Assessment of Antioxidant and Antibacterial Activities of Pokea Clam (Batissa violacea celebensis) Protein Hydrolysates: An in vitro Approach
Abstract
The pokea clam (Batissa violacea celebencis Martens, 1897), a freshwater bivalve of the Corbiculidae family, is indigenous to the Pohara River in Konawe, Southeast Sulawesi. Recognised as an endemic species, it has been traditionally utilised by local populations for the treatment of ailments such as jaundice, malaria, asthma, high blood pressure, and fever. Marine-derived bioactive peptides, especially from bivalves, can be extracted via enzymatic hydrolysis, producing protein hydrolysates known for their potential in functional food applications. These hydrolysates possess notable health-promoting properties, including antioxidant and antibacterial effects, which may offer advantages over synthetic alternatives. In this study, the antioxidant capacity of pokea clam protein hydrolysates was analysed using DPPH and ABTS methods, resulting in IC₅₀ values of 52.304 mg/mL and 81.268 mg/mL, respectively. Antibacterial testing via the agar diffusion technique demonstrated strong inhibitory effects against Staphylococcus aureus, Salmonella typhi, and Escherichia coli, with respective inhibition zone diameters of 28 mm, 23 mm, and 18.5 mm. These findings underscore the potential of pokea clam protein hydrolysates as therapeutic agents for oxidative stress and bacterial infections.
