“…The bacteria were cultured in 250 mL Erlenmeyer flasks containing 150 mL of different media in triplicate at 35°C in an incubator and shake at 150 rpm (Andualem & Gessesse, 2013). Bacterial growth measurement was done by measuring the cell concentrations (optical density (OD)) of E. coli and S. aureus in each medium at a wavelength of 600 nm by using a spectrophotometer (Shirahigue et al, 2018).…”

“…Peptone is a hydrolyzed product rich in amino acids that is uncoagulated at high temperatures (Shirahigue et al, 2018). According to the Global Peptone Market Report (2019), the global market of peptone reached USD 262.0 million in 2014 and slightly increased by approximately USD 271.0 million in 2019.…”

“…Several research studies have explored whether peptone extracted from fish by-products could improve the microbial growth rate and biomass production. Shirahigue et al (2018) reported that peptones extracted from tilapia (Oreochromis niloticus) and cobia (Rachycentron canadum) waste with different acid combinations significantly improved the growth rate and biomass production of Escherichia coli and Staphylococcus aureus cultures compared to commercial peptone. Moreover, Poernomo and Buckle (2002) reported that peptone isolated from cowtail ray (Trygon sephen) viscera was able to support the microbial growth rate of Bacillus subtilis, Escherichia coli, Staphylococcus aureus and Saccharomyces cerevisiae cultures.…”

Peptone is a hydrolysate product rich in amino acids, and it is uncoagulated at high temperature. Commercial peptone produced from land animals cannot be declared as acceptable in terms of lawfulness due to religious concerns. Catfish (Clarias gariepinus) and pangas catfish (Pangasius pangasius) are important species for the fish processing industry in Indonesia. The filleting process resulted in value by-products. The fish head as the by-products can be utilized as a main raw material for higher economic value products, such as peptone. The aim of this study was to characterize peptones extracted from the heads of catfish and pangas catfish with different acid conditions. The characteristics of chemical composition, yield, color parameter, solubility, amino acid content, bacterial growth rate and biomass production were observed. The catfish peptone (CFP) and pangas catfish peptone (PCP) obtained with different acid conditions showed high protein content in the range of 84.35% to 90.80% (P<0.05). The yields of CFP and PCP were significantly different (P<0.05) and varied between 4.75% and 5.66%. The solubility of treated peptones varied between 98.03% and 99.52%, and the peptones were rich in glycine, glutamic acid, proline and leucine. Bacterial growth test showed that both CFP and PCP had better growth rates compared to the commercial peptone tested in this study. In addition, the biomass production with peptone from catfish and pangas catfish was higher than that with the commercial product (P<0.05). This research proposed that catfish and pangas catfish heads could be developed as an alternative source for peptone production.
