Abstract: | Summary To satisfy the demand for simple production technology (simple and cheap reactor, cheap recovery and finishing), solid state cultivations were carried out with pretreated straw in a simple fixed bed reactor under nonsterile conditions.The results of these investigations were compared with those evaluated in a stirred tank reactor. The same cell mass fractions were obtained in both reactors. However, about double the cultivation time is necessary for a solid state cultivation as compared to a submerse cultivation.Symbols N2
