A new class of compounds, called as ionic liquids, has recently emerged as potential substitute for volatile organic solvents. Ionic liquids possess certain special physico-chemical characteristics that render them very useful in different areas of research and development. In this review, the physico-chemical properties and the applications of ionic liquids in chemical processes are critically...

abstract soil, is a reclamable and sustainable source. it is the basis of survival and it’s implication, should be performed on the basis of productivity identification according to scientific and technical rules, we can protect this valuable source, and increase it’s productivity and usage. nowdays, saline soils cover nearly 14.6% of the country area. study areas (kashan’ playa) have saline an...

CyanoPhyChe is a user friendly database that one can browse through for physico-chemical properties, structure and biochemical pathway information of cyanobacterial proteins. We downloaded all the protein sequences from the cyanobacterial genome database for calculating the physico-chemical properties, such as molecular weight, net charge of protein, isoelectric point, molar extinction coeffici...

Physico-chemical properties of Aspergillus conidia rely on their outer cell-wall rodlet layer. In A. fumigatus and A. nidulans, the rodlet structure is due to an hydrophobin encoded by homologous rodA genes. To evaluate the role of the rodlet structure on the physico-chemical properties of conidia, we compared hydrophobicity, Lewis acid-base (i.e. electron donor/acceptor) characteristics and el...

A series of O56-substituted carboxyester or carboxyamide derivatives of deglucoteicoplanin (TD) was prepared by condensation of the 56-hydroxyl function with various alkylating agents of general formula RBr, where R represents functional groups with different physico-chemical properties. The modifications at position 56 influenced the antimicrobial activity of the new derivatives; activity depe...

Pyocyanin is an electrochemically active metabolite produced by the human pathogen Pseudomonas aeruginosa. It is a recognized virulence factor and is involved in a variety of significant biological activities including gene expression, maintaining fitness of bacterial cells and biofilm formation. It is also recognized as an electron shuttle for bacterial respiration and as an antibacterial and ...
