Abstract

In consistence with conception of using microbial technology for plant growing/protosoil formation for Lunar/Martian greenhouses (Kozyrovska et al., 2004-2010), we anticipate microbes to alleviate impact of the environmental stressors on plant development. Bacteria can augment physiological processes in plants, for example, photosynthesis, by regulating a hormone level and decreasing glucose sensing in planta (Zhang et al., 2008). The study aimed to examine impact of consortium of well-defined bacteria Klebsiella oxytoca IMBG26 and Paenibacillus sp. IMBG150 on the CAM-plantlets Kalanhoe diagramontiana and Kalanhoe tubiora pho- tosynthetic activity after acute action of gamma radiation (60Co), Near Martian ultraviolet radiation, low pressure (100 mbar), and high concentrations of CO2 (95Plantlets of K. tubi-ora were exposed to harmful doses of Near Martian UV radiation for 3 hours (26.53 J/cm2). A week before experiment kalanchoe plantlets were subjected to acute effects of ionizing radiation at doses of 30 and 70 Gy. In noninoculated plantlets after 30 Gy the photosynthetic activity fell to 71.
