Collaboration of Microorganisms to Acquire Series of Key Biotechnology for Jatropha Production

The energy plant Jatropha curcas is a perennial woody plant of the Euphorbiaceae family and has the potential of “not competing with people for food, not competing with the grain, and not competing with the land”. Its seed oil is used to produce high-quality biofuels. High quality raw materials.

The Ye Jian Youth Research Group of the Institute of Microbiology, Chinese Academy of Sciences, established a high-efficiency plant transformation platform in the early stage, and cooperated with Temasek Life Sciences Research Institute of the National University of Singapore, Nanjing Agricultural University, and laboratories and researchers of the United States to combine production practices. Flowering traits, susceptibility to diseases and pests and other limiting factors, using biotechnology to carry out biotechnology and molecular breeding Jatropha research, made a series of progress, related results were published in Biotechnology for Biofuels and Functional & integrative genomics and other magazines.

At present, the main factor that restricts the large-scale commercial application of Jatropha curcas is the lack of genetic material with high yield and stable yield. Genetic improvement of Jatropha curcas to increase yield and resistance has become the main research direction in the world. Jatropha's main output limitation factors mainly include adverse environmental and disease hazards.

At present, the main cultivation areas of Jatropha are limited to low-altitude regions in some tropical and sub-tropical regions in China. Environmental factors such as temperature and climate factors have negative effects on the important factors such as the number of flowering time and the proportion of male and female flowers, which ultimately leads to low yields and greatly limits their The applicability of our country.

The researchers genetically improved Flowering Locus T (FT), a key genetic element of plant flowering, successfully improved the jatropha flower traits, optimized the tree type, and reduced harvesting costs and yields. The purpose of the project is to make it possible to expand the harvesting scope of Jatropha curcas, and provide new ideas for increasing production and income of other economic forests.

In response to the major virus disease pathogenic geminivirus of Jatropha curcas, the researchers designed a multi-target RNA interference strategy to target multiple viral targets and the genetically modified Jatropha obtained had a variety of geminivirus-induced diseases. Broad spectrum resistance. These two research results were published in the International Bioenergy for Biofuels (Ye, 2014, 7.19; Ye, 2014, 7.149).

Chopped Graphite/Graphite Electrode in different materials have different definition of graphite pieces, some data and literature is not very big graphite particles are called graphite pieces (such as Graphite Powder) some is graphite products have a certain size, for Graphite Broken into patches, we here say of graphite for a second, usually called graphite blocks. Graphite is produced from graphitization and machining process of graphite products. It is used as additive and conductive material in the manufacture of graphite waste in steel and foundry industries, and can also be processed according to customer's requirements. They are also widely used in electric arc furnaces (steelmaking) and electrochemical furnaces (metallurgical and chemical industries).

Main use of graphite

Graphite pieces due to its low ash content, conductive and heat conduction performance is good, so there are a wide range of USES, can be added to the formula of less ash or dust products, graphite broken broken into small particles commonly use. Ingredients to add a certain amount of graphite, the plastic paste after kneading, especially during extrusion can reduce the friction resistance paste to squeeze the mouthpiece, to improve the coefficient of pressure type. Graphite pieces of coal adsorption properties of asphalt is better, to join the carbon block can rise to reduce the "short" waste (i.e., the product after roasting top produce honeycomb structure), and can improve the thermal conductivity of the carbon block and alkali corrosion resistance. The electrode paste used in hermetically-sealed thermal furnace is added to a certain amount of graphite to increase the conductivity and thermal conductivity of the electrode paste and accelerate the sintering speed of electrode paste. When the graphite is ground into small particles or fine powder, it is also used as raw material for the production of graphite chemical equipment (such as graphite-resin tubes). The graphite can also be used as a carbon addition agent for the electric furnace.

Graphite classification

1. Raw and broken. It is a raw blank that is not qualified after molding.

2. Roasting is the cutting debris that is recovered after the roasting of raw billet and after inspection of unqualified waste and the processing of calcined products.

3. The graphite is broken, and it is inspected by the graphite-producing waste and the cutting debris produced by graphite products in the process of processing.
