Beschreibungen/Notizen

• Bioconversion of H sub(2) S into elemental sulfur has been investigated using an airlift bioreactor with direct injection of the gas into the bioreactor. Almost complete removal of H sub(2) S has been achieved at its inlet concentrations lower than 25 000 ppm. Maximum bioconversion capacity of ca 111.3 g/(m super(3) times 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.
