Influence of Space-Flight Factors on the Properties of Microorganisms, Producers of Biologically Active Substances

The following substances were isolated under the influence of space-flight factors in cosmic experiments aboard the Mirorbital station: an MIB-90 monoisolant, which is distinguished by its morphological and biochemical properties and enhanced productivity, was isolated from the Bacillus thuringiensis ssp. Kurstaki var. Z-52culture, which is a producer of the plant protection agent Lepidocide; and MIA-74 and MIP-89 monoisolants, which are highly active toward heavy petroleum fractions (C₂₃–C₃₃), were isolated from the Arthrobacter OC-1culture, which is a producer of biodegradants for petroleum.
