To investigate biological effects of space flight on several conditional pathogenic bacteria and biodestructive fungi.
Several potentially pathogenic or biodegrading microorganisms, including bacteria, actinomyces and fungi, were carried on-board spacecraft for 7 d. Some of the biological characteristics were studied by using general microbial test technology after recovery.
In space condition, survival and growth rate were promoted, and soluble pigments were produced, while morphological properties were changed differently. The antibiotic-sensitivity of certain strains decreased, while most of them showed no changes.
The reproduction ability and growth rate of these microorganisms are promoted after being carried into space, and morphological differentiation increase. The resistance to antibiotics is stable.
研究太空飞行对几种条件致病细菌和生物破坏性真菌的生物学效应。
将包括细菌、放线菌和真菌在内的几种潜在致病或生物降解微生物搭载航天器7天。回收后采用常规微生物检测技术研究其部分生物学特性。
在太空条件下，微生物的存活和生长速率提高，产生了可溶性色素，形态特性发生了不同程度的变化。某些菌株的抗生素敏感性降低，而大多数菌株无变化。
这些微生物被带入太空后，繁殖能力和生长速率提高，形态分化增加，对抗生素的抗性稳定。
