Italy risks worst environmental disaster in decades
Italy risks its worst environmental disaster in more than two decades if the 2,400 tonnes of thick fuel in the capsized Costa Concordia pollutes one of the Mediterranean's most prized and pristine maritime reserves. Days after the 114,500 tonne liner capsized off the Tuscan coast, its vast wreck is shifting precariously on an undersea ledge, threatening to slide further and undermining plans to pump the oil out safely. With hopes of finding any survivors all but gone, experts warn that beyond the loss of lives, this could turn into Italy's worst maritime environmental emergency since the sinking of the Amoco Milford Haven, loaded with 144,000 tonnes of oil, off the coast of Genoa in 1991. Hopfuly the Italians find a way to get rid of all that fuel before it becomes a problem.
Biofuel breakthrough
Brown seaweed's potential as a vast source of biofuels has been highlighted with the announcement that scientists have found a way of converting all its major sugars into ethanol. A team reported in Science thursday (19 January) that it has engineered a microbe that will convert the sugars to ethanol, overturning one of the main obstacles to making the use of brown macroalgae, or seaweed, as a biofuel feedstock competitive. The prospective ethanol yield from brown seaweed is approximately two times higher than that from sugarcane and five times higher than maize, from the same area of cultivation. But its full potential cannot be reached because of the inability of industrial microbes to break down alginate, one of the three most abundant sugars in brown seaweed, commonly known as kelp, which is the most widely grown seaweed in the world. it will be a wonderful thing if the scientist find a way to use these plants for the better of the world.
