This research investigates a sustainable method for bioethanol synthesis from ammonia-pretreated rice straw utilizing a CaO/Ag nanocatalyst. The addition of ammonia elevated the available cellulose level of rice straw from 37.7% to 55.87%, thereby improving its suitability for enzymatic hydrolysis. The fungal isolate Aspergillus terreus (At PP590607) and the yeast Saccharomyces cerevisiae (Sc OR668931) were utilized both separ...
