Utilization of banana peel waste for citric acid production by Aspergillus niger

Abstract

Abstract The potential of Banana peel waste of Pisang Ayam (Musa acuminata), Pisang Raja (Musa Paradisiaca cv. Raja genom AAB), and Pisang Nipah (Musa balbisiana) as substrat for citric acid production by Aspergilus niger have been investigated. The main purpose of this research was to determine the percentages of citric acid production, pH, and total biomass at differences of media of banana peel waste. The results showed that the percentages of citric acid production using media of Musa acuminata, Musa Paradisiaca cv. Raja genom AAB and Musa balbisiana were 58.80, 69.84, and 46.80% respectively. The pH values of each media were 2.50, 1.50, and 2.0 respectively. The results also founded that the total biomass of each media were 2.442, 2.649, and 2.407 respectively. Overall, the results showed that banana peel waste of Musa Paradisiaca produce the highest amount of citric acid after 240 h fermentation.
