Some have suggested that we import more sugar-based ethanol from Brazil and we should indeed consider all sources of available ethanol â Â
whose enzymes can break cellulose down into simple sugars and immediately convert those into ethanol.
a modified Escherichia coli bacterium that can make biodiesel directly from sugars or hemicellulose, a component of plant fibre (see page 559).
LS9 says that the shift from sugars to biomass as a feedstock would reduce greenhouse gases even further.
The company has been working to convert sugars into tailored molecules for several years, says co-author Stephen del Cardayre, LS9's vice-president for research and development.
and municipal waste to sugars are getting cheaper. At a national US ethanol conference in Orlando, Florida, last week, biotech companies Novozymes and Genencor launched new generations of enzymes that they claim will cut the enzyme-related production costs of cellulosic ethanol

Instead of plants, the grasshoppers were fed with an artificial diet of high-sugar or protein-rich'biscuits'and he saw the same trend.
Scientists know how to convert these materials into simple sugars, but doing so requires energy and specialized enzymes, or both.
The ruling meant that GM beets which provide about half of the US sugar supply could not be grown until the US Department of agriculture (USDA) completes environmental-impact statements.
Business Biofuel offering Gevo, a company that genetically modifies microbes to produce chemicals from plant sugars,
although bamboo contains proteins, sugars and fats among other nutrients, most of its calories are locked in hard-to-digest cellulose fibres that make up plant cell walls.
Most herbivores have developed ways to break down cellulose into sugars; for example, cows and other ruminants have complicated digestive systems involving multiple stomachs filled with microbes that process plants many times to extract the maximum nutrition.
which resembled known genes for enzymes that break cellulose into simpler sugars. The microbial enzymes may help giant pandas to extract extra energy from the small amount of bamboo that they manage to process
Seaweed produces four kinds of sugars laminarin, mannitol, alginate and cellulose. The biggest fraction in brown seaweed is alginate,
which could then digest the alginate into simple sugars. The team also engineered the strain
so that it could convert those sugars into ethanol, enabling the direct production of ethanol from brown seaweed.
The main challenge in biofuels is not the ability to degrade complex carbohydrates and turn them into simple sugars,

Canadian company Iogen Energy in Ottawa announced on 30 april that it has shelved plans to build a large-scale facility in Manitoba to produce fuel ethanol from cellulose, the long molecular chain of sugars that forms
Most fuel ethanol is made by fermenting the sugars in grains or sugar cane, but cellulosic ethanol can be made from municipal waste, wood chips, grass,
But cracking apart the tough cellulose molecules is a lot harder than brewing up simple sugars.
they are decorated usually with plant-specific sugar molecules, which could prompt a dangerous immune reaction if injected into patients.
a structure where the problematic sugars are added. The engineered maize seeds produced proteins decorated with sugars that could be converted to human forms.
Richard Pattison a cell biologist at the Boyce Thompson Institute for Plant science in Ithaca, New york, calls the approach"very elegant.
Most attempts to solve the sugar problem require mutating the protein, which could disrupt its function,
However, making proteins with certain sugar patterns using these systems is still difficult or impossible.
4. They found that sugars and amino acids such as asparagine found in potatoes and cereals were making acrylamide (C3h5no) as a by-product of the Maillard reaction,
According to Beate Kettlitz, the group s director of food policy, 90%of large and medium-sized companies in Europe now select potato varieties with low levels of the sugars that can form acrylamide,
The same study in Zambia found that five more of the 150-odd complex sugars in breast milk seem to have a protective effect.
HIV-negative infants who consumed these sugars had a better chance of reaching their second birthday than did HIV-negative babies who drank breast milk lacking those sugars irrespective of their mothers'HIV status. Once a baby had caught HIV, however
Several labs are trying to identify how variation in the prevalence of the large sugar molecules in breast milk, collectively known as human milk oligosaccharides (HMOS), influences infant health.

and Brazil either using enzymes to break up plant material into fermentable sugars, or applying extremely high temperatures to break down biomass into syngas (hydrogen and carbon monoxide).
But unlike most ethanol factories, in which yeast feeds on sugars in foodstuffs such as maize (corn) kernels,
Producers must dismember large, indigestible molecules such as cellulose and hemicellulose to yield fermentable sugars. The process requires the biomass to be ground up and pretreated with acids.
A cocktail of enzymes must then be applied to chop up the tough biological polymers inside all before the yeast is added to the resulting sugars.

