Production and spillage of petroleum hydrocarbons which is the most versatile energy resource causes disastrous environmental pollution. Elevated oil degrading performance from microorganisms is demanded for successful microbial remediation of those toxic pollutants. The employment of biosurfactant-producing and hydrocarbon-utilizing microbes enhances the effectiveness of bioremediation as bios...

An elastin-like polypeptide (ELP) composed of a polyhistidine tail (ELPH12) was exploited as a tunable, metal-binding biopolymer with high affinity toward cadmium. By taking advantage of the property of ELPH12 to undergo a reversible thermal precipitation, easy recovery of the sequestered cadmium from contaminated water was demonstrated as the result of a simple temperature change. In this stud...

A number of Pseudomonas strains function as inoculants for biocontrol, biofertilization, and phytostimulation, avoiding the use of pesticides and chemical fertilizers. Here, we present a new metabolically versatile plant growth-promoting rhizobacterium, Pseudomonas rhizophila S211, isolated from a pesticide contaminated artichoke field that shows biofertilization, biocontrol and bioremediation ...

Bonchev St., Block 26, 1113 Sofia, Bulgaria e-mail: [email protected]; ABSTRACT The resistance of bacteria to antibiotics is a serious public problem with increasing significance. The development of novel pharmaceuticals with wide spectrum...

Palm fatty acid distillate (PFAD) and methyl ester (FAME) are used by P. aeruginosa PAO1 to produce rhamnolipid biosurfactant. The process of fermentation producing biosurfactant was structured in a 2 L bioreactor using 2% PFAD FAME as carbon sources minimal medium with nitrogen concentration 1 g L?1. Mass spectrometry results show the crude produced predominantly monorhamnolipid (Rha-C10-C10) ...

The results of studies the synthesis AgNPs colloidal solutions by cyclic voltammetry (E from +1.0 to −1.0 V) in rhamnolipid (RL) and use soluble anodes ultrasound field (22 kHz) are presented. It is shown that algorithm anodic dissolution—reduction Ag(I)—nucleation, formation makes it possible obtain nanoparticles with size 1 nm 3 nm. was found an increase RL concentration g/L 4 g/L, cathodic c...
