a bacterial strain (designated as alcaligenes sp. ms-103) isolated from oil sample of the aghajari oilfield in the south of iran, was able to produce an effective extracellular lipopolysaccharide biosurfactant (1.2±0.05 g/l) on molasses as a sole carbon source. the highest surface tension reduction to level 20 mn/m was achieved by biosurfactant produced by cells grown on molasses under optimum ...
Backgrounds and Objectives: Reactive dyestuff has potential of toxicity, carcinogenesis and mutagenesis for mammals and aquatic organisms. The current physical and chemical methods such as adsorption, coagulation, precipitation, filtration and ... can been used for removing of dyestuff. Biological treatment which is effective and economic for decontamination of dyestuff wastewaters was preferre...
We report the enzymatic degradation mechanism of a solution-grown poly[(R)-3-hydroxybutyrate] (P(3HB)) single crystal with an extracellular polyhydroxybutyrate depolymerase purified from Alcaligenes faecalis T1 (PhaZAfa). The P(3HB) single crystals adsorbed on highly ordered pyrolytic graphite were incubated with a wild-type or a hydrolytic-activity-disrupted mutant of PhaZAfa, and morphologica...
