Abstract
The uses of proteolytic enzymes in manufacturing procedures are numerous. Researchers are investigating a number of strategies to find, rework, or artificially produce enzymes with improved suitability for manufacturing processes in light of the growing needs and uses. Alkaline protease production was assessed in fungal strains that were obtained from soil using the serial dilution technique. Using molecular techniques, the isolate with the greatest potential for producing enzymes was identified. Gel filtering was used to purify the enzyme. In order to enhance fugus ability to generate protease under various growth conditions, this investigation explains how to optimize a culture medium. The fungus with the highest probability was identified as Penicillium verrucosum with accession number PV529631. The purified homodimer protein for purified protease was assessed to have two peaks at 42.5 kDa and 83.7 kDa, consequently upon screening at 280 nm. The optimal culture conditions have been detected upon culture for the isolated fungus at pH =9, temperature = 35 °C, using sucrose as a carbon source, insertion of peptone as a nitrogen and using Soy cake as waste material for culture conditions. The results of the research demonstrate the P. verrucosum strain's capacity to produce the protease enzyme. To fully use the possibilities of these substrates and promote the creation of superior and effective hydrolytic enzymes, it is imperative to keep investigating and refining these approaches.
