Abstract: Plasmids for the high-level expression of bovine growth hormone in yeast and in E. coli are described, as are processes for the production of bovine growth hormone which utilize host cells transformed with the expression vectors.

Abstract: High protein content feed or hormonal steroids have been added to fish feed in order to elevate the efficiency of the feed. However, the steroids remain in the fish and may be detrimental to those who eat the fish. The invention relates to a method for the production of salmon growth hormone, which enhances the efficiency of the feed without the above side effects, using a synthetic gene in yeast or E. coli. It has been found that salmon growth hormone may be produced economically and in bulk in yeast or E. coli by gene manipulation technology.

Abstract: A tubular high-temperature storage cell is provided. This cell comprises a central rod electrode of one polarity and a second electrode which encases said central electrode. Between both electrodes, a large separator is interposed. One electrical terminal from the central rod electrode is provided at the center of the cell top through a feedthrough sleeve. The opposite terminal is welded directly to the cell container can or to the cell top lid. The cell container itself also can act as a current collector.
