航天器AIT中心典型霉菌形态及其消杀效果研究

航天器总装厂房是航天器携带微生物的重要环境来源之一，厂房内的微生物检测与鉴定及其杀菌方法研究对于航天器的微生物安全与防控技术研究具有重要意义。本文报道了航天器AIT中心分离的青霉属、曲霉属和枝孢霉属等8个种属的典型霉菌菌落和孢子形态，为航天器霉菌鉴定和菌种库的构建提供了参考；同时研究了消毒剂、UVC辐照和热处理对这些霉菌的消杀效果，以期为航天器的霉菌防控技术研究提供科学依据。研究结果表明不同种属霉菌对3种消杀方法的敏感性具有较大的差异性。结合我国不同地区AIT中心霉菌种属的多样性，在进行我国AIT中心霉菌的消杀工作时应有针对性地科学选择不同消杀方法或综合应用多种消杀方法。

Morphological Characterization and Disinfection Effect on Typical Mould Isolated From Spaceflight AIT Center

Spaceflight AIT center is one of the important environmental sources of spacecrafts carrying microorganisms. Therefore, the research of microorganism identification and its disinfection methods are of great importance for developing techniques to prevent and control of mould contamination of spacecrafts. This study reports the typical fungal colonies and spores morphology of eight species isolated from the spacecraft AIT center, including Penicillium sp, Aspergillus sp, Cladosporium sp etc, which provids reference for mold identification and the construction of strain bank. The disinfection effects of disinfectants, UVC irradiation and heat treatment on those moulds are then studied, so as to provide scientific evidence for prevention and control of mold technology for spacecrafts. The results show that the sensitivity of fungi with different species to the three disinfection methods has great differences. Combined with the diversity of AIT central fungi species in different regions of China, we should select different disinfection methods scientifically or apply multiple methods when carrying out the disinfection work at AIT central.
