Summary, etc. Present study evaluates the production and characterisation of biosurfactant for its antimicrobial, antioxidant, larvicidal and antitermite activities. A bacterium has been isolated from fatty acid contaminated soil and identified as biosurfactant producer , Gram positive <em>Bacillus subtilis </em>(MF582633) subspecies <em>inaquosorum</em> based on 16S rRNA sequencing and unique QR codes. The bacterium produced 2.03 g/L of biosurfactant using 3% glycerol as a carbon source. Among the tested five organisms <em>K.pneumoniae</em> revealed (20.3 mm) and <em>E coli</em> (10 mm) zone of inhibition as compared to standard antibiotic ampicillin (40 µg/mL ) when biosurfactant concentration is reported to be 40 µg/mL. Antioxidant activity in terms of IC<sub>50</sub> value at 0.4 mg/ mL is recorded. The 100% larvicidal activity is recorded at 50 mg/mL concentration of biosurfactant while 40 mg/mL concentration in 48 h revealed 100% antitermite activity. Biosurfactant is purified through silica gel column chromatography. Purified biosurfactant has been characterised using FTIR and <sup>1</sup>H NMR analysis and revealed surfactin type of lipopeptide biosurfactant. Experimental results may add its value in the development of antibiotics and biopesticides to stop the menace of UTI infections, <em>Culex</em> larvae and termites.
