Center
for Lignocellulose Structure and Formation (CLSF) led by the Pennsylvania State University
The research team led by Rice graduate students Ruquan Ye and Yieu Chyan tried birch and oak, but found that pine's cross-linked
lignocellulose structure made it better for the production of high - quality graphene than woods with a lower lignin content.
It comprises a diverse mixture of bacteria, protists and fungi which can break down and extract essential nutrients from materials that are indigestible to most animals, such as
lignocellulose in wood.
The system operates under visible light, is stable beyond six days and is even able to reform
unprocessed lignocellulose,... Read more →
The EU - funded project known as DISCO (Discovery of Novel Enzymes & Reaction Mechanisms for
Lignocellulose Hydrolysis), is halfway through its four - year quest to develop more efficient and cost - effective enzyme tools from microorganisms to produce bioethanol from lignocellulosic biomass waste — such as spruce chips... Read more →
Seeking to find alternatives to ethanol as a fuel, the study established optimal pre-treatment conditions for turning
straw lignocelluloses and barley starch into fermentable sugars that -LSB-...]
Yet fungi are the dominant decomposers of plant -
derived lignocellulose, the major structural component of all plants, releasing nutrients from dead material to the soil, vital for agriculture.
Enzymes are the powerhouses behind biological chemistry, and the fungi discovered by O'Malley's group — like Anaeromyces robustus (named after the gray whale, partially based on how it looks under the microscope)-- have unusual and desirable characteristics, particularly the ability to
transform lignocellulose from plants into sugars.
The study is published as «
Biological lignocellulose solubilization: Comparative evaluation of biocatalysts and enhancement via cotreatment.»
«This can lead to combining solubilizing reagents with immobilized enzymes to chew up targets that are usually very resistant to degradation (e.g.,
lignocellulose waste site environmental contaminants) and convert them to energy or harmless byproducts.

Noting that the system's tolerance to a range of substrates is «particularly appealing» for H2 generation without need for
lignocellulose processing, the researchers are now focusing on replacing the Cd with a more environmentally benign metal.
«This newer technology significantly expands the slate of molecules we can make
from lignocellulose,» says Prof. Paul Dauenhauer of the University of Minnesota, who is co-director of CCEI and a co-author of the study.
The Department of Energy estimates the United States could produce as much as 1.3 billion tons per year
of lignocellulose, enough to replace 30 percent of the current U.S. petroleum consumption.
The system operates under visible light, is stable beyond six days and is even able to reform
unprocessed lignocellulose, such as wood and paper, under solar irradiation at room temperature, presenting an inexpensive route to drive aqueous proton reduction to H2 through waste biomass oxidation.
While lignins help give plants and trees structural rigidity, they must also be broken down or eliminated in order
for lignocelluloses to be used for production of papers, fuel and other bioproducts.
Together the two plants would produce, at best, 22 million gallons of ethanol a year by using sulfuric acid to break
the lignocellulose bonds and then burning the leftover lignin to power fermentation of the cellulose into ethanol.

Lignocellulose from wood waste or straw is the world's most common renewable raw material but, due to its complex structure, it is significantly more difficult to exploit than starch» explains Prof. Robert Mach from the Institute of Chemical Engineering at Vienna University of Technology.
Manufacturing biofuel from
lignocellulose is therefore a preferable option.
Due to diminishing petroleum reserves, non-food biomass (
lignocellulose) is an attractive alternative as a feedstock for the production of renewable chemicals and fuels.
However, efficient transformation of lignin, an integral and problematic component of
lignocellulose, into useful compounds is a major challenge, primarily because lignin is a randomized aromatic polymer that is resistant to decomposition.
Commercially prepared low - cal diets usually have (sugar) beet pulp or
lignocellulose (powdered wood) added to supply fiber.
The emerging aviation bio fuels will have starches, sugars, and biomass sources like oils and
lignocellulose and plants as main sources.
Researchers at Nanjing Tech University in China have developed a new pathway for the production of liquid hydrocarbon fuels from
lignocellulose.
