    摘要： The present invention relates to a granular starch hydrolyzing enzyme composition comprising an acid stable alpha amylase (asAA) having granular starch hydrolyzing activity. The invention also relates to a one-step method for producing an alcohol which comprises contacting a granular starch substrate with an acid-stable alpha amylase (asAA) having granular starch hydrolyzing (GSH) activity and a glucoamylase (GA) in a fermentation step which also comprises ethanologenic microorganisms at a temperature of 25–40° C. to obtain a fermentation broth having 5 to 20% ethanol.

    摘要： A virtual ethernet interface interconnects a first computer at a customer premise with an ethernet local area network (LAN) at a central office that is connected to the customer premise via a digital subscriber line (DSL). The virtual ethernet interface comprises a virtual interface card connected to the first computer and a physical interface card connected to a second computer that is in communication with the ethernet hub. On start up, the central office computer sends the MAC address associated with the ethernet interface of the physical interface card back to the virtual interface card of the first computer. Thus, the virtual ethernet interface allows the first computer to form ethernet frames using the MAC address of the physical interface card so that it appear as though they were originated from the second computer. Further, the first computer can receive frames taken from the ethernet LAN by the physical interface card and transmitted to the virtual interface card over the DSL link.

    摘要翻译： 虚拟以太网接口将客户端的第一台计算机与通过数字用户线（DSL）连接到客户端的中心局的以太网局域网（LAN）相互连接。 虚拟以太网接口包括连接到第一计算机的虚拟接口卡和连接到与以太网集线器通信的第二计算机的物理接口卡。 启动时，中心局计算机将与物理接口卡的以太网接口相关联的MAC地址发送回第一台计算机的虚拟接口卡。 因此，虚拟以太网接口允许第一台计算机使用物理接口卡的MAC地址形成以太网帧，使其看起来好像是源自第二台计算机。 此外，第一台计算机可以通过物理接口卡接收从以太网LAN采集的帧，并通过DSL链路传输到虚拟接口卡。
