[Effect of heavy metals on the growth of soil streptomyces].

The effect of heavy metals on the streptomycete pure cultures under solid and liquid nutrient media has been studied. There were revealed streptomycete forms sensitive and resistant to heavy metals. Streptomyces versipellis strain 1, S.

[Prospects for storing streptomycetes in atmospheres of various gases].

The possibility of Streptomyces cultures preservation in the atmosphere of argon, nitrogen, carbon dioxide and free air (the latter as a control) has been first studied. The possibility of short-term (4-6 months) preservation of Streptomyces cultures in the atmosphere of argon and nitrogen has been demonstrated. Some cultures could be preserved in the argon and nitrogen atmosphere for 26 years.
