Scientists convert plant matter into chemicals
San Francisco, May 20: 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 said.

50 Munambam residents join BJP after Waqf (Amendment) Bill passed
Ernakulam: Hours after the Parliament passed the Waqf (Amendment) Bill, 50 residents from Munambam, a coastal village at the centre of the ongoing Waqf land dispute in Kerala, joined the Bharatiya Janata Party (BJP). All of them are Christians who had previously supported the Congress and CPI(M), according to Joseph Benny, convener of the Munambam protesters’ action committee.
The move came as BJP state president Rajeev Chandrasekhar visited Munambam and addressed the local protesters, assuring them of continued support. “This is an important day in the state's political history. This agitation has given strength to the Prime Minister and Parliament to pass the amendment Bill. We will be with you until you get back revenue rights over the land,” Chandrasekhar said. He added that the Bill has the potential to restore land rights to the people of Munambam and accused their elected MPs and MLAs of betrayal.
Around 600 families, mostly Christians, have been protesting for over 170 days after the Kerala State Waqf Board staked claim to the 400 acres of land they have inhabited for generations.
Meanwhile, the Catholic Church-linked Malayalam daily Deepika criticised the Congress and CPI(M) for rejecting the Church’s demand that their MPs support amending “anti-people sections” of the Waqf law. It accused them of attempting to instil fear among minorities by citing Sangh Parivar attacks on Christians in northern states and Manipur.
The BJP has positioned itself as the only party backing the cause of Munambam residents, while accusing both CPI(M) and Congress of prioritising Muslim interests in Kerala. Though both LDF and UDF later extended support to the Munambam agitation, their MPs voted against the amendments.
The Munambam area falls under the Ernakulam Lok Sabha constituency, represented by Congress MP Hibi Eden, and the Vypen Assembly segment, represented by CPI(M) MLA K N Unnikrishnan.
