High-quality draft genome sequence of Aquidulcibacter paucihalophilus TH1-2 T isolated from cyanobacterial aggregates in a eutrophic lake.

Aquidulcibacter paucihalophilus TH1-2T is a member of the family Caulobacteraceae within Alphaproteobacteria isolated from cyanobacterial aggregates in a eutrophic lake. The draft genome comprises 3,711,627 bp and 3489 predicted protein-coding genes. The genome of strain TH1-2T has 270 genes encoding peptidases. And metallo and serine peptidases were found most frequently. A high number of genes encoding carbohydrate active enzymes (141 CAZymes) also present in strain TH1-2T genome. Among CAZymes, 47 glycoside hydrolase families, 37 glycosyl transferase families, 38 carbohydrate esterases families, nine auxiliary activities families, seven carbohydrate-binding modules families, and three polysaccharide lyases families were identified. Accordingly, strain TH1-2T has a high number of transporters (91), the dominated ones are ATP-binding cassette transporters (61) and TonB-dependent transporters (28). Major TBDTs are Group I, which consisted of transporters for various types of dissolved organic matter. These genome features indicate adaption to cyanobacterial aggregates microenvironments.
