(1758) and its optimization for cellulase production <br/> <br/>Authors: Murugan, M; Srinivasan, M; Sivakumar, K; Sahu, Maloy Kumar; Kannan, L <br/> <br/>Abstract: Actinomycetes (35 strains), isolated from the gut of estuarine finfish Mugil cephalus collected from the Vellar estuary, were examined for cellulase activity. Strain CL-30, tentatively identified as Streptomyces actuosus, showed maximum cellulase activity at: pH 7, temperature 35°C, NaCl concentration 1-2%, carbon source sucrose and without addition of any amino acids. Molecular weight of cellulase determined by SDS-PAGE was 110 kDa. The study indicates the scope for the use of S. actuosus as an ideal organism for the industrial production of extracellular cellulase enzyme. <br/> <br/>Page(s): 388-393 http://nopr.niscair.res.in/handle/123456789/1260 Title: Biodegradation of synthetic textile dyes reactive red 195 and reactive green 11 by Aspergillus niger grp: An alternative approach <br/> <br/>Authors: Zope, Varsha; Kulkarni, Mohan; Chavan, Maya <br/> <br/>Abstract: Textile dyes (reactive red 195 and reactive green 11) were selected for biodegradation studies by Aspergillus niger grp using synthetic wastewater. Addition of glucose (1 g % w/v), ammonium sulphate (0.2 g % and 0.3 g % respectively for reactive red 195 and reactive green 11) favoured degradation. Optimum inoculum (size 1 g %, pH 7.0 and temp. 30 °C) was prepared for degradation of both the dyes. Static conditions favoured dye decolarization than shaking conditions. Under optimized conditions, degradation by Aspergillus niger grp was found to be: reactive red 195, 93.0; and reactive green 11, 80 %. Degradation of dyes was confirmed by UV- Spectrophotometric and TLC analysis. This indigenous isolate could be a potential organism for developing an efficient and effective technology for bioremediation of textile wastewater effluents carrying these dyes. <br/> <br/>Page(s): 411-414 http://nopr.niscair.res.in/handle/123456789/1259 Title: Development of steel primer from spent black liquor and short oil alkyd resin <br/> <br/>Authors: Mandavgane, S A; Rokde, S N; Gogte, B B; Subramanian, D <br/> <br/>Abstract: Primer paint has been developed based on lignin obtained from black liquor as a partial replacement (40%) for conventional alkyd resin. Efforts were made to prepare a novel alkyd resin with short oil length (20%) using chain stopper. Overall consumption of petroleum solvent (25%) in primer is lesser than conventional primer (40% solvent). The cost of present product is less than the conventional product. <br/> <br/>Page(s): 407-410 http://nopr.niscair.res.in/handle/123456789/1258 Title: Methane emission in landfill gas at two closed waste disposal sites in Istanbul, Turkey <br/> <br/>Authors: Ozcan, H Kurtulus; Nemlioglu, Semih; Demir, Goksel; Ozbas, Emine Elmaslar; Borat, Mehmet <br/> <br/>Abstract: In this study, methane emission was measured using micro gas chromatographic methods in Hasdal and Yakacik sanitary landfill areas in Istanbul city. Methane levels were found as 21.76-36.90% in Hasdal and 13.52-51.78% in Yakacik. Methane effects on environmental and public health were discussed. <br/> <br/>Page(s): 403-406
