Resumo(s): | In the present research effort, production of crude sericin extracts from Bombyx mori silk cocoons was attempted using two different approaches. Sericin was extracted from cocoons by high-temperature autoclaving followed either by lyophilization or freezing-thawing precipitation, to obtain a crude sericin powder. The physico-chemical and biological characteristics of the crude sericin extracts were evaluated in detail, via FTIR, XRD, XRF, XRT, UVvis scanning, TGA and DSC, protein quantification, antimicrobial activity, free radical scavenging activity, cytotoxic activity, potential for inducing chromosomal aberrations via Allium cepa assays, and genotoxicity via Comet analyses. The molecular weight distribution of the crude sericin extracts was also investigated, via sodium dodecyl sulfatepolyacrylamide gel electrophoresis (SDSPAGE), and the results duly compared to standard sericin. The results gathered clearly suggest that the crude sericin extracts had both obvious radical scavenging effects with the 2.2-diphenyl-1-picryl-hydrazil (DPPH) assay, and antibacterial activity, further suggesting that this protein might be a valuable addition for either food and biopharmaceutical applications. |
