We have recently  finished  Master level postgraduate study on ethanol  production using immobilized   yeast cell using alginate to produce alcohol from fine apple wastes and  coconut waters  in laboratory scale .   Instead of operating the Bio system in a batch mode , fed batch operation can improve signifigatively the  productivity and very thankful for the members bring this  new process .
  Compared to convencional free cell process , the usability of the fixed yeast cell by support  is practicall process for ethanol production by big company  especially in Japan and USA due to high productivity.

This  new Bio process with high productivity can be  adopted to  farmer level for the Bio ethanol production  even in dryer area using  sweet sorghum as very well documented in the following excellent study from China

http://www.fao.org/docrep/T4470E/t4470e07.htm

 Compared to alginate the use ofvthe natural latex is more practical for small farmer use .More over  the long self life of the yeast  that can be  activated using air   can make the procees very great and simple to reducing the time

   Our  biofuel list  member can make this new inovative bio process combined with the extractive fermentation  using vegetable castor   and flash evaporation using solar energy to make the ethanol fuel for rural population bio fuel to be less energy intensive as this is negative side of the biofuel production process.

  The most of the rural  people in developing country spent 30 percent of the  their income for buying the cooking gas for the fuel.Making their own fuel can make them free from money lending pr and hence the bioethanol has a lot of role to play and all the member here too towards the sustainable globalization.

   Let  the members in our list who has  experience  join here , share and exchange the  same so that the one  in the remote area in all the world   too can  have the jouney to make the bioethanol anda BioD  to be simple and  practical for the great  green future There is no  need for the war and dependence  for  the limited non renewable petroleum  and big refinery as all  of us need food, fuel and peace  .
