Biodiesel is an attractive alternative fuel to diesel engines because it is renewable and non-polluted fuel that can be produced from plant and animal fats. The plant and animal fats derived oil can be used as biodiesel either solely or its blending with diesel. Further, it can be used in either extracted form or after transesterification. Madhuca indica fruit oil was evaluated in this study to find out its suitability to be used as biodiesel. The oil was extracted from Madhuca indica fruits using diethyl ether and ethanol (3:1) by centrifugation method. Extracted oil was divided into three equal parts. One part of oil was blended with 5% diesel, second part was transesterified to produce methyl esters and the third part was kept as such. All the three parts of oil were evaluated and compared for their suitability to use as biodiesel on the basis of various physico-chemical parameters. Content of specific gravity, iodine value, free fatty acids, and kinematic viscosity were found lower than the upper limits prescribed by ASTM (American Standards for Testing of Materials) and EN (European Standards) in decreasing order of pure oil>transesterified oil>blended oil, pure oil>blended oil>transesterified oil, pure oil>blended oil>transesterified oil, and pure oil>blended oil>transesterified oil, respectively. Content of sulfur and acid value were higher in all the three types of oil than the upper limit prescribed by ASTM and EN. Cetane number and flash point of transesterified oil were within the limits of ASTM and EN whereas their values were below the standard limits in blended oil and higher in pure oil for flash point. No standards has been given by ASTM and EN for saponification number, ethanol content and cloud point and they follow the decreasing trend of pure oil>blended oil>transesterified oil for saponification number and cloud point and blended oil>transesterified oil>pure oil for ethanol content. © 2015 The Council of Scientific and Industrial Research, New Delhi.

The present research emphasizes on degradation of azo dyes from simulated textile wastewater using down flow microaerophilic fixed film reactor. Degradation of simulated textile wastewater (COD 7200mg/L and dye concentration 300mg/L) was studied in a microaerophilic fixed film reactor using pumice stone as a support material under varying hydraulic retention time (HRT) and organic loading rate (OLR). The intense metabolic activity of the inoculated bacterial consortium in the reactor led to 97.5% COD reduction and 99.5% decolorization of simulated wastewater operated under OLR of 7.2kgCODm3/d and 24h of HRT. FTIR, 1H NMR and GC-MS studies revealed the formation of lower molecular weight aliphatic compounds under 24h of HRT, leading to complete mineralization of simulated wastewater. The detection of oxido-reductive enzyme activities suggested the enzymatic reduction of azo bonds prior to mineralization. Toxicity studies indicated that microbial treatment favors detoxification of simulated wastewater. © 2014 Elsevier Ltd.

The study exemplifies sequential anaerobic-microaerophilic bioremediation process for treatment of textile industrial wastewater having 10,000 mg l-1 of COD and 3330 mg l-1 of the BOD. The experimental results showed that, in an anaerobic phase, with cattle dung slurry as an initial feed, nearly 60% of COD and BOD was removed from textile wastewater at an optimum HRT of 2d and OLR of 5.0 kg COD m-3d-1. Further, COD and BOD removal efficiency of bacterial consortium BDN was enhanced upto 97% under microaerophilic phase, at HRT of 12 h. Moreover, optimum color removal (80%) was observed in anaerobic reactor. The combine treatment process removed 99% of color at combine HRT of 60 h. The activity of lignin peroxidase was higher as compared to other enzymes studied. The UV-vis, FTIR, 1H NMR and GC-MS analyses of treated textile industrial wastewater revealed the degradation of dye compounds and formation of lower molecular weight intermediates. The toxicity of textile industrial wastewater decreased subsequently from anaerobic to microaerophilic treatment process. © 2015 Elsevier Ltd.

Overall measurement of methanogenic activity of sludge and or slurry is thought as a key for understanding the basic physiology of anaerobic consortia involved in anaerobic digestion process of an alternative biomass. In this study, the methanogenic activity of biogas plant slurry was used to evaluate the anaerobic digestion of ossein factory wastes such as sinews and primary clarified bone waste (PCBW) and cyanobacterial biomass in standard assay conditions. A maximum methanogenic activity was reported here when ossein factory wastes mixed with cyanobacterial biomass in specific proportions in which sinews and PCBW alone also favored to a significant methane yield. Cyanobacterial biomass alone did not give a desirable methanogenic activity. Approximately 48% of total solids were destroyed from these wastes after 30 days. This study gives information on the use of these wastes with suitable proportions for taking an effort in a large-scale anaerobic digestion in an effective way of ossein factory. © 2009 Humana Press.

The objective of the present work was to evaluate the ossein factory wastes, which include primary clarified bone waste (PCBW) and sinews for methane production, by monitoring methanogenic activity of predigested biogas plant slurry. A specific methanogenic activity of biogas plant slurry (anaerobic seed) was measured at 38 degrees C using different proportions of ossein factory wastes in an assay medium. The pH of slurry was intensively maintained until course of digestion. A moderate proportion of both substrates showed a maximum methane production at 20 days of incubation in batch mode. However, a maximum cumulative methane yield achieved by biogas plant slurry on PCBW was low as compared to sinews. The best organic matter degradation was achieved even at a high proportion of ossein factory wastes used in digesters. These substitutes would be useful, without seriously reducing total gas production, for methane production if they partially mixed with cattle dung. As a result of this preliminary study, we suggest that ossein factory wastes are potential alternative sources for biogas production in ossein factory.

Solanum melongena is a vegetable plant but its stem has no economic use and generally burnt in fields. Present study is an attempt to convert it into vermicompost through the activities of Eisenia foetida. The study was focused on changes occurred in activities of various enzymes and in microbial count during the vermicomposting process. Vermicompost was prepared in pits of (45×45times;21) cm (ltimes;btimes;h) size prepared on cemented floor. Four treatments were laid out in triplicates viz. Control: Buffalo dung + Eisenia foetida, T1: Buffalo dung +Solanum melongena stem, T2: Buffalo dung + Solanum melongena stem + Eisenia foetida and T3: Solanum melongena stem + Eisenia foetida. Vermicomposting materials were analyzed at monthly interval for the activities of CMCase, β-glucosidase, FPase, amylase, xylanase, acid and alkaline phosphatase and the count of bacteria, azatobacter, phosphate solubilizer, yeast, fungi and actinomycetes. Results show that the activities of all the enzymes and counts of all the microbial species increased progressively with time but urease activity shows the reverse trend and decreased with time. Statistically the effect of treatments for all these parameters was significant at 5% level of significance except for the counts of yeast and actinomycetes.

Virtualization is very important factor to reduce cost of data warehouse deployment. It can reduce cost as well as tremendous pressure of managing devices, storage servers, application models and man power. In current era, data warehouse is very effective concept that can make huge impact in organizational decision support system. Unlike database systems, data warehouse systems take large amount of time and cost to deploy and develop in-house system for an organization. This is the reason that people now think about cloud computing as a solution of the problem instead of implementing their own data warehouse system. This paper is about, how cloud computing environment can be established as an alternative of data warehouse system. It will also throw some light about better environment choice for the organizational need. Organizational data warehouse and EC2 (Elastic Cloud Computing) are discussed with different parameters like ROI, security, scalability, robustness of data, maintenance of system etc. Paper will help in comparative analysis of both the systems. © 2014 IEEE.
