Activity of catalyst remains unaffected on continuous use. <br/> <br/>Page(s): 730-734 http://nopr.niscair.res.in/handle/123456789/5305 Title: Evaluation of selected biomass for charcoal production <br/> <br/>Authors: Sugumaran, P; Seshadri, S <br/> <br/>Abstract: <i>Casuarina equisetifolia</i> L. and <i>Lantana camara </i>L. leaf litter, sugarcane bagasse and empty oil palm fruit bunch (<i>Elaeis guineensis</i> Jacq.) were converted into charcoal using carbonization process. An increase in temperature from 200°C to 400°C decreased charcoal yield gradually in all samples. Energy content in fresh biomass was lower than pyrolysed charcoal.Calorific value of fresh biomass and pyrolysed charcoal, respectively, was maximum in <i>C. equisetifolia</i> L. leaf litter (18.48 MJ/kg and 29.89 MJ/kg) and minimum in oil palm fruit bunch (16.96MJ/kg & 18.46MJ/kg). <br/> <br/>Page(s): 719-723 http://nopr.niscair.res.in/handle/123456789/5304 Title: Solid-state fermentation of waste cabbage by <i>Penicillium notatum NCIM NO-923</i> for production and characterization of cellulases <br/> <br/>Authors: Das, Arpan; Ghosh, Uma <br/> <br/>Abstract: Solid-state fermentation (SSF) of waste cabbage was carried out by <i>Penicillium notatum NCIM NO-923</i> for production of extracellular enzymes. Highest activities of carboxymethyl cellulase (CMC) (817.19 ±1.2 IU/gds) was obtained at 30°C and 48h fermentation time and that of filter paper activity (FPA) (67.49 ±1.33IU/gds) was obtained at 30°C and 24 h fermentation time. SSF of mixed substrate (cabbage and bagasse; 3:2 w/w) resulted in increase in CMC activity by 3277.3 ±1.22 and FPAby1280.76 ±1.33. Kinetic parameters were determined from Linewaver Burk plot. Both enzymes exhibited significant thermo stability up to 50°C. <br/> <br/>Page(s): 714-718 http://nopr.niscair.res.in/handle/123456789/5303 Title: Novel plant based formulations for short term preservation of animal skins <br/> <br/>Authors: Vijayalakshmi, K; Judith, R; Rajakumar, Suseela <br/> <br/>Abstract: This study presents monitoring at different temperatures and time of animal hides and skins subjected to bacterial degradation. Rate of collagen and non-collagenous protein degradation and microbial population dynamics were found to vary with temperature and storage period. Microorganisms (proteolytic, collagenolytic and keratinolytic) were found responsiblefor skin deterioration. <i>Acalypha indica</i> based formulation for curing animal skins was found viable, cost-effective and ecofriendly,reducing total dissolved solids (TDS) level to a considerable extent as compared to salt curing methods. <br/> <br/>Page(s): 699-707
