    摘要: Crude solid vanillin-containing material is precipitated from a solution obtained by biotransformation, and purified by a process comprising contacting it with a purification fluid selected from (a) a liquefied gas whose pressure exceeds its critical pressure and whose temperature is below its critical temperature; (b) a supercritical fluid; (c) a gas. The fluid is preferably liquid carbon dioxide. The temperature is maintained below 25°. The product may be further purified by treatment with CO2 in a fluid bed drier. The crude material is preferably one precipitated from a solution resulting from biotransformation of ferulic acid. A new strain of Amycolatopsis capable of generating high concentrations of vanillin with minimal odoriferous by-products (e.g. guaiacol) is also disclosed.

    摘要: An access system that is coupled to a communication network hosts a file for an end-user system. The access system receives the file from the end-user system. The access system stores the file in a memory in the access system. The access system receives a message from the communication network, wherein the message requests the file from the end-user system. In response to the message, the access system determines if the file may be transferred to the communication network from the memory in the access system. If the file may be transferred to the communication network from the memory in the access system, then the access system notifies the end-user system that the file will be transferred from the memory in the access system to the communication network and transfers the file from the access system to the communication network.
