Abstract: 5'-Inosinic acid was industrially produced using a Brevibacterium ammoniagenes mutant MW 2369 (KAIST 850214-15612) having the properties or requirements of adenine stimulation of growth by addition of guanine and Xanthine, high salvage synthetic ability and modified membrane permeability. This non-sensitive strain, MW 2369 of manganese, was mutagenized with dimethylsulfate to isolat mutant strain HW 2369 having modified permeability. The mutant strain MW 2369 grew well on a minimal medium and showed little growth on a minimal medium supplemented with lysozyme 50 μg/ml.  MW 2396 produced 5'-Inosinic acid 58.4 g/l under optimal conditions of fermentation.

Abstract: The  motor  control  method  compensates  the   accumulative tolerance of the zoom lenses for  getting  the  fine  images.  The accumulative tolerance caused by the deviation of the  lense  axis between the tele-mode and the  wide-mode  can  be  compensated  by having the drive motor of the zoome lenses reversed  for  a  while after finishing the tele-mode operation.
