Thedatabase allows managing of information related to carbon dioxide fixation utilizing microbes belongingto four different classes i.e. microorganisms, genus listing, mechanisms and literature. The database canhelp in devising biological strategies for reducing carbon dioxide from the environment. It can also serveas comprehensive knowledgebase to search the microbes capable of utilizing carbon dioxide.   2009 Elsevier Ltd. All rights reserved. 1.

Overview  Global warming – the most noticeable environmental problemis an unusual rise in earth’s temperature mainly due to the accu-mulation of greenhouse gases. Today global warming hassubstantial but undefined impacts on our ecosystem which areexpected to become more pronounced in the coming years ( Jarviset al., 2009). To overcome the effects of global warming there is anurgent need to think of various innovative ways for fixing CO 2 through physical, chemical and biological processes. Among thethree, the biological fixation using microorganisms has beenaccepted as a potential measure to mitigate global warming. It isbelievedtobeanenvironmentfriendlyandenergyefficientprocessas the biomass formed by fixation of CO 2  can be used for theproduction of bioenergy, microbial biodiesel, biohydrogen. Thesecan serve as an alternative to conventional energy sources such asfossil fuel and hence reduce the pressure to some extent (Bruce,2008). Till now, in many biological fixation processes, the photo-synthetic activity of microalgae have been exploited for mitigatingglobal warming (Wang et al., 2008). But besides microalgae there are some microbes i.e. bacteria and archaea that can too contributein reducing global warming ( Jessup et al., 1998). So far scientists have identified 5 different pathways through which microbes canfix CO 2  into biomass (Rudolf, 2007; Tributsch, 2003). This infor- mation can contribute to devise the technologies that emphasizeon the role of microbes in curbing the emission of greenhouse gasi.e. CO 2  from the industrial process. *  Correspondence to: Rita Kumar, Environmental Biotech Division, 5th Floor,Room No: 506, 507, Institute of Genomics and Integrative Biology, New Delhi, India.Tel.:  þ 91 011 2766156x154; fax:  þ 91 011 27667471.

Visualization The main aim of CSD, version 1.0, is to integrate all the dataavailable to date for the fixation of CO 2  using microbial strains. TheCSD web interface enables us to categorize all the informationwithin various classes on a single page (Fig. 1). Firstly, ‘‘Microor-ganisms’’, which assembles all the microbial species involved inculling CO 2  from their surrounding environment. Second, ‘‘Genuslist’’ contains data describing the genus of all species reportedunder Ist class. Each genus is linked to NCBI (National center forbiotechnology information) page that not only enables users tofurtherexplorethe knowledgeon relatedspecies, but also providesthe taxonomic characteristics of the genus. The third class ‘‘Mech-anism’’ informs about the mode of incorporation of CO 2  in themetabolic pathways of these organisms. More detailed informationabout these pathways has beenprovided as a hyperlink to MetaCycdatabase.Lastly the ‘‘Literature’’ class presents the list of research papersfrom which the data has been extracted. The database is expectedto expand further in order to keep up with the pace of scientificresearch in this area. Besides these classes there are other twoimportant features in the database that will help users in manyways. Foremost the search tool option that will facilitate rapidsearchtothedatafora particularmicrobial species.Secondly, otherrelevant databases as mentioned in the CSD will help theresearchers to collect more information. 4. Conclusions In the present work (CSD), we describe a comprehensive data-base for managing scattered information regarding microbialCO 2  utilization. This platform of comprehensive knowledge willdefinitely motivate researchers to device new biological approachto curb global warming. Information is managed in a simple anduser friendly way and it can be retrieved by simple search tool.
