title: [Study of the possibility of stabilizing a levorin microbiological standard].
abstract: The effect of a number of factors, providing increased stability of the levorin microbiological standard was studied. It was shown that air-tight packing and inert gas atmosphere (antibiotic storage in ampoules sealed under nitrogen) significantly increased the antibiotic stability. It was also shown that hydrochinone had the highest positive effect on levorin stability.
