Scientists have scoured cow rumens and termite guts for microbes that can efficiently break down
plant cell walls for the production of next - generation biofuels, but some of the best microbial candidates actually may reside in the human lower intestine, researchers report.

for plant tissues is extremely important due to the effect of freezing rate on the size of ice crystals,
cell hydration, and damage to
cell walls (Rahman, 1999).
«Together these studies tell a story about how mushroom - forming fungi evolved a complex mechanism
for breakdown of
plant cell walls in «white rot» and then cast it aside following the evolution of mycorrhizal associations, as well as the alternative decay mechanism of «brown rot,»» Hibbett said.

cell wall is incredibly complex and detailed, which is important
for plant biologists who want to change it to make biofuels,» she said.
Of the three
cell wall components, lignin is the most troublesome
for the biofuel industry because it limits the extraction of cellulose and hemicellulose
for biofuel production, according to Siobhan Brady, an assistant professor in the Department of
Plant Biology and Genome Center at UC Davis and a co-author of the study.

The group, led by principal investigator and Ames Laboratory scientist Emily Smith, is receiving $ 1 million a year
for three years from the DOE's Office of Science to develop a subdiffraction Raman imaging platform that will provide an unprecedented look at the specific chemical structures of
plant cell walls and then determine how best to deconstruct
plant material as a source of biofuels.
(She stopped eating frozen vegetables,
for instance, when she was taught that
plant cell walls expand and break down from low temperatures, sometimes resulting in lost nutrients.)
The ingredients list speaks
for itself: magnesium glycinate, ascorbyl palmitate (a fat - soluble form of Vitamin C), cellulose (what

wall, I attached it to a piece of stained scrap wood to create a shelf
for decorative accessories like a small
plant, air freshener, vase of flowers, extra t.p. or even just
