The agricultural industries generate lignocellulosic wastes that can be modified by fungi to generate high value-added products. The aim of this work was to analyze the efficiency of the bioconversion of sugarcane bagasse and cassava bagasse using two cheap home-made enzymatic cocktails from Aspergillus niger LBM 134 (produced also from agroindustrial wastes) and compare the hydrolysis yield with that obtained from the bioconversion using commercial enzymes. Sugarcane bagasse and cassava bagasse were pretreated with a soft alkaline solution before the hydrolysis carried out with home-made enzymatic cocktails of A. niger LBM 134 and with commercial enzymes to compare their performances. Mono and polysaccharides were analyzed before and after the bioconversion of both bagasses as well as their microscopic structure. The maximal yield was the 80% of total glucans saccharified from cassava bagasse. The bioconversion of both bagasses were better when we used the home-made enzymatic cocktails than commercial enzymes. We obtained high added-value products from agroindustrial wastes, home-made enzymatic cocktails and hydrolysates rich in fermentable sugars. The importance of this work lays in the higher performance of the cheap home-made enzymatic cocktails over the hydrolytic performance of commercial enzymes due to the cost of producing the home-made enzymatic cocktails were more than 500 times lower than commercial enzymes.
