Introduction
Carboncyclingisacriticalprocessintheearth'secosystem.Microbesplayessentialrolesincarboncyclingthroughcarbonfixation,respiration,andheterotrophicconsumptionoforganicmatter(Falkowskietal.,2008).Microbialcommunitiesshowahighdegreeoffunctionaldiversity,geography,andenvironmentalalteration,leadingtotheneedforacomprehensiveunderstandingofmicrobialcarboncyclinganditsecologicalsignificance.Recently,thefunctionalgene-basedapproachandmicrobialcarbon-cyclingmolecularecologyresearchhavemadegreatprogressinanalyzingthecarboncyclingfunctionofmicrobialcommunities,theroleofmicrobesinecosystems,andtheirresponsestoenvironmentalchanges.
