Es ocho veces m\u00e1s resistente que el acero inoxidable, transparente, ligero, conduce la electricidad y algunos aseguran que este material \u00abmaravilla\u00bb, como lo llaman algunos, transformar\u00e1 la agricultura tal y como hoy la conocemos.<\/strong><\/span><\/p>\n

Hablamos de la nanocelulosa cristalina, un material que se obtiene a partir de la compresi\u00f3n de fibras vegetales o se cultiva usando microorganismos como las bacterias<\/strong>.<\/span><\/p>\n

……..<\/span><\/p>\n

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

La nanocelulosa cristalina es considerada por algunos como una opci\u00f3n m\u00e1s ecol\u00f3gica y asequible que el publicitado grafeno, y sus aplicaciones incluyen la industria farmac\u00e9utica<\/strong>, cosm\u00e9tica, biocombustibles, pl\u00e1sticos y la electr\u00f3nica.<\/span><\/p>\n

Hasta hace poco una de las mayores preocupaciones de los adeptos a la nanocelulosa era c\u00f3mo producirla en grandes cantidades y a un bajo costo<\/strong>, pero cient\u00edficos creen que por fin han dado con la t\u00e9cnica para cultivar este material de forma abundante usando algas gen\u00e9ticamente modificadas.<\/span><\/p>\n

……….<\/span><\/p>\n

…..<\/span><\/p>\n

El investigador Malcom Brown, profesor de biolog\u00eda de la Universidad de Texas en Austin, Estados Unidos, y uno de los pioneros en el mundo en este campo de investigaci\u00f3n<\/strong>, explic\u00f3 recientemente durante el Primer Simposio internacional de Nanocelulosa, c\u00f3mo funcionar\u00eda el nuevo proceso.<\/span><\/p>\n

…..<\/span><\/p>\n

……..<\/span><\/p>\n

Se trata de un alga de la familia de las mismas bacterias que se usan para producir vinagre, conocidas tambi\u00e9n como cianobacterias<\/strong>. Unos organismos, que para su desarrollo s\u00f3lo necesitan luz solar y agua, y que tendr\u00edan la ventaja de absorber el exceso de di\u00f3xido de carbono en la atm\u00f3sfera, causante del efecto invernadero<\/span><\/p>\n

……<\/span><\/p>\n

……<\/span><\/p>\n

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

Pero ahora las investigaciones de Brown y su equipo, apuntan al uso de este alga azul-verdosa capaz de generar nanocelulosa naturalmente aunque en peque\u00f1as cantidades. Por ello, el equipo plantea modificarla artificialmente, introduciendo genes de la bacteria <\/strong>Acetobacter xylinum<\/em><\/strong> usada para producir vinagre<\/strong>.<\/span><\/p>\n

…..<\/span><\/p>\n

……..<\/span><\/p>\n

De este modo, el alga podr\u00eda producir el material en grandes cantidades y sin necesidad de aportar nutriente alguno, m\u00e1s all\u00e1 de suministrarle agua y exponerla a la luz del sol<\/strong>.<\/span><\/p>\n

It is eight times more resistant than stainless steel, transparent, light, conducts electricity, and some claim that this material \u00abwonder\u00bb, as they call it some, will transform agriculture as we know it today.<\/span><\/p>\n

….<\/span><\/p>\n

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

We speak of the crystalline nanocelulosa, material is obtained from plant fiber compression or cultured using microorganisms such as bacteria<\/span><\/p>\n

…………..<\/span><\/p>\n

nanocellulose crystal is considered by some as a more environmentally friendly and affordable than the advertised graphene, and its applications include pharmaceutical, cosmetics, biofuels, plastics and electronics.<\/span><\/p>\n

…………..
\nAccording to U.S. government estimates, by 2020 the industry will move production of some U.S. $ 600,000 million annually<\/span><\/p>\n

……………………<\/span><\/p>\n

Transform agriculture Until recently one of the major concerns of the followers of the nanocellulose was how to produce it in large quantities and at a low cost, but scientists believe that they have finally found the technique to cultivate this material liberally using genetically modified algae .<\/span><\/p>\n

…………….
\nThe researcher Malcolm Brown, professor of biology at the University of Texas at Austin, United States, and one of the pioneers in the world in this field of research, said recently at the First International Symposium nanocellulose, how the new process.<\/span><\/p>\n

………….<\/span><\/p>\n

It is an alga of the family of the same bacteria that are used to produce vinegar, known also as cyanobacteria. Some agencies, for its development only need sunlight and water, and which would have the advantage of absorbing the excess of carbon dioxide in the atmosphere, the greenhouse effect causing<\/span><\/p>\n

……………..<\/span><\/p>\n

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

But investigations of Brown and his team, now point to the use of this blue alga capable of generating co-fired naturally although in small quantities. Therefore the team proposes to modify it artificially, by introducing genes from the bacterium Acetobacter xylinum used to produce vinegar.<\/span><\/p>\n

………..<\/span><\/p>\n

In this way, algae could produce material in large quantities and without having to provide nutrient, further than to provide water and expose it to the light of the Sun.<\/span><\/p>\n
