  "abstract": "Biosurfactants are eco-friendly surface-active compounds produced by microorganisms that lower surface and interfacial tensions, enhancing the bioavailability of hydrophobic compounds. The study reports the isolation and characterization of biosurfactant-producing bacteria from industrial waste effluent in a river near Dhaka, Bangladesh. Using diesel-enriched media, bacterial strains were isolated and screened for biosurfactant production using oil displacement, emulsification index (E24%), and drop-collapse assays. The microbial cultures were characterized based on biochemical activities and 16S rRNA sequencing. Biosurfactant characterization was carried out using chromatographic techniques. Six cultures passed the drop-collapse and oil-displacement tests with E24% ranging from 9% to 41%. The CTAB agar assay confirmed the anionic nature of the biosurfactants. The potential biosurfactant producers belong mostly to the Bacillus and Stutzerimonas groups, with one low-biosurfactant-producing isolate from the Enterobacteriaceae group. The presence of two consortia, Bacillus-Acinetobacter and Bacillus-Stutzerimonas, was also observed. The isolates and consortia exhibited varying levels of antibacterial, antifungal, adherence, and plant growth-promoting activity. Biosurfactant production capacity under extreme conditions has been characterized by pH stability (pH 2-pH 11), salinity tolerance (2%-10% NaCl), and temperature tolerance (40°C-100°C). Overall, they provide a green and economical alternative to synthetic surfactants, with low toxicity and potential applications in bioremediation, biocontrol, and plant growth promotion.",
