Bioemulsifier production by Streptomyces sp. S22 isolated from garden soil.
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 degrees C, pH 6 and 250 rev/min. Emulsification activity was maximum (320 EU/ml) with sunflower oil as substrate. Partially purified bioemulsif...
متن کاملOptimization of Antibacterial Compounds Production by Aspergillus fumigatus Isolated from Sudanese Indigenous Soil
The purposes of the present study were to screen the ability of Aspergillus fumigatus to produce antibacterial compounds using different growth parameters namely, pH, temperature, agitation and time of fermentation and investigate the effect of the yield against bacterial isolates. A. fumigatus was isolated from arable lands in Sudan and identified macroscopically and microscopically. The pure ...
متن کاملOptimization of Cultural Parameters for Pigment Production from Streptomyces flavofuscus ARITM02, Isolated from Rhizosphere Soil
Actinomycetes are Gram-positive bacteria and they also known as a good source of microbial secondary metabolites producer in various pharma industries for therapeutic use. It is reported that many synthetic colors causes many serious problems related to environmental and it creates interest towards natural pigments from microorganisms. Natural pigments from actinomycetes are potentially good al...
متن کاملOptimization of the Production of Biosurfactant by Psuedomonas aeruginosa HR Isolated from an Iranian Southern Oil Well
In this study 152 bacterial strains were isolated from the contaminated oils in the southwest of Iran. Hemolysis was used as a criterion for the primary isolation of biosurfactant producing-bacteria. Fifty five strains had haemolytic activity , among them tweleve strains were good biosurfactant producers by measuring surface tension and emulsification activity.Two microorganism showe...
متن کاملDiversity of Biosurfactant-producing Streptomyces Isolates from Hydrocarbon-contaminated Soil
Actinomycetes are unsurpassed as producers of bioactive metabolites, primarily those with antimicrobial/anticancer properties; however, their capacity for producing other natural products such as biosurfactants, has been less explored. Biosurfactants are heterogeneous surface active compounds and can be potentially deployed for bioremediation of hydrocarbons and as emulsifying agents in agricul...
