A fluorescent mushroom distributed in Brazil will emit green fluorescence in the dark, and Russian and Brazilian researchers are expected to use other biochemical experiments by analyzing the luminescence mechanism of this mushroom and synthesizing fluorescein molecules.

In some parts of Brazil under the palm trees there is a local people commonly known as “coconut flower” fluorescent mushrooms. In the sun this mushroom is yellow and white color, but in the night or dark cave it can emit green fluorescence, attracting insects to help spread the spore propagation. How is this mushroom glowing? The Institute of Bioorganic Chemistry of the Russian Academy of Sciences and the Brazilian colleagues have studied this.

Researchers reported in the new issue of “Progress in Science” that they analyzed the cells of the mushroom, extracted the proteins and fluorescein molecules associated with the emission of fluorescence, and analyzed these substances by gas chromatography and mass spectrometry. Under the chemical changes that occur. It was eventually found that some of the protein molecules in the mushroom cells used the intracellular oxygen and adenosine triphosphate to oxidize their own specific fluorescein to emit green light.

The researchers also found that the above-mentioned fluorescein molecules consist of two important fragments. They mimicked the structure of these two fragments and synthesized six kinds of fluorescein molecular fragments with chemical fluorescent substrate-alfa pyrone and used them to replace the natural fluorescein molecular fragments of mushrooms one by one. It was found that there were five artificial fragments Natural fragments collaborate to produce orange, yellow, light green, blue, and light blue in the absence of mushrooms, individually cultured.

Researchers say the study has made them not only aware of the mechanism by which fluorescent mushrooms emit light in the dark, but also have a way to control their fluorescent color. It is expected that the cells will emit light in animal and plant cell experiments in order to observe their biochemistry Variety. In addition, the team is also prepared to modify the fluorescent mushroom gene, so that the synthesis of all the luciferin molecular fragments, in order to cultivate the colorful “rainbow” mushrooms.

From the theoretical level, China’s coalbed methane industry has become more mature, but the actual development and utilization is in the initial stage, the industrialization process is slow, still subject to mineral rights overlap, the lack of standards and other constraints. In view of the development and utilization of coalbed methane is of great significance, “13th Five-Year” period to speed up the development and utilization of coalbed methane is imminent.

Coalbed methane is a kind of unconventional natural gas associated with coal, also known as gas gas, the main component is methane (methane content> 85%). Reasonable development and utilization of coalbed methane, to improve China’s energy structure, reduce greenhouse effect, reduce the dependence on oil imports and so on is of great significance.

Coalbed methane

The development and utilization of coalbed methane not only help to solve the environmental pollution, but also to achieve the use of resources, with energy efficiency, safety benefits, environmental benefits and so on.

In particular, in the energy efficiency, coalbed methane clean, convenient, cheap, high calorific value; in terms of safety benefits, to prevent gas accidents; in environmental benefits, coal-bed methane does not produce harmful gases, reducing environmental hazards.

China is the world’s third largest coalbed methane resource, second only to Canada and Russia. It is estimated that China’s coalbed methane resources in about 30 ~ 36.8 trillion m3 or so, mainly in the Ordos, Jinzhongnan region, Turpan-Hami basin, Junggar Basin and so on.

Although the coalbed methane is rich in resources, but the actual development and utilization is lagging behind, according to the prospective industry research institute released the “China CBM industry economic evaluation and investment strategic planning analysis report” statistics, in 2014, China’s total annual output of coalbed methane is about 118 Billion m3, of which the ground pumping capacity of only 2.3 billion m3.

China’s coalbed methane not only the development of limited strength, and direct commercial utilization is low. This is mainly because the use of coalbed methane is the nearest consumption model, and focused on civilian, gas power generation, industrial raw materials and other fields.

On the other hand, the development and utilization of coalbed methane technical barriers, but also lead to industrial development is often blocked one of the important reasons. In the technology can not be completely resolved before the problem, the development and utilization of coalbed methane is still difficult to make great progress.

However, at home and abroad are increasing the development and utilization of coalbed methane technology research, such as has been announced the efficient production technology, coalbed methane catalytic cracking technology. With the technological progress, the development and utilization of coalbed methane is expected to be on the steps.

In general, coalbed methane has a bright future, but the development of more factors, slow progress in industrialization. To this end, China in the 13th Five-Year Plan, will accelerate the development of coalbed methane on a prominent position, and made the 2020 coalbed methane production of 40 billion cubic meters of the target.

The future with the specific implementation of the relevant policies, coalbed gas pipeline network to achieve a wide range of coverage, as well as technological innovation to bring the cost of decline, coalbed methane is expected to move towards rapid development.

May 11 at 24 o’clock, China will usher in the ninth time during the refined oil price adjustment window, the industry forecast the current round of domestic refined oil prices are expected to usher in a more substantial reduction.

Oil production accounted for more than one-third of the world’s OPEC in November 30, 2016 reached a cut agreement. In December the same year, led by Russia more than a dozen non-OPEC oil producers announced the reduction of production. These two production agreements have been implemented since 2017, the implementation period of 6 months.

Today, the implementation of production is nearing completion, but due to the strong recovery of US shale oil, the first half of this year, the situation of global crude oil oversupply did not show significant improvement.

Since mid-April, international oil prices have fallen by more than 13%. May 5, the international oil prices fell to around 45 US dollars a barrel, back to the end of November last year, the level of production before the release.

CICC Energy researcher Guo Zhaohui said the current market for OPEC meeting is expected to pessimistic. Although the early Saudi oil and other oil producers will extend the terms of the agreement, but the market is expected to cut the size of investors may shrink. In the last two weeks, the New York Mercantile Exchange crude oil futures speculative fund net positions fell by 16%.

Recent US disclosure of the data show that shale oil production activity, but also exacerbated the market oversight of crude oil concerns. US oil service company Baker Hughes released data show that as of 5 week, the number of US oil active drilling has increased for 16 weeks, refresh the April 2015 high since. In addition, the US crude oil production and crude oil inventories also reached a record high.

International energy research firm An Xunsi China analysis, the current price adjustment cycle, Libya two oil field to restart, the market is expected to oil supply is still excess, if the current crude oil prices, the current round of steam and diesel prices down about 245 Yuan, it is likely to hit the largest decline in the year.

This year, China has gone through eight rounds of refined oil price cycle, which three times raised, three times down, twice stranded, steam, diesel prices were down 65 yuan per ton. The largest decline in the year occurred at 24:00 on March 28, steam, diesel prices were down 230 yuan per ton and 220 yuan.

CNOOC recently released the news that the first quarter of this year, CNOOC import and export companies completed a total of 548,000 tons of refined oil processing exports, compared with 2816 tons over the same period increased by nearly 270,000 tons.
