The surfactant tween 80 enhances biodesulfurization.
In biocatalytic conversions, substrates and products may display inhibitory or toxic effects on the biocatalyst. Rhodococcus erythropolis 1awq could further remove sulfur from hydrodesulfurized diesel oil, and the biodesulfurization was enhanced by the surfactant Tween 80. Tween 80 was shown to decrease the product concentration associated with the cells, reducing product inhibition.
متن کاملAerosol delivery of synthetic lung surfactant
Background. Nasal continuous positive airway pressure (nCPAP) is a widely accepted technique of non-invasive respiratory support in premature infants with respiratory distress syndrome due to lack of lung surfactant. If this approach fails, the next step is often intubation, mechanical ventilation (MV) and intratracheal instillation of clinical lung surfactant. Objective. To investigate whether...
متن کاملEnhanced Chrysene Biodegradation in Presence of a Synthetic Surfactant
To degrade chrysene, a polycyclic aromatic hydrocarbon (PAH) found in crude oil contaminated soil by bioremediation the Polyporus sp. S133, a fungus collected from soil was used. Maximal degradation (86%) was obtained when Polyporus sp. S133 was incubated in 0.5% tween 80 for 30 days, as compared to 30% degradation rate without tween 80. Chrysene was indeed degraded by Polyporus sp. S133 throug...
متن کاملComparison of three lipid formulations for synthetic surfactant with a surfactant protein B analog.
Surfactant protein B (SP-B) is an essential component of pulmonary surfactant. Synthetic dimeric SP-B(1-25) (SP-B(1-25)), a peptide based on the N-terminal domain of human SP-B, efficiently mimics the functional properties of SP-B. The authors investigated the optimum lipid composition for SP-B(1-25) by comparing the effects of natural lung lavage lipids (NLL), a synthetic equivalent of NLL (sy...
متن کاملSurfactant (Genapol OX-80) toxicity to Selenastrum capricornutum.
A non-ionic surfactant (Genapol OX-80) was proposed as a means of reducing destructive crayfish activity in rice. In order to study the toxicity of this product on algae, a test in accordance to the ISO 8692 protocol (1989) was performed. The growth inhibiting effect of the pure formulation of Genapol OX-80 was studied on Selenastrum capricornutum in the concentration range of 0.01-1.0 mg/l. Th...
