Plant synthetic intermediates
Thirty years after the production of the first generation of genetically modified plants we are now set to move into a new era of recombinant crop technology through the application of synthetic biology to engineer new and complex input and output traits. The use of synthetic biology technologies will represent more than incremental additions of transgenes, but rather the directed design of completely new metabolic pathways, physiological traits, and developmental control strategies. The need to enhance our ability to improve crops through new engineering capability is now increasingly pressing as we turn to plants not just for food, but as a source of renewable feedstocks for industry. These accelerating and diversifying demands for new output traits coincide with a need to reduce inputs and improve agricultural sustainability. Faced with such challenges, existing technologies will need to be supplemented with new and far-more-directed approaches to turn valuable resources more efficiently into usable agricultural products.VIDEO ON THE TOPIC: Synthetic plant products for industry - Rob Edwards

The regulation covers wastewater discharges from more than 1, chemical facilities. The OCPSF category includes more than 1, chemical facilities producing over 25, end products, such as benzene, toluene, polypropylene, polyvinyl chloride, chlorinated solvents, rubber precursors, rayon, nylon, and polyester.
Some plants produce chemicals in large volumes through continuous chemical processes, while others produce only small volumes of "specialty" chemicals through batch chemical processes. EPA began a new rulemaking in to address wastewater discharges from facilities that manufacture chlorine and certain chlorinated hydrocarbons CCH. The Agency collected data on CCH facilities through , and following a review of the information it discontinued the rulemaking in EPA conducted a study of regenerated cellulose manufacturers, focusing on discharges of carbon disulfide CS2.
Cellulose products manufacturers use CS2 in the viscose process to break down aged alkali cellulose prior to regeneration. Current effluent guidelines do not cover CS2 discharges. The latter two categories had been promulgated in and then withdrawn pursuant to litigation.
Development Document Describes industry processes, pollutants generated, available control and treatment technologies, the technical basis for the final rule, and costs of the rule.
Synthetic biology strategies for microbial biosynthesis of plant natural products
Photosynthesis is the process by which plants, some bacteria and some protistans use the energy from sunlight to produce glucose from carbon dioxide and water. This glucose can be converted into pyruvate which releases adenosine triphosphate ATP by cellular respiration. Oxygen is also formed. The conversion of usable sunlight energy into chemical energy is associated with the action of the green pigment chlorophyll.
Associate Editor: P. Hanson Beilstein J. This review which is the second in this series summarises the most common synthetic routes as applied to the preparation of many modern pharmaceutical compounds categorised as containing a six-membered heterocyclic ring. The reported examples are based on the top retailing drug molecules combining synthetic information from both scientific journals and the wider patent literature.

Certain plants—including the important crops sugarcane and corn maize , as well as other diverse species that are thought to have expanded their geographic ranges into tropical areas—have developed a special mechanism of carbon fixation that largely prevents photorespiration. The leaves of these plants have special anatomy and biochemistry. In particular, photosynthetic functions are divided between mesophyll and bundle-sheath leaf cells. The carbon-fixation pathway begins in the mesophyll cells, where carbon dioxide is converted into bicarbonate, which is then added to the three-carbon acid phosphoenolpyruvate PEP by an enzyme called phosphoenolpyruvate carboxylase.
Saponins are widely distributed plant natural products with vast structural and functional diversity. They are typically composed of a hydrophobic aglycone, which is extensively decorated with functional groups prior to the addition of hydrophilic sugar moieties, to result in surface-active amphipathic compounds. The saponins are broadly classified as triterpenoids, steroids or steroidal glycoalkaloids, based on the aglycone structure from which they are derived. The saponins and their biosynthetic intermediates display a variety of biological activities of interest to the pharmaceutical, cosmetic and food sectors. Although their relevance in industrial applications has long been recognized, their role in plants is underexplored.

Plant-based chemistry uses biomass resources as an alternative to fossil resources for the manufacturing of products and materials. Plant-based chemistry is a branch of chemistry in which biomass wholly or partially replaces fossil resources oil, natural gas and coal to manufacture products. It is thus possible to use biomass to manufacture biobased products and materials of varying degrees of sophistication, such as:. Plant-based chemistry can also use co-products, i. The search for optimum use of biomass in an integrated system has led to the creation of biorefineries.
Type III PKSs are associated with the production of chalcones , a class of organic compounds found mainly in plants as natural defense mechanisms and as synthetic intermediates. CHS catalysis serves as the initial step for flavonoid biosynthesis. Flavonoids are important plant secondary metabolites that serve various functions in higher plants. These include pigmentation, UV protection, fertility, antifungal defense and the recruitment of nitrogen-fixing bacteria.

The formaldehyde plant of the Intermediates division at the Verbund site Ludwigshafen looks back on years of history. As an important Core Verbund plant, the formaldehyde plant reliably and steadily supplies many plants at the Verbund site Ludwigshafen with aqueous formaldehyde solution. Every day, the plant produces a quantity that fills the equivalent of about 60 rail tank wagons. Instead of using the train, though, the product reaches internal customers via an extensive pipeline system that is 15 kilometers 9.

Вернувшись к телу мертвой матери, Николь заметила, что ее груди полны молока. Смерть явно наступила недавно. Николь приподняла тело, посадив убитую на землю. Поддерживая ее, Николь приложила девочку к материнской груди и убедилась, что ребенок сосет.
Малышка была голодна. Посреди кормления бомба осветила черты убитой - то самое лицо, которое Николь видела на картине октопауков на Площади Художников. "Вот уж не думала", - удивилась Николь.
"Быть может, я не сумею помочь, но по крайней мере буду знать, что хотя бы пыталась это сделать". Особенно тихо Николь шла по коридору: она не хотела будить Патрика и Наи, ночевавших в комнате Элли после того, как с ней приключился приступ. "Они сразу же уложат меня в постель".
