Utilization of sludge palm oil as a novel substrate for biosurfactant production by Wan Nawawi, Wan Mohd Fazli, Jamal, Parveen, Alam, Md. Zahangir

“…Potential strains of microorganism were isolated from various hydrocarbon-based sources at palm oil mill and screened for biosurfactant production with the help of drop collapse method and surface tension activity. Out of 22 isolates of microorganism, the strain S02 showed the highest bacterial growth with a surface tension of 36.2 mN/m and was therefore, selected as a potential biosurfactant producing microorganism. …”

Optimization of process conditions for biosurfactant production by Jamal, Parveen, Alam, Md. Zahangir, Wan Nawawi, Wan Mohd Fazli

“…Optimization of process conditions had led to reduction of surface tension from 41mN/m to 30.21mN/m. Further statistical optimization gave the lowest value of surface tension of 29.38mN/m at temperature = 340C, pH = 8, agitation = 250rpm, and inoculums size = 3.2 %( v/v).…”

Screening of biosurfactants from marine microorganisms by Al-Araji, Laith, Kadum, R. H. J

“…Ten bacterial strains previously isolated were selected for the screening of biosurfactant producer(s) via three different characterization tests for biosurfactant; (i) surface tension measurements, (ii) emulsification activity, and (iii) cetyltrimethylammonium bromide assay (CTAB) test. …”

Isolation and screening of bio-surfactant producing bacteria from degraded palm kernel cake under liquid state fermentation by Shajrat, Mir, Jamal, Parveen, Alam, Md. Zahangir

“…Potential bacterial strains were isolated from degraded palm kernel cake and screened for biosurfactant production with the help of drop collapse assay and by analyzing the surface tension activity. From the screened isolates, strain SM03 showed the best and consistent results and was therefore, selected as a potential biosurfactant producing microorganism. …”
