Enhanced Versatile Peroxidase Production by Pleurotus eryngii Using Saccharide- and Fatty Acid-Rich Agro-Industrial Waste in Solid-State Fermentation

Solid-state fermentation (SSF) of rice bran (RB) employing the edible fungus Pleurotus sapidus was investigated as a process strategy to improve the nutritional quality of this low-cost and abundant substrate. During fermentation, samples were withdrawn at different time intervals (4, 6, and 10 days) and further analyzed. Established methods were deployed to monitor the changes in nutritional composition (carbohydrates, proteins, ash, and lipids). Additionally, changes in fatty acid composition was studied as a function of culture progress. Results showed that the SSF of rice bran increased total carbohydrates from 36.6% to 50.2%, total proteins from 7.4% to 12.8%, and ash from 7.6% to 11.5%. However, the total lipid content was reduced from 48.5% to 27.8%. The fatty acid (FA) composition of RB included mainly oleic, linoleic, and palmitic acids. Upon fermentation with P. sapidus, small differences were found: linoleic acid and oleic acid content were increased by 0.4% and 1.1%, respectively, while palmitic acid content was reduced by 0.8%. This study demonstrated an improvement in the nutritional quality of RB after fermentation with P. sapidus, since protein, carbohydrates, minerals, and specific FA components were increased. As a whole, our results indicate that fermented rice bran could be used as a high-quality animal feed supplement.

Penelitian dilakukan untuk mengetahui pengaruh pemberian Aspergillus niger iradiasi sinar gamma dosis rendah pada jerami padi fermentasi dan potensinya sebagai pakan ternak ruminansia secara in vitro. Proses fermentasi dilakukan dengan teknik Solid State Fermentation (SSF) menggunakan A. niger yang diiradiasi sinar gamma dosis rendah untuk meningkatkan kemampuan memecah ikatan selulosa. Orientasi dosis iradiasi sinar gamma sebesar 0, 125, 250, 375, 500, 625 dan 750 Gy dilakukan pada A. niger untuk mengetahui kondisi yang optimum dalam menghasilkan aktivitas enzim selulase. A. niger iradiasi sinar gamma pada dosis yang optimum digunakan untuk pembuatan jerami padi fermentasi dan dilakukan evaluasi kemampuan jerami padi fermentasi sebagai pakan ternak ruminansia secara in vitro. Perlakuan jerami padi fermentasi yaitu P0. Jerami Padi, P1. Jerami padi fermentasi A. niger 0 Gy dan P2. Jerami padi fermentasi A. niger 500 Gy. Hasil menunjukkan bahwa dosis optimum iradiasi sinar gamma pada A. niger dalam menghasilkan enzim selulase (3,24 U/ml) adalah 500 Gy. Pada jerami padi fermentasi A. niger 500 Gy menunjukkan aktivitas enzim selulase tertinggi yaitu sebesar 48,5384 U/g bahan kering (BK) dan kadar glukosa sebesar 247,33 mg/g BK pada hari ke-14. Proses fermentasi dengan A. niger iradiasi sinar gamma (500 Gy) mampu meningkatkan kandungan proein kasar, acid detergent fiber (ADF), neutral detergent fiber (NDF) dan bahan kering, namun menurunkan kandungan lemak kasar dan bahan organik (BO). Hasil fermentasi dalam cairan rumen dari jerami padi fermentasi dengan dengan A. niger iradiasi sinar gamma (500 Gy) menunjukkan nilai pH sebesar 7,01; konsentrasi ammonia dan volatile fatty acid (VFA) masing-masing sebesar 3,92% dan 4,73 mmol/100.
