A team led by an Indian-origin scientist from Sandia National Laboratories in California has demonstrated a new technology based on bio-engineered bacteria that can make it economically feasible to produce chemicals from renewable plant sources.

The technology converts tough plant matter, called lignin, for wider use of the energy source and making it cost competitive.

“For years, we have been researching cost-effective ways to break down lignin and convert it into valuable platform chemicals,” Sandia bioengineer Seema Singh said.

“We applied our understanding of natural lignin degraders to E. coli because that bacterium grows fast and can survive harsh industrial processes,” she added in the work published in the “Proceedings of the National Academy of Sciences of the United States of America”.

Lignin is the component of plant cell walls that gives them their incredible strength. It is brimming with energy but getting to that energy is so costly and complex that the resulting biofuel can’t compete economically with other forms of transportation energy.

Once broken down, lignin has other gifts to give in the form of valuable platform chemicals that can be converted into nylon, plastics, pharmaceuticals and other valuable products.

Singh and her team have solved three problems with turning lignin into platform chemicals: cost, toxicity and speed.

Engineering solutions like these, which overcome toxicity and efficiency issues have the potential to make biofuel production economically viable.

“Now we can work on producing greater quantities of platform chemicals, engineering pathways to new end products, and considering microbial hosts other than E. coli,” Singh (IANS)

California’s Net Neutrality Law Causes A Law Suit From The US Government

Oregon, Washington and Vermont have approved legislation related to net neutrality, but California's measure is seen as the most comprehensive attempt.

California Gov. Jerry Brown has approved the nation’s strongest net neutrality law, prompting an immediate lawsuit by the Trump administration and opening the next phase in the battle over regulating the internet.

Advocates of net neutrality hope California’s law, which Brown signed Sunday to stop internet providers from favoring certain content or websites, will push Congress to enact national rules or encourage other states to create their own.

However, the U.S. Department of Justice quickly moved to halt the law from taking effect, arguing that it creates burdensome, anti-consumer requirements that go against the federal government’s approach to deregulating the internet.

“Once again the California Legislature has enacted an extreme and illegal state law attempting to frustrate federal policy,” U.S. Attorney General Jeff Sessions said in a statement.

The Federal Communications Commission repealed Obama-era rules last year that prevented internet companies from exercising more control over what people watch and see on the internet.

The neutrality law is the latest example of California, ground zero of the global technology industry, attempting to drive public policy outside its borders and rebuff President Donald Trump’s agenda.

Brown did not explain his reasons for signing the bill or comment on the federal lawsuit Sunday night.

Supporters of the new law cheered it as a win for internet freedom. It is set to take effect January 1.

“This is a historic day for California. A free and open internet is a cornerstone of 21st century life: our democracy, our economy, our health care and public safety systems, and day-to-day activities,” said Democratic Sen. Scott Wiener, the law’s author.

It prohibits internet providers from blocking or slowing data based on content or from favoring websites or video streams from companies that pay extra.

Telecommunications companies lobbied hard to kill it or water it down, saying it would lead to higher internet and cellphone bills and discourage investments in faster internet. They say it’s unrealistic to expect them to comply with internet regulations that differ from state to state.

USTelecom, a telecommunications trade group, said California writing its own rules will create problems.

“Rather than 50 states stepping in with their own conflicting open internet solutions, we need Congress to step up with a national framework for the whole internet ecosystem and resolve this issue once and for all,” the group said in a Sunday statement.

Net neutrality advocates worry that without rules, internet providers could create fast lanes and slow lanes that favor their own sites and apps or make it harder for consumers to see content from competitors.

That could limit consumer choice or shut out upstart companies that can’t afford to buy access to the fast lane, critics say.

The new law also bans “zero rating,” in which internet providers don’t count certain content against a monthly data cap — generally video streams produced by the company’s own subsidiaries and partners.
