the burning of household biofuels such as wood and manure. The third: agriculture, in the form of raising livestock, particularly methane-producing cattle.
Next-gen biofuels in 2012: Another mandate missed (and by a lot) Another year, another missed renewable fuel production mandate.
and once again next-generation biofuels will fall far short of the production volume mandated by Congress.
A National Resource Council report released in October said it's unlikely the U s. will meet specific biofuel mandates under the Renewable Fuel Standard by 2022
E coli bacteria that eats switchgrass to make fuel How do you solve a problem like next-gen biofuels?
Scientists find fungi that could give next-gen biofuels a boost
Next-gen toilets that could change the worldflush toilets get the job done. They also require a network of piped water, sewer and electrical connections,
New enzyme cuts cost of next-gen biofuelsthe advanced biofuels industry has failed so far to ramp up beyond pilot and demonstration projects.
Industrial enzyme maker  Novozymes said this week it has developed a super-efficient enzyme that could help biofuel producers reach that elusive commercially viable goal.
Traditionally, advanced biofuel producers have to use large amounts of expensive enzymes to get the desired end result.
and biofuel producers need only one-fifth of the enzyme dose compared to its competitors,
A Novozymes spokeswoman told me the enzyme could bring cellulosic ethanol costs down to $2 to $2. 50 a gallon for its biofuel customers.
The advanced biofuels industry has to find ways to cuts costs if it ever hopes to scale up commercially
USDA bets (again) on advanced biofuels Poet's cellulosic ethanol strategy: Dump fed loan, partner with DSM Bioengineering e coli to turn seaweed into fuel Next-gen biofuels in 2012:
Another mandate missed (and by a lot
NYC's urban agriculture potentialnew York City is the most dense major city in the U s. So how much land could possibly be available to farm?
 The joint venture, called POET-DSM Advanced Biofuels LLC, is scheduled to start production in the second half of 2013.
Bioengineering e coli to turn seaweed into fuel Fed-backed Range Fuels sells plant for pennies on the dollar Chemical giant BASF invests in biomass-to-sugar startup Next-gen biofuels in 2012:
including those meant to support biofuel production. The second looks more deeply into the case for sustainable and organic farming methods, using a long-term research study in Europe for specific evidence.
but on the increased use of biofuels. It maps this growth to existing production capacity
fertilizers, biofuels, irrigation equipment, management and infrastructure development. The second study is published in the June 2009 AMBIO:
where both food crops and biofuels are produced, as evidence. The study reaches back into 1995 for its data.
And better biofuels research, like re-engineering plants, so they do a better job of turning sunlight into fuels than current plants do.
growing salt-tolerant grasses for fodder or biofuel, and evaporating the concentrated saline the plant emits to produce salt, Science reports.
Salvaging biofuel from the West's pine beetle devastationmountain pine beetles have been ravaging western forests.
The company has found a way to produce biofuel from the dead wood that pine beetles have left in their wake.
it likely that the company can make biofuel from almost any cellulosic feedstock. Sticking to the dead stuff that can pose fire hazards to western communities seems well enough for now.
The team said there was no clear bias towards biofuel crops. Invisible hand But apart from direct investment, the new database suggests there are some worrying trends emerging."
But attempts to construct microorganisms that make biofuels efficiently certainly are though it will be impressive
and bacteria are the two most important biofuel technologies of the 21st century. As a replacement for oil, algae is extremely practical,
the cost of halophytic algae biofuel is less than the cost of petroleum trading at $70 per barrel or higher.
and Without Corna biofuel startup in Illinois can make ethanol from just about anything organic for less than $1 per gallon,
but biofuel experts said Coskata is the first to combine them. Doing so, they said,
In addition to land degradation, there also increasing competition for land and water between urban and industrial users and within the agricultural industry itself between livestock, staple crops, non-food crops and biofuel production.
Timothy Wise recently cited biofuel production as a oedemand shock that consumes crop production and yields price increases.
And Nestle Chairman Peter Brabeck-Letmathe also cited rising production of biofuel and the high subsidies it receives as the direct cause of rising food prices. oethe only difference is that with the food market you need 2,
synthetic fuels, biofuels, electricity, hydrogen, etc. â agriculture and food production: engineered crops, pest control, fertilizers, etc. â environmental protection and remediation:
and so far, the most important category for land use change has come from biofuels policies. A few things that synthetic biology might bring to us in agriculture are:
and an optimal source of biofuel. For our health, we may see new ways to target infectious diseases
