Larsson's plan involves harnessing the metabolic powers of a sand-particle-fixing species of bacteria to produce sandstone

the value of harnessing the transformational powers of communities of microorganisms, called bioprocessing, is being realised in wastewater gardens.

These may be thought of as bacterial cities within our own, which are fed with and transform our waste organic matter into useful substances.

Bacteria that uses a tiny molecular machine to kill attacking viruses could change the way that scientists edit the DNA of plants,

and the engineering of energy-producing microbes, #says Luciano Marraffini of Rockefeller University. The biotech revolution that created drugs like EPO for anemia

The ability to make modular changes in the DNA of bacteria and primitive algae has resulted in drug and biofuel companies such as Amyris and LS9.

The bacteria used to culture milk are particularly prone to becoming infected with viruses that kill them, lowering productivity.

For decades, researchers had realized that bacteria had strange, repeating patterns of DNA sequence scattered throughout their DNA, known as clustered regularly interspaced short palindromic repeats (CRISPR).

The bacteria were keeping track of telltale bits of genetic code from viruses that might try to infect them,

Horvath recognized that this knowledge could be used to create bacteria that were more resistant to infection,

somehow the bacteria had the ability to target specific bits of genetic code. If scientists could harness that,

Horvath and Barrangou s paper set off a race to figure out what the bacteria s mysterious secret weapon was.

they found that the bacteria combined Cas9 with genetic material to create#oehoming molecules#that attack viruses.

Bacteria, like human beings and almost every other living thing, keeps its genetic code in a library of DNA molecules.

PHA is a biodegradable polyester that is produced naturally inside some bacteria under the conditions of excess carbon and limited nutrient availability.

Researchers are developing processes to make PHA at a commercial scale typically involving bacteria strains that have been modified genetically to boost production

The microorganisms feed on the plant-derived sugars and produce PHA. The PHA is separated then from the bacteria

and made into pellets that can be molded into plastic products. However that approach has several shortcomings:

Mango Materials'process uses bacteria grown in fermenters to transform methane and oxygen along with added nutrients (to supply excess carbon) into PHA.

Eventually the PHA-rich bacteria now literally swollen with PHA granules are removed from the fermenters

and the valuable polymer is separated via proprietary techniques from the bacteria. The PHA is rinsed then cleaned

In addition the process relies on a mixed community of wild bacteria that are obtained through natural selection rather than genetic engineering Using wild bacteria that are altered not genetically alleviates some people's concerns about genetically modified organisms.

And the use of a mixed community of wild bacteria reduces production costs because it eliminates the need to sterilize equipment.

The bacterium Agrobacterium tumefaciens which can cause tumours on plants shuttled foreign genes into plant genomes.

Developers then used genetic control elements derived from pathogenic plant viruses such as the cauliflower mosaic virus to switch on the genes.

And Agrobacterium is not essential either; foreign genes can be fired into plant cells on metal particles shot from a'gene gun'.

Now we can foresee this loophole getting wider and wider as companies turn more to plants and away from bacteria and other plant-pest organisms.

Nevertheless, Agrobacterium is still industry's tool of choice for shuttling in foreign genes, says Johan Botterman, head of product research at Bayer Bioscience in Ghent, Belgium.

But Agrobacterium isn't suitable for some new techniques. Many companies are developing'mini-chromosomes'that can function in a plant cell without needing to be integrated into the plant's genome.

However only a very small number of plants most notably legumes (such as peas beans and lentils) have the ability to fix nitrogen from the atmosphere with the help of nitrogen fixing bacteria.

Professor Edward Cocking Director of The University of Nottingham's Centre for Crop Nitrogen fixation has developed a unique method of putting nitrogen-fixing bacteria into the cells of plant roots.

when he found a specific strain of nitrogen-fixing bacteria in sugar-cane which he discovered could intracellularly colonise all major crop plants.

It is a naturally occurring nitrogen fixing bacteria which takes up and uses nitrogen from the air.

