Hence, this study was conducted as to investigate the feasibility of rice husk alone without additional supplements as the SSF substrate to produce amylase from the local fungal isolate. Different microbial strains or isolate with different fermentation substrates may have different SSF process requirement for achieving high enzyme activity yield. Therefore, the SSF parameters such as initial  moisture  content  of  the  substrate,  incubation  period,  incubation  temperature  and  substrate particle were studied and optimised. The highest amylase enzyme activity was observed at 70 % of initial moisture content, 144 hours (6 days) and 30\u00b0C, with substrate particle size of 2 mm. Starch hydrolysis analysis performed indicated that the strength of amylase activity in the partially purified extracted enzyme was three times higher than the crude enzyme. Furthermore, a negligible or none of major aflatoxin compounds was detected in the crude and partially purified enzyme. The obtained findings strongly suggest the high potential usage of rice husk alone as the substrate in the SSF process for the production of aflatoxin-free amylase by the local isolate Aspergillus flavus (A. flavus) NSH9.<\/p>\r\n        \r\n                    <p><strong>Keywords:<\/strong>\r\n                aflatoxin, amylase, Aspergillus flavus, rice husks, solid-state fermentation            <\/p>\r\n            <\/div>\r\n\t\r\n\t\r\n\t\r\n\t<div class=\"asmsj-citation-box\">\r\n        <h3>How to Cite<\/h3>\r\n        <p id=\"citation-text\">\r\n            2025.
