A slow growing, heat resistant bacterium, identified by 16S rRNA gene sequencing as Microbispora sp., was recovered from the wreckage of the ill-fated space shuttle Columbia (STS-107). As this organism survived disintegration of the space craft, heat of reentry, and impact, it supports the possibility of a natural mechanism for the interplanetary spread of life by meteorites.
一种生长缓慢、耐热的细菌,经16S rRNA基因测序鉴定为小双孢菌属(Microbispora sp.),从不幸坠毁的哥伦比亚号航天飞机(STS - 107)残骸中分离出来。由于这种生物在航天器解体、重返大气层的高温及撞击中存活了下来,它为生命通过陨石进行行星际传播的自然机制提供了可能性。