Plant seeds are coated with these bacteria in order to create a symbiotic mutually beneficial relationship and naturally produce nitrogen.

The biocatalysts used to release the hydrogen are a group of enzymes artificially isolated from different microorganisms that thrive at extreme temperatures some

The natural or engineered microorganisms that most scientists use in their experiments cannot produce hydrogen in high yield

because these microorganisms grow and reproduce instead of splitting water molecules to yield pure hydrogen. To liberate the hydrogen Virginia Tech scientists separated a number of enzymes from their native microorganisms to create a customized enzyme cocktail that does not occur in nature.

The enzymes when combined with xylose and a polyphosphate liberate the unprecedentedly high volume of hydrogen from xylose resulting in the production of about three times as much hydrogen as other hydrogen-producing microorganisms.

The energy stored in xylose splits water molecules yielding high-purity hydrogen that can be utilized directly by proton-exchange membrane fuel cells.

#Lack of energy an enemy to antibiotic-resistant microbesrice University researchers cured a strain of bacteria of its ability to resist an antibiotic in an experiment that has implications for a longstanding public health crisis. Rice environmental engineer Pedro Alvarez

and his team managed to remove the ability of the Pseudomonas aeruginosa microorganism to resist the antibiotic medication tetracycline by limiting its access to food and oxygen.

Over 120 generations the starving bacteria chose to conserve valuable energy rather than use it to pass on the plasmid--a small

A lot of the antibiotic-resistant bacteria originate in animal agriculture where there is overuse misuse and abuse of antibiotics.

We started with the hypothesis that microbes don't like to carry excess baggage he said. That means they will drop genes they're not using

The Rice researchers tested their theory on two strains of bacteria P. aeruginosa which is found in soil

and E coli which carries resistant genes directly from animals through their feces into the environment.

and/or oxygen through successive generations they found that in the absence of tetracycline both microbes dumped the resistance plasmid though not entirely in the case of E coli.

When a high level of tetracycline was present both microbes retained a level of resistance One long-recognized problem with antibiotics is that they tend to snatch defeat from the jaws of victory.

If any antibiotic-resistant bacteria are part of a biological mix whether in a person an animal or in the environment the weak microbes will die

and the resistant will survive and propagate; this process is known by biologists as selective pressure.

So there is incentive to eliminate the resistance plasmid from bacteria in the environment as close to the source as possible.

That may not kill the bacteria but it's enough to have bacteria notice a deficiency in their ability to obtain energy from the environment and feel the stress to dump resistant genes.

Alvarez has been chipping away at the problem since moving to Rice from the University of Iowa in 2004 even without American funding for research.

and the University of California Berkeley has discovered that a process that turns on photosynthesis in plants likely developed On earth in ancient microbes 2. 5 billion years ago long before oxygen became available.

This research concerns methane-forming archaea a group of microbes known as methanogens which live in areas where oxygen is absent.

This innovative work demonstrates the importance of a new global regulatory system in methanogens said William Whitman a professor of microbiology at the University of Georgia who is familiar with the study

Understanding this system will provide the tools to use these economically important microorganisms better. Methanogens play a key role in carbon cycling.

When plants die some of their biomass is trapped in areas that are devoid of oxygen such as the bottom of lakes.

Methanogens help convert the residual biological material to methane which other organisms convert to carbon dioxide--a product that can be used by plants.

Methanogens also play an important role in agriculture and human health They live in the digestive systems of cattle

Efforts to control methanogens in specific ways may improve feed utilization and enhance the production of meat

Methanogens are additionally a factor in human nutrition. The organisms live in the large intestine where they enhance the breakdown of food.

Some have proposed that restricting this activity of methanogens could help alleviate obesity. The team investigated an ancient type of methanogen Methanocaldococcus jannaschii

which lives in deep-sea hydrothermal vents or volcanoes where environmental conditions mimic those that existed on the early Earth.

Since methanogens developed before oxygen appeared on earth the evidence raises the possibility that thioredoxin-based metabolic regulation could have come into play for managing anaerobic life long before the advent of oxygen.
