The purpose of the present study is to critically analyze the recent literature covering the production of inulinase enzyme from various sources by solid-state fermentation and discuss various approaches to increase its production in solid-state fermentation, purification, and its properties. The review deals with the solid-state fermentative production of inulinase production. Inulinases have many applications in industries, such as for the production of ultra-high fructose syrup, biofuels, lactic acid, citric acid, and single-cell oil. Solid-state fermentation (SSF) is more economic, requires smaller vessels, lowers water intake, reduces wastewater treatments, higher product yield, lesser chance of bacterial contamination, and lowers energy consumption. Furthermore, the crude products obtained from SSF can be directly used as the source of enzyme for biotransformation. Although many reports are available on a wide range of microbes which produces inulinases by SSF, it is important to isolate novel microbes for its production. Also, extensive research is going on to exploit unexplored sources for SSF. Higher yield of inulinases can be achieved by bioreactor modeling and proper monitoring of physical and chemical parameters in SSF.
