  1. 1. Bioconversion of Lignocellulosic waste (wheat straw) for the production of biofuel<br />Desh Bandhu Gangwar<br />
  2. 2. INTRODUCTION<br /><ul><li>Lignocellulosic waste material provide world most abundant renewable resource produced through massive photosynthesis.
  3. 3. Cellulosic biomass is an alternative energy feed stock because supplies are abundant domestically and globally.
  4. 4. Ethanol production process only use energy from renewable energy source.</li></li></ul><li>The measured residue amount is approximately 39 millions metric tons of biodegradable cellulose.Pretreatment strategies:-mechanical combination -steam explosion -ammonia fiber explosion-acid and alkali pretreatment-biological treatment<br />
  5. 5. OBJECTIVE<br />To use suitable physical and chemical method for treatment of agro-waste.<br />Bioconversion of agro-waste into fermentable sugars.<br />The production of ethanol.<br />
  6. 6. METHODOLOGY<br />Lignocellulosic material<br />Pre - treatment<br />Hydrolysis<br />Fermentation<br />Ethanol<br />
  7. 7. SEPRATION OF HEMICELLULOSE, LIGNIN AND CELLULOSE COMPONENT OF WHEAT STRAW<br /> Wheat straw <br /> Steam Treatment <br /> Water soluble Insoluble <br /> (Hemicellulose) <br /> (Lignin + Cellulose) <br /> aq. Alkali Treatment<br /> soluble insoluble <br /> (Lignin)<br /> Adjust pH <br /> 7.0 <br /> Lignin Cellulose <br />
  8. 8. RESULTS<br />1. Percent composition of hemicellulose, lignin and cellulose in wheat straw<br />
  9. 9. 2.Effect of high pressure steaming <br />3.Estimation of total sugar concentration by by <br />(Scott and Melvin, 1953) method.<br />Extract 1 : Raw material treated with 1% acid (Concentrated H2SO4) <br />Extract 2: Raw material treated with 2% NaOH (alkali)<br />
  10. 10. 4. Estimation of total reducing sugar concentration by Miller et al., 1972) method.<br />.<br /> 5.Estimation of total celluloseconcentration by (Updegraph , 1969) method<br />
  11. 11. 6.Estimation of total cellulose concentration by (Updegraph, 1969) method<br />7.Estimation of total hemicelluloses concentration by (Bailey,1957) method.<br />
  12. 12. Effect of temperature on ethanol production <br />
  13. 13. Concentration of Ethanol<br />Effect of pH on ethanol production(acid treated wheat straw<br />Effect of pH on ethanol production(alkali treated wheat straw)<br />0.25<br />0.3<br />0.2<br />0.25<br />Concentration of Ethanol<br />0.15<br />0.2<br />pH 5<br />pH 5<br />0.15<br />pH 7<br />0.1<br />pH 7<br />0.1<br />0.05<br />0.05<br />0<br />0<br />1<br />2<br />3<br />4<br />1<br />2<br />3<br />4<br />Days<br />Days<br />Effect of pH on ethanol production <br />
  14. 14. CONCLUSION <br /><ul><li>It was concluded that extract 1 i.e. acid treated wheat straw contain maximum amount of total sugar, reducing sugar and xylose concentration in comparison to extract 2. Extract 1 i.e. acid treated extract gave slightly better production of fermentable sugar.
  15. 15. The best pH was pH- 5 and the best temperature was 300 C for the production of ethanol.</li></li></ul><li> Thank You<br />
