Antibacterial Activity of Endophytic Bacterial Extracts Isolated from Pineapple Peel (Ananas comosus L.)

Endophytic bacteria are known to contain various bioactive substances. Pineapple peel (Ananas comosus L.) is a waste product utilized in environmental preservation. The present study focused on the isolation of endophytic from pineapple peel, and assessment their antibacterial activity. ethyl acetate extracts isolated were tested for activity using disc diffusion method. components bacterial extract identified by UPLC-MS/MS analysis. Extract (Bacillus velezensis WSM-1) had highest with an inhibition zone diameter 17.71 mm 15.87 against Staphylococcus aureus Escherichia coli, respectively. UPLC MS/MS analysis several compounds, including; 6-Methoxyquinoline, 2-(6-amino-9H-purin-9-yl)-5- (hydroxymethyl)oxolane-3,4-diol, Aklavin, Maltotriose, Cholestanetriol, Piperic acid, Isoflavone, Paromomycin, Mycaloide B. Paromomycin have It type antibiotic that belongs aminoglycoside class commonly used treat infections caused gram-negative bacteria. results suggest isolate potential there need further characterize active constituents.&nbsp
