In SSF, the bioreactor provides suitable environment for microorganism growth and biological activity. Bioreactors must be able to hold the media and be sealed well which prevents harmful environment substances entering in to the bioreactor. Important parameters in bioreactor design include temperature, oxygen concentration, moisture gradients as well as mixing/agitation, aeration and heat transfer. SSF bioreactor design can be classified into four groups, which can be separated by aeration and mixing type: | In SSF, the bioreactor provides suitable environment for microorganism growth and biological activity.
