Antibacterial and Antifungal Activities of Mirabilis jalapa of Indian Origin
Abstract: The in vitro antimicrobial activity of Mirabilis jalapa leaf extract was studied against selected pathogenic and non-pathogenic microorganisms Escherichia coli, Bacillus subtilis, Klebsiella pneumoniae, Penicillium chrysogenum, Auriparus flaviceps and Trichoderma viridae by using agar diffusion and broth dilution methods. Leaves were extracted using solvents petroleum ether, chloroform and methanol. Among the solvents tested, petroleum ether and chloroform extracts showed good antimicrobial activity against the selected pathogens. The growth inhibitors were …

Biofertilizers: Yesterday, Today and Tomorrow
Abstract: India, being an agriculture-based country, there has always been a concern about crop improvement here. Chemical fertilizers increased crops yield, but eventually leached out soil, polluted water basins, degraded ecosystems, reducing soil fertility and thus causing damage to overall environment. Organic fertilizers are costlier and they released nutrients in the surrounding environment thus degrading soil and water quality and human health. Thus came into picture the use of GM crops …

Bioprocessing of Used X-ray Films for Silver Recovery by Thermoalkaliphilic Protease from Thermus aquaticus YT-1
Abstract: An environmentally benign enzymatic method for recovery of silver and polyethylene from used X-ray films was developed. This industrially scalable enzymatic process for the recovery of silver was investigated using the thermophilic alkaline protease from Thermus aquaticus YT-1. The rate of gelatin hydrolysis of X-ray film increased with the temperature till 70 ºC, suggesting enzyme stability till 70 ºC. Further, pH 10 was optimum for this process. Transparent polyethylene film …

Degradation of Synthetic Reactive Red Dye and Bioremediation of Textile Effluent Using Penicillium chrysogenum in a Fluidized-Bed Reactor
Abstract: 800x600 Normal 0 false false false EN-US X-NONE X-NONE Bioremediation of reactive red dye using five fungal species (Aspergillus niger, Penicillium chrysogenum, Fusarium oxysporum, Trichoderma harzianum and Sacchromyces cerevisiae) was studied in a shake flask system for 13 days. A. niger (91%) and P. chrysogenum (91%) were efficient decolorizers of red dye followed by F. oxysporum, and T. harzianum (84% and 53% respectively). Decolorization efficiency of P. chrysogenum in fluidized-bed …

Seroprevelance of Brucellosis in Goats and Sheeps in Different Regions of India, using B. melitensis Soluble Antigen in Plate-ELISA
Abstract: Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 In present study, we investigated 50 serum samples of goats from CIRG, Makhdoom and 470 serum samples of sheep from an organized animal shed of Northern India. These samples were tested for detection of anti-Brucella antidodies in goats and sheep using plate-ELISA. At total of 24% serum samples (24.4% females and 20% males) from CIRG, Makhdoom and 39.4% serum samples (41.2% …
