摘要： A laboratory device and method are adapted to subject a same rock sample to successive liquid treatments without any intermediary handling of the sample. The device combines a chamber comprising a first part fitted with an inlet for introducing a rock sample and liquid reagents into the chamber; a heater for regulating the temperature in the chamber and a plug fitted within an open port for protecting the chamber from an overpressure. The first part also comprises means for stirring the contents of the chamber including a liquid by introducing gas as bubbles into the liquid. A second part of the chamber is located under the first part and a selective filtering unit is interposed between the first and second parts of the chamber, the filter has a porosity selected for retaining organic material contained in the sample. A gas bubbling inlet is provided for introducing the gas into the liquid contained in the chamber and a valve controlled discharge opening is also provided for draining off liquid from the chamber.

摘要： This invention relates to the production of citric and/or isocitric acids. The production of citric and/or isocitric acids is effected by cultivating a citric and/or isocitric acid-producing yeast in a culture medium containing a compound selected from cyanoacetic acid, and organic and inorganic derivatives thereof. Increased yields of citric and isocitric acids are obtained using a process in accordance with the invention, preferably using a yeast of the genus Candida.
摘要翻译：本发明涉及柠檬酸和/或异柠檬酸的生产。柠檬酸和/或异柠檬酸的生产通过在含有选自氰基乙酸及其有机和无机衍生物的化合物的培养基中培养产生柠檬酸和/或异柠檬酸的酵母来实现。柠檬酸和异柠檬酸的产率提高是使用根据本发明的方法获得的，优选使用假丝酵母属的酵母。
