摘要： Disclosed is a method and apparatus for the extraction of high molecular weight biopolymers from plants. Specifically, invention described herein relates to the commercial processing of plant material, including that from desert plants native to the southwestern United States and Mexico, such as the guayule plant (Parthenium argentatum), for the extraction of biopolymers, including natural rubbers. More specifically, the invention relates to laboratory to commercial scale extraction of high molecular weight biopolymers from plant materials including the chemical and mechanical processing of the plants and purification of the extracted biopolymer.

摘要： The present disclosure provides for a method of rapid expanded solvent extraction of biopolymers, such as rubber, from plant materials, such as guayule, using an expanded hexane solvent. As is illustrated herein, the use of the expanded hexane solvent results in a markedly more efficient and rapid extraction process over other supercritical carbon dioxide extraction systems, including those systems using a hexane cosolvent.

摘要： The present disclosure provides for a formula and process for making elastomeric rubber thin film articles. In particular, the formula and process is a system which produces non-Hevea or Guayule natural rubber latex (GNRL) thin film articles which have a thickness of 30-80 microns (0.03-0.08 mm), and preferably less than 40 microns (0.04 mm). These thin film articles exhibit physical strength properties similar to that of Hevea brazilensis natural rubber latex (NRL). More specifically, the disclosed thin rubber thin film articles exhibit unaged tensile strength of at least 24 MPa (about 3500 psi) and aged tensile strength of at least 19 MPa (about 2800 psi).

摘要： Transgenic guayule lines were created by constitutively expressing transgenes that encode for prenyltransferase and allylic diphosphate synthase. These new lines are important to rubber production because they result in plants that produce latex rubber which is lower in guayulin, a compound that produces a skin irritation in some animals. Controlling prenyltransferase production also permits the control of the production of resin by the plants, which has important industrial implications. Additionally, prenyltransferase manipulation can result in latex particles of different size, containing rubber of different molecular weight, which is also significant to industrial production. Although the elevated prenyltransferase activity in the transgenic lines resulted in shorter rubber molecules, the number of rubber molecules made by these transgenic lines was increased.
摘要翻译： 通过组成型表达编码异戊烯基转移酶和烯丙基二磷酸合成酶的转基因产生转基因鱼粒系。 这些新生产线对于橡胶生产很重要，因为它们产生了生产乳胶的植物，其在瓜亚豆林中较低，这是在一些动物中产生皮肤刺激的化合物。 控制异戊烯转移酶的生产也可以控制植物对树脂的生产，这具有重要的工业意义。 此外，异戊烯转移酶操作可以产生不同尺寸的胶乳颗粒，其含有不同分子量的橡胶，这对于工业生产也是重要的。 尽管转基因株系的异戊烯基转移酶活性升高导致较短的橡胶分子，但由这些转基因品系制成的橡胶分子的数量增加。

摘要： A method for the extraction, separation, fractionation and purification of biopolymers from plant materials using supercritical and/or subcritical solvent extractions is disclosed. Specifically, the process can be used for the separation of resins and rubber from guayule shrub (Parthenium argentatum), and other rubber and/or resin containing plant materials, using supercritical solvent extraction, for example supercritical carbon dioxide extraction. Additionally, polar and/or non-polar co-solvents can be used with supercritical carbon dioxide to enhance the selective extraction of resins and rubbers from the shrub.
