【摘要】：目的研究空間條件下幾株條件致病菌及生物降解真菌的生物學(xué)效應(yīng)。方法可能影響航天員身體健康及降解空間材料的幾株微生物,包括細(xì)菌、真菌、放線菌,經(jīng)搭載7d后,應(yīng)用常規(guī)微生物檢驗(yàn)技術(shù)對它們的一些生物學(xué)特性進(jìn)行初步研究。結(jié)果空間條件下菌株的存活率有明顯提高,普遍生長較快,多數(shù)菌株產(chǎn)生色素;形態(tài)特征也有不同程度的變化;某些菌株對個(gè)別藥物的抗性有所減弱,對多數(shù)藥物的抗性不變。結(jié)論微生物在空間條件下繁殖能力增強(qiáng),搭載后生長加快,形態(tài)分化提前,對藥物的抗性基本穩(wěn)定。
[Abstract]:Objective to study the biological effects of several opportunistic pathogens and biodegradable fungi under space conditions. Methods several microbes, including bacteria, fungi and actinomycetes, which may affect the health of astronauts and degrade space materials, were carried for 7 days. Some of their biological characteristics were preliminarily studied by using the conventional microorganism test technique. Results the survival rate of the strains increased obviously under the space condition, and the growth rate was relatively fast, and most of the strains produced pigments. The resistance of some strains to individual drugs was weakened, but the resistance to most of the drugs remained unchanged. Conclusion the ability of microbes to reproduce under spatial conditions is enhanced, the growth rate is accelerated after loading, and the morphological differentiation is advanced. The resistance to drugs was basically stable.
