| Acetylcholinesterase (AChE) inhibitors are vital in the management of Alzheimer’s disease. This study aimed to identify bacteria isolated from sponge samples collected near Hengam Island and evaluate their acetylcholinesterase inhibitory activity. Sponge samples of Halicona sp. and Axinella sp. were collected by scuba diving. A total of 131 bacterial strains were isolated using Marine Zobell agar medium. Bacillus and Vibrio species were the most frequently identified bacteria from the sponge samples. Analysis of the extracted metabolites revealed that four isolates could inhibit acetylcholinesterase activity, with IC50 values between 203.60 and 385.62 μg/ml. According to the MTT cell proliferation assay, HH 151 extract exhibited cytotoxic effects on the HUVEC cell line. The AChE inhibitory extracts also showed DPPH radical scavenging activity between 78.12 μg/mL and 237.54 μg/mL. The 16S rRNA sequence analysis showed about 99 to 100% homology between HH 127, HH 151, HA 315, and HA 338 strains with Vibrio azureus, Streptomyces nigrescens, Bacillus pumilus, and Bacillus subtilis species. These findings provided new candidates of the acetylcholinesterase inhibitors from sponge-associated bacteria for in vivo studies. | ||
