Abstract: Methods, processes and materials for the production and recovery of Tiacumicins produced by culturing a microorganism belonging to the species Dactylosporangium aurantiacum subspecies hamdenensis having the ability to produce and accumulate one or more Tiacumicin in a nutrient medium comprising a carbon source, a nitrogen source, trace elements such as inorganic salts, and an adsorbent, wherein said nitrogen source comprises fish powder, and wherein said Tiacumicin is produced in a yield greater than about 50 mg/L broth.

Abstract: A ferromagnetic memory cell is disclosed. The cell includes a bit (10), made of a ferromagnetic material, having a remnant polarity. The cell also includes a read drive line (20) coupled to a first portion of the bit (10), to feed a current into the bit (10). A sense conductor (30) is coupled to a second portion of the bit (10), to receive the current from the bit (10). The current conducted through the bit (10) is responsive to the polarity of the bit (10). A method is also disclosed for determining the magnetic polarity of a ferromagnetic bit (10). In this method, a bit (10) is provided that is made of ferromagnetic material and has a remnant polarity. An input current (50) is fed into the bit (10) through a read drive line (20) coupled to a first portion of the bit (10). An output current (60) is received from the bit (10) through a sense conductor (30) coupled to a second portion of the bit (10). The current conducted through the bit (10) is responsive to the polarity of the bit (10).
