| dc.description.abstract | Present study demonstrates the thermal and antimicrobial characterizations of Lac along with spectra and DC conductivity. Study reveals intact thermal stability of Lac irrespective to rate of heating. Lac was thermally degraded in single step at 10oCmin-1 with TG onset at 300oC.This was left with 8.28% residue. Degradation of Lac was concluded TG end set at 500oC leaving 8.83% residue. Thermo gram of Lac decomposed @ 20oCmin-1 thermo gram reveals not much significant shift in TG onset and TG end set temperatures. This attributes thermally stable nature of Lac irrespective to increasing heat of degradation. FT-IR spectra of Lac reveals the presence of characteristic functionalities supported with literature. σDC of Lac pellets was studied at three different voltages in the range of 1 to 100V at room temperature. σDC measurements revels increase in conductivity of Lac with voltage is 2.5 × 10-2 Scm-1. Lac did not exhibit any zone of inhibition against three test fungi : Aspergillus niger, Trichoderma asperellum, Penicillium chrysogenum at various concentrations using both the disc and well diffusion methods. | en_US |
