Cient\u00edficos surcoreanos han logrado desarrollar una nueva t\u00e9cnica capaz de producir por primera vez gasolina a partir de bacterias intestinales E. coli<\/strong> gen\u00e9ticamente modificadas.<\/span><\/span><\/p>\n

En un art\u00edculo difundido por la revista cient\u00edfica\u00a0‘Nature’<\/a> y titulado ‘Producci\u00f3n microbiana<\/strong> de los alcanos de cadena corta’, un equipo de investigaci\u00f3n dirigido por el profesor Sang Yup Lee, del Departamento de Ingenier\u00eda Qu\u00edmica y Biomolecular del Instituto Superior Coreano de Ciencia y Tecnolog\u00eda (KAIST, por sus siglas en ingl\u00e9s), revela haber logrado producir gasolina a partir de bacterias intestinales.

\nEn el documento, los cient\u00edficos explican c\u00f3mo manipularon el metabolismo de \u00e1cidos grasos<\/strong> de las bacterias Escherichia coli (E. coli), para proporcionar derivados de esos \u00e1cidos m\u00e1s cortos que los \u00e1cidos grasos intracelulares normales, introduciendo una nueva ruta sint\u00e9tica para la bios\u00edntesis de alcanos (hidrocarburos) de cadena corta.

\n\u00abLa importancia de este descubrimiento radica en que no hay que pasar por otro proceso para depurar el aceite creado por la E. coli para producir gasolina. <\/strong>Hemos logrado convertir la glucosa o los residuos de la\u00a0biomasa<\/a> directamente en gasolina\u00bb, dijo Lee, quien explic\u00f3 que el fluido generado de esta forma tiene una composici\u00f3n y propiedades qu\u00edmicas id\u00e9nticas a la gasolina convencional.

<\/span><\/p>\n

\nNo obstante, los d\u00edas en que los coches estar\u00e1n propulsados por derivados de las bacterias parecen estar todav\u00eda lejos. De momento, el KAIST ha logrado obtener 580 miligramos de gasolina por cada litro de aceite bacteriano producido. \u00abNuestro pr\u00f3ximo objetivo es producir tres gramos de gasolina por litro y luego elevarlo a 10 o incluso 20 gramos y entonces ser\u00e1 competitivo\u00bb, se\u00f1al\u00f3 el investigador surcoreano.

\nEsta no es la primera vez que se obtiene\u00a0combustible<\/a> de origen microbiano (recientemente un equipo de cient\u00edficos brit\u00e1nicos logr\u00f3 obtener tambi\u00e9n di\u00e9sel), pero s\u00ed es la primera vez que se puede demostrar la fabricaci\u00f3n de gasolina, el combustible m\u00e1s demandado en el mundo

Scientific <\/span>South Koreans<\/span> have developed a new technique capable of producing for the first time gasoline from intestinal bacteria e. coli genetically modified<\/span><\/span><\/p>\n

<\/span><\/p>\n

<\/span><\/p>\n

In an article released by the science journal ‘Nature’, entitled ‘Microbial production of short-chain alkanes’, a research team led by Professor Sang Yup Lee, Department of chemical engineering and Biomolecular’s top Korea Institute of science and technology (KAIST, by its acronym in English), reveals have managed to produce gasoline from intestinal bacteria.<\/span> <\/span><\/span><\/p>\n

<\/span><\/p>\n

………………..<\/span><\/span><\/p>\n

<\/span><\/p>\n

In the document, the scientists explain how manipulated the metabolism of fatty acids in bacteria Escherichia coli (e. coli), to provide those shorter than normal intracellular fatty acids acids derivatives, by introducing a new synthetic route for the biosynthesis of short-chain alkanes (hydrocarbons).<\/span><\/span><\/p>\n

<\/span><\/p>\n

…………..<\/span><\/span><\/p>\n

<\/span><\/p>\n

<\/span><\/span><\/p>\n

<\/span><\/p>\n

\u00abThe importance of this discovery is that there is no to go through another process to debug the oil created by e. coli to produce gasoline.\u00bb We have achieved directly convert glucose or biomass waste into gasoline\u00bb, said Lee, who explained that the fluid generated in this way has a composition and chemical properties identical to conventional gasoline.<\/span><\/span><\/p>\n

<\/span><\/p>\n

<\/span><\/p>\n

<\/span><\/span><\/p>\n

<\/span><\/p>\n

However, the days when cars will be powered by derivatives of the bacteria seem to be still far away. At the moment, the KAIST has managed to get 580 milligrams of petrol per liter produced bacterial oil. \u00abOur next goal is to produce three grams of fuel per litre and then raise it to 10 or even 20 grams and will then be competitive\u00bb, the South Korean investigator said.<\/span><\/span><\/p>\n

<\/span><\/span><\/p>\n

<\/span><\/p>\n

This is not the first time that gets fuel from microbial origin (recently a team of British scientists managed to also get diesel), but it is the first time that the manufacture of gasoline, the most sought-after fuel in the world can be shown<\/span><\/span><\/p>\n
