Butyric acid is produced from the petroleum derivative propylene by chemical route. It an important precursor in fuel, pharmaceutical, chemical, and food industries. However, due to demand for bio-based molecules, fermentative production of butyric renewable feedstocks has received growing attention. Worthy new applications make it outstanding precursor. This review thoroughly discusses steps produce lignocellulosic materials, including evaluating suitable biomass, presenting recurrent pretreatment fermentation strategies, then discussing factors related each step's productivity. The non-solventogenic most promising method producing acid. Currently, bioproduction data are at laboratory scale, butyrate titer productivity need improvements reach industrial viability.
