Abstract
In the present research experiment we have used local & chiefly available four different waste-going agro-residues such as Rice bran, Wheat Bran, Bagasse, & Orange peel were collected from agriculture fields and powdered to obtain a particle size of 1.0 to 2.0 mm. SSF was performed with all the four substrates by a fungus, Aspergillus niger to observe potenial production of an extracellular enzyme, Beta –fructofuranosidase under the influence of various factors. Among all selected agro-residues, the rice bran with tap water was found most suitable substrate for higher production of enzymes under the fixed optimized conditions of 120 hours of incubation, 1000 µl of moisture level, 5^th day culture of inoculum age, and at 35 0C of temperature.
