Two Cell-Bound Keratinases of Trichophyton Mentagrophytes
Two cell-bound keratinases, II and III, of Trichophyton mentagrophytes were extracted from mycelium and purified. The purified keratinases, II and III, had a specific keratinolytic activity of 36.4 and 39.4 KU/mg respectively. The molecular weights of keratinases II and III were 440,000 and 20,300 respectively. Immunodiffusion analysis showed that these two cell-bound keratinases, II and III, were not identical to each other nor to extracellular keratinase I of the same species
Internet over the VDL-2 Subnetwork: the VDL-2/IP Aviation Datalink System
This report describes the design to operate the standard Internet communications protocols (IP) over the VHF aviation Data Link Mode 2 (VDL-2) subnetwork. The VDL-2/IP system specified in this report can operate transparently with the current aviation users of VDL-2 (Airline Communications and Reporting System, ACARS and Aeronautical Telecommunications Network, ATN) and proposed users (Flight Information Service via Broadcast, FIS-B). The VDL-2/IP system provides a straightforward mechanisms to utilize inexpensive, commercial off-the-shelf (COTS) communications packages developed for the Internet as part of the aviation datalink system