Once the bees have malnutrition ANYTHING could kill them easily. how bout we get one hive that only has gmo flowers
@Auroria The sugar comment has no place here. If this was a dietary article or one on diabetes or obesity it would fit but not here.
However the culprit was excess sugar and sodium intake combined with obesity; from a life time of eating processed foods!
Auroria I agree that sugar is a drug and that is extremely unhealthy (I avoid it).
You would die without sugar. Truth be told your body will start to make its own sugar
if you don't supply it (gluconeogenesis). Perhaps you should do a tad more research than just popular press--do some reading of primary sources.
I agree very much about sugar. People concentrate on illegal drugs when legal drugs kill many times more.
When sugar prices collapsed 10 of those mills closed but beets should still grow well in the California soil and climate.
Associated press in the San jose mercury news Ah another federally subsidized scam to increase the costs of sugar
There is chemically no difference between the sugars in honey and the high fructose corn syrup. Honey has some impurities in it (bacteria pollen other bee-related things)
solutions with a lot of sugar in it are denser than solutions that don't have a lot of sugar.
By calculating how much sugar was metabolized by the yeast one can roughly calculate the alcohol by volume.

#Field trial with lignin modified poplars shows potential for bio-based economythe results of a field trial with genetically modified poplar trees in Zwijnaarde Belgium shows that the wood of lignin modified poplar trees can be converted into sugars in a more efficient way.
These sugars can serve as the starting material for producing bio-based products like bioplastics and bio-ethanol.
The price of sugar has increased at a rate considerably above inflation over the last 30 years.
Sugar beet accounts for nearly 30%of the world's annual sugar production according to FAO and provides a source for bioethanol and animal feed.
But what perhaps may result amazing is that this sugar is probably sourced from a plant very similar to spinach or chard but much sweeter:
In fact this plant accounts for nearly 30%of the world's annual sugar production according to the Food and agriculture organization for the United nations (FAO.

The new study used data from several cycles of the California Health Interview Survey (CHIS) to examine dietary behaviors of very young children including their consumption of fast food sugar-sweetened beverages fruits
Although this and previous studies by the center have noted a general decline in the consumption of sugar-sweetened beverages among children in California that positive trend is reversed
For example an educational campaign to encourage parents to swap fruit juice for actual fruit would go far in reducing unnecessary sugar and increasing fiber and other nutrients the authors noted.
Unable to live on their own AMF are entirely dependent on their plant hosts for the sugars they need for food.
The proposed method consists in using powdered thymol mixed with powdered sugar. The mixture is spread in tin foil

Seventy years later T. reesei is a star in the world of biofuels because of its ability to churn out enzymes that chew through molecules like complex sugars.
The breakdown of large sugar polymers into smaller compounds that can then be converted further to fuel compounds is the final crucial step in the effort to make fuels from materials like switchgrass and corn stalks.
It's their job to break down complex sugars into simple sugars a key step in the fuel production process.
Nectar for example is basically sugar and water and so it is of value to British insects whether it is from a native garden plant or one from another part of the world.
Specifically she has managed to increase the amount of starch produced in the tobacco leaves by 700%and fermentable sugars by 500%.
We saw that the leaves of the genetically modified tobacco plants were releasing 500%more fermentable sugars.
With these sugars which could later be turned into bioethanol one could obtain up to 40 litres of bioethanol per tonne of fresh leaves--according to the theoretical calculation provided by the National Centre for Renewable Energies where the enzymatic test was conducted
The other half of the participants only received a small sugar cube at the beginning of the session
The sugar cube however dissolved quickly in their mouth so that the mouth muscles were free to simulate the pronunciation of the brand names.
Those participants who had received only a sugar cube and could thus internally train the brands'articulation demonstrated that there was a clear advertising effect.

