| Abstract: | Out of 45 actinomycetes isolated from garden soil, pond water and air;
fifteen showed good emulsification activity. Streptomyces sp. S22 isolated from garden soil produced maximum
bioemulsifier with 0.5% (v/v) sunflower oil during stationary phase at 37°C, pH 6 and 250 rev/min. Emulsification
activity was maximum (320 EU/ml) with sunflower oil as substrate. Partially
purified bioemulsifier from Streptomyces
sp. S22 was a peptidoglycolipid containing lipid (51.25%), protein (30%),
non-reducing sugar (17.75%) and reducing sugar (1%). The yield of partially
purified bioemulsifier was
1.6 g/l and reduced the surface tension of water by 23.09 mN/m. The
bioemulsifier produced by Streptomyces
sp. S22 was stable at room temperature for seven days. |
