This study demonstrated that the aerobic granules cultivated by seeding activated sludge into column-type sequential batch reactors and fed with synthetic wastewater at organic loading rate of 1.5kg/m3-d can be dried by acetone gradient method to moisture content less than 1%. Then, the dried granules can be reactivated through a re-cultivation process to recover their organic degradation capacity in 12h, or their appearance in 5d. During the drying and recovery, the granules experienced volume and weight losses by >80% and >85%, respectively, with minimal loss in structural integrity. The microbial communities of the dried and re-cultivated granules were probed using polymerase chain reaction-denaturing gradient gel electrophoresis technique. The family Xanthomonadaceae and the family Comamonas can survive in dried granules and could contribute to maintain structural integrity in re-cultivation stage. ? 2013 Elsevier Ltd.DryingMicrobial communityRe-cultivationStructural stability[SDGs]SDG11journal article10.1016/j.biortech.2012.12.1782-s2.0-84873712543https://www.scopus.com/inward/record.uri?eid=2-s2.0-84873712543&doi=10.1016%2fj.biortech.2012.12.178&partnerID=40&md5=45f645d8c2859289bbb9f39b8678f775
