An essential initial step in converting biomass into useful chemicals is pretreatment of lignocellulosic materials (LM). There are numerous pretreatment techniques available in the literature, each having with its own advantages and disadvantages. The LM in this investigation were pretreated using surfactant foam. These lignocellulosic materials should be processed to boost the enzymatic action, enlarging the substrate’s pores and increasing its surface area, before being fed to a solid-state fermenter (SSF). Maximum lignin removal can be achieved with minimal effort by using surfactant foam. Comparative analysis was done if LM pretreated with and without foam bed column (FBC). The protein content was measured with the Kjeldahl method and porosity of the pretreated lignocellulosic material was check using scanning electron microscopy (SEM). The results of study have been explained based on the protein content and porosity of the material obtained after the surfactant foam treatment.
