Most vegetable species use solar energy to create sugars from carbon dioxide and water. They store this energy in the form of glucose or starch molecules, oleaginous, cellulose, and lignocellulose .Biomass appears to be an attractive feedstock for three main reasons. First, it is a

What science is not able to achieve on a large commercial scale: develop simple cheap and reproducible method to digest and convert the cellulosic material into ethanol in one step prcess animals do it each day at least they digest the fibers and bring it down to sugar and fatty acid level . The microbes helping this process in the gut of cow and buffallow could provide the clue to getting some genes for doing the job at much lower price then billions of dollars being spent on finding the answers. However if its true or not only experimentation can tell.

Jatropha curcas grows wild in Udaipur division in Rajasthan. Chattisgarh state and several other northern states of India Under the micromission programme of Department of Biotechnology, Govt of India under chairmanship of Professor A.K. Sharma and Dr Renu Swarup, Director, and Dr Meenakshi Munshi Joint director work is being carried out in different states of the country regarding selection of eltie mateiral, its propagation, yield evaluation, genetic characterisation and developing proper agrotechnology. Under a Department of Biotechnology research project sanctioned to Professor Ashwani Kumar at University of Rajasthan, Jaipur 302004 work was inititiated on collection of eltie material.

An environmental factor that limits crop productivity or destroys biomass is referred to as a stress or disturbance (Grime, 1979). Salinity in soil or water is one of the major stresses and, especially in arid and semi-arid regions, can severely limit crop production (Shannon,1998). Over 800 million ha of land throughout the world is salt affected either by salinity 397 million ha or associated conditions of sodicity 434 million ha (FAO, 2005). Munns ( 2005) reviewed growth response due to salinty. The deleterious effects of salinity on plant growth are associated with (1) low osmotic potential of soil solution (water stress), (2) nutritional imbalance, (3) specific ion effect (salt stress), or (4) a combination of these factors (Ashraf,1994, Marschner1995).

The relative presence of microbiota may determine the use of partly digested food and regulate the food uptake and utilization in fatty and lean person ? Doctors know it better. Distal gut microbiota which constitutes the Firmicutes ( the largest bacterial phylum) containing more than 250 genera, including Lactobacillus, Mycoplasma, Bacillus and Clostridium and Bacteroidetes which include about 20 genera and Bacteroides thetaiotaomicron is one of the most abundant organisms.
