Silk is made up of two types of proteinssilk fibroin and sericin. Silk sericin is the main residue (≈2030%) in raw silk fiber. It is composed of 18 amino acids. Solubility, molecular weight, and gelling properties of sericin depends on the methods of isolation i.e. degumming. Sericin has proved itself as a highly potential biomaterial by wide variety of applications in medicine, pharmaceuticals...

Increasing industrialization in developing country like India leading difficulty in pollution control. One of the major causes of pollution in aquatic ecosystem is discharge of heavy metals. Wastewater containing heavy metals are treated with conventional technology like chemical precipitation, ion exchange etc. Biosorption of heavy metals from aqueous solution can be considered as an alternati...

environmental contamination by toxic metals is a serious problem due to their extreme toxicity towards aquatic life and humans. biosorption is an alternative technology to conventional processes for the removal of metals. biosorption of pb(ii) ions on the lichen biomass of cladonia rangiformis hoffm. is presented in this research. batch experiments were conducted to study the biosorption prope...
