摘要
目的探讨空间环境对微生物功能性状的可能影响。方法采用空间搭载和地面对照实验的3种真菌作为霉腐实验标准菌,对9种航天器材的板材进行7个月的霉腐测试实验。结果空间搭载菌株与地面对照相比,搭载的烟曲霉菌株气生菌丝生长良好,分生孢子生长丰茂,霉腐板材重量损失较少。结论微生物在空间条件下繁殖能力增强,搭载后生长加快,形态分化提前,对材料的霉腐能力有所下降。
Objective To explore possible effect of microflora on space materials under space conditions. Method A seven months＇ biodestructive test of three fungi strains on 9 space structural materials was carried out in space environment with ground controls. Result As compared with ground control, aerial hyphae of Aspergillus grew better. In space its conidium got more abundant, and the weight loss of the materials by corrosion was less. Conclusion Reproductive ability of the fungi is enhanced under space condition. The growth rate is increased. The morphological differentiation is advanced and the biodestructive ability on space materials is somewhat reduced.
