    • The study for the production of protease from Aspergillus flavus using wheat bran as substrate under Solid State Fermentation was conducted in University of Abuja, Department of Microbiology. Aspergillus flavus was isolated from spoilt bread and was identified on the basis of the morphological assessment such as macroscopic and microscopy. Among the characteristics used includes: colonial characteristics such surface appearance, texture and colour of the colonies. The protease activity increased with increase in the fermentation periods. The quantities of the protease enzyme produced by the Aspergillus flavus in the basal medium were measured using UV-Spectrophotometer and the result is shown in Table 5. The protease activity was found to be higher at day 7 than day 5 and 3 with 4.51±10.06 proteaase Unit/mL, 8.63±0.12 U/mL and 18.93±1.20 AU/mL respectively. the extracellular protease produced by Aspergillus flavus isolated from spoilt bread in Gwagwalada were not significantly different at P= 0.05 level of significance. The study demonstrated thatAspergillus flavus wasable to produce extracellular protease enzymes important in the decomposition of protein materials.

Proteases are (physiologically) necessary for  living organisms; they are ubiquitous and found in a wide diversity of sources. Protease is the most important industrial enzyme of interest accounting for about 60% of the total enzyme market in the world  and  account  for approximately 40% of ... Continue reading---
