Abstract
Bioconversion of H2S into elemental sulfur has been investigated using an airlift bioreactor with
direct injection of the gas into the bioreactor. Almost complete removal of H2S has been achieved at
its inlet concentrations lower than 25 000 ppm. Maximum bioconversion capacity of ca 111.3 g/(m3路h)
and up to 93.5% conversion of the inlet sulfide to elemental sulfur was obtained. To further improve
the bioreactor performance, factors influencing mass transfer and biological activity should be investigated
in future studies
