Potential utilization of terrestrially derived dissolved organic matter by aquatic microbial communities in saline lakes
2020
Overview
Lakes receive large amounts of terrestrially derived dissolved organic matter (tDOM). However, little is known about how aquatic microbial communities interact with tDOM in lakes. Here, by performing microcosm experiments we investigated how microbial community responded to tDOM influx in six Tibetan lakes of different salinities (ranging from 1 to 358 g/l). In response to tDOM addition, microbial biomass increased while dissolved organic carbon (DOC) decreased. The amount of DOC decrease did not show any significant correlation with salinity. However, salinity influenced tDOM transformation, i.e., microbial communities from higher salinity lakes exhibited a stronger ability to utilize tDOM of high carbon numbers than those from lower salinity. Abundant taxa and copiotrophs were actively involved in tDOM transformation, suggesting their vital roles in lacustrine carbon cycle. Network analysis indicated that 66 operational taxonomic units (OTUs, affiliated with
Alphaproteobacteria
,
Actinobacteria
,
Bacteroidia
,
Bacilli
,
Gammaproteobacteria
,
Halobacteria
,
Planctomycetacia
,
Rhodothermia
, and
Verrucomicrobiae
) were associated with degradation of CHO compounds, while four bacterial OTUs (affiliated with
Actinobacteria, Alphaproteobacteria, Bacteroidia and Gammaproteobacteria
) were highly associated with the degradation of CHOS compounds. Network analysis further revealed that tDOM transformation may be a synergestic process, involving cooperation among multiple species. In summary, our study provides new insights into a microbial role in transforming tDOM in saline lakes and has important implications for understanding the carbon cycle in aquatic environments.
