Abstract Agro processing industry generates substantial quantities of waste materials which cause serious environmental pollution throughout the year. Solid state fermentation (SSF) process offers great potential to utilize these waste materials to manufacture several important products such as enzymes, organic acids, alcohols, pigments, gums, aroma compounds, biopesticides, surfactants, vitamins etc. on commercial scale. Most important feature of SSF over submerged fermentation (SmF) is that crude fermented products may be used directly or after partial purification. An attempt has been made to present information on production of various enzymes, biopesticides, surfactants, vitamins as well as other products such as pigments, gums, alcohol, aroma compounds, etc. by SSF process.
