was used to produce polyamide flock microfibers
and the flocks were attached to support to create immobilization matrices. Results revealed that it was possible to
immobilize R. capsulatus cells both on functionalized and non-functional microfiber flocks. R. capsulatus biofilm
development was followed by the production of biohydrogen for 14 days.
