发帖数: 1619 | 4 BEIJING -- A doubling of pork prices last month sent Chinese consumer
inflation to its highest level in nearly eight years, constraining Beijing's
ability to stimulate the economy as growth continues to slow.
China's consumer-price index rose 3.8% in October from a year earlier, the
National Bureau of Statistics said Saturday -- higher than a median forecast
of 3.5% by economists polled by The Wall Street Journal, and far outpacing
September's 3.0% reading.
As it has all year, October's jump in ... 阅读全帖 |

发帖数: 22 | 7 General Merchandise is widely considered to be nonfood items. For example, a grocery store is generally broken up into the grocery section and the general merchandise section. This may include cleaners, personal hygiene products, paper goods, seasonal items such as cards and decor, and auto/electrical items. |

The global demand for food could double in another 40 y owing to growth in
the population and food consumption per capita. To meet the world’s future
food and sustainability needs for biofuels and renewable materials, the
production of starch-rich cereals and cellulose-rich bioenergy plants must

发帖数: 773 | 13 Science -- Could Wood Feed the World
http://news.sciencemag.org/sciencenow/2013/04/could-wood-feed-t
The main ingredient of wood, cellulose, is one of the most abundant organic
compounds on Earth and a dream source of renewable fuel. Now, bioengineers
suggest that it could feed the hungry as well. In a new study, researchers
have found a way to turn cellulose into starch, the most common carbohydrate
in the human diet.
Ethanol is today's most common biofuel used to power vehicles. It's
typically... 阅读全帖 |

发帖数: 430 | 17 Congratulations! I guess this is a really big finding. People won't eat it.
But these starch/amylose can be used as feedstocks to grow yeast or bacteria
to produce beer, amino acids and other bulk chemicals. |

发帖数: 773 | 23 Cutting it from discussion.
This cellulose-to-amylose biotransformation could be scaled up by increasing
the stability of CBP and PGP and decreasing their production costs in terms
of $/kg enzyme (Fig. S6) because this combined cellulose-hydrolyzing and
starch-synthesizing enzyme cocktail did not involve any labile coenzymes [e.
g., CoA and NAD(P)] (Fig. 1A); no glucose released from the cellulose was
wasted (Fig. 1); only two more enzymes were added and they can be re-used
easily by a magnetic ... 阅读全帖 |
