BIOFUELS

BBC Earth (Asia) - - Science -

US biofuels com­pany Mas­coma has cre­ated a new yeast ca­pa­ble of con­vert­ing up to 97 per cent of crop waste into ethanol fuel. This ge­net­i­cally mod­i­fied strain is sig­nif­i­cantly more ef­fi­cient than pre­vi­ous bio­fuel-pro­duc­ing yeasts, which leave around a third of the tough plant ma­te­rial un­con­verted. The new yeast works in just 48 hours and its raw ma­te­ri­als – corn stalks, wheat straw and the ined­i­ble parts of sugar cane – are waste prod­ucts of com­mer­cial farm­ing, so are abun­dant and cheap.