The fungus Trichoderma reesei is already very good at breaking down tough plant material into sugars.
James Liao's lab at the University of California-Los angeles provided E coli bacteria that had been engineered to convert sugars into isobutanol.
and a recent doctoral graduate in Lin's lab. The fungi turned the roughage into sugars that fed both microbe species with enough left over to produce isobutanol.
Breaking cellulose down into sugar is hard work so T. reesei's tendency to do this and then share the spoils mark it as a cooperator.
Meanwhile the E coli use the sugars without offering the fungus anything in return which makes it a cheater.
because the fungi produce the sugars near their cell membranes which gives them the first crack at using the sugars.
The researchers can control E coli's advantage by tweaking how quickly the bacteria grow. Minty and others in Lin's group are now trying to improve on their energy conversion rate
Sugars derived from the grain of agricultural crops can be used to produce biofuel but these crops occupy fertile soils needed for food and feed production.
A plant cell wall mainly consists of lignin and sugar molecules such as cellulose. Cellulose can be converted to glucose
Lignin is a kind of cement that embeds the sugar molecules and thereby gives firmness to plants.
Unfortunately lignin severely reduces the accessibility of sugar molecules for biofuel production. The lignin cement has to be removed via an energy-consuming and environmentally unfriendly process.
Our results provide evidence that added sugar consumed at concentrations currently considered safe exerts dramatic adverse impacts on mammalian health the researchers say in a study set for online publication Tuesday Aug 13 in the journal
This demonstrates the adverse effects of added sugars at human-relevant levels says University of Utah biology professor Wayne Potts the study's senior author He says previous studies using other tests
fed mice large doses of sugar disproportionate to the amount people consume in sweetened beverages baked goods and candy.
and encouraged my family to do the same he adds noting that the new test showed that the 25 percent added-sugar diet--12.5 percent dextrose (the industrial name for glucose)
or added sugar Potts says. The mice tell us the level of health degradation is almost identical from added-sugar and from cousin-level inbreeding.
The study says the need for a sensitive toxicity test exists not only for components of our diet
A Mouse Diet Equal to What a Quarter of Americans Eatthe experimental diet in the study provided 25 percent of calories from added sugar--half fructose and half glucose--no matter how many calories the mice ate.
The diet fed to the mice with the 25 percent sugar-added diet is equivalent to the diet of a person who drinks three cans daily of sweetened soda pop plus a perfectly healthy no-sugar-added diet Potts says.
Ruff notes that sugar consumption in the American diet has increased 50 percent since the 1970s accompanied by a dramatic increase in metabolic diseases such as diabetes obesity fatty liver and cardiovascular disease.
For control mice corn starch was used as a carbohydrate in place of the added sugars. House Mice Behaving Naturallymice often live in homes with people
and then assigned either to the added-sugar diet or the control diet with half the males and half the females on each diet.
They all received the same added-sugar diet while in the mouse barns so the study only tested for differences caused by the mice eating different diets for the previous 26 weeks.
Added Sugar Impairs Mouse Lifespan and Reproduction--After 32 weeks in mouse barns 35 percent of the females fed extra sugar died twice the 17 percent death rate for female control mice.
There was no difference in the 55 percent death among males who did did and not get added sugar.
Ruff says males have much higher death rates than females in natural settings because they compete for territory
but there's no relation to sugar. --Males on the added-sugar diet acquired and held 26 percent fewer territories than males on the control diet:
control males occupied 47 percent of the territories while sugar-added mice controlled less than 36 percent.
Male mice shared the remaining 17 percent of territories. --Males on the added-sugar diet produced 25 percent fewer offspring than control males as determined by genetic analysis of the offspring.
The sugar-added females had higher reproduction rates than controls initially--likely because the sugar gave them extra energy to handle the burden of pregnancy
--but then had lower reproductive rates as the study progressed partly because they had linked higher death rates to sugar.
The researchers studied another group of mice for metabolic changes. The only differences were minor:
cholesterol was elevated in sugar-fed mice and the ability to clear glucose from the blood was impaired in female sugar-fed mice.
The study found no difference between mice on a regular diet and mice with the 25 percent sugar-added diet
when it came to obesity fasting insulin levels fasting glucose or fasting triglycerides. Our test shows an adverse outcome from the added-sugar diet that couldn't be detected by conventional tests Potts says.
Human-made toxic substances in the environment potentially affect all of us and more are discovered continually Potts says.
