Strain JC669 T was isolated from a oating island of Loktak lake, Manipur, India and shared highest 16S rRNA gene sequence identity with Aquisphaera giovannonii OJF2 T . The strain is an aerobe, Gram-stainnegative, yellowish orange coloured, non-motile, NaCl intolerant, spherical to oval shaped, grows in single or aggregates and produce structures which appear like fruiting bodies. Strain JC669 T grows well up to pH 9.0, has MK6 as respiratory quinone, C 18:1 ω9c, C 16:0 and C 18:0 as major fatty acids and phosphatidylcholine, an unidenti ed amino lipid, an unidenti ed choline lipid (UCL) and six unidenti ed lipids (UL1,2,3,4,5,6) as polar lipids. The genome size of strain JC669 T is 10.04 Mbp and genomic G+C content of 68.5 mol%. Based on phylogenetic, polyphasic including genomic analyses support strain JC669 T as a novel species of the genus Aquisphaera, for which we propose the name Aquisphaera insulae sp. nov. Type strain is JC669 T ( =KCTC 72672 T = NBRC 114306 T ).

Two axenic cultures of Planctomycetota were isolated from distinct geographical locations of India. Strain JC665 T was isolated from a rhizosphere soil of Loktak lake, Manipur, whereas strain JC747 was isolated from a sediment located at Pallikkara village, Kerala, India. The two closely related strains shared the highest (94.6%) 16S rRNA gene sequence identity with Paludidphaera borealis PX4 T , while the 16S rRNA gene sequence identity between both strains was 100%. Both strains grow aerobically, stain Gram negative, colonies are light pink-coloured, cells are non-motile, spherical to oval-shaped and tolerate NaCl up to 2% (w/v). While strain JC665 T grows well up to pH 9.0, strain JC747 up to pH 8.0. Respiratory quinone for both strains was MK-6. C 16:0 , C 18:1 ω9c and C 18:0 are the major fatty acids.Phosphatidylcholine, two unidenti ed glycolipids, seven unidenti ed lipids and two unidenti ed phospholipid was the polar lipid composition of both strains. Both strains have genome size of about 8.0Mb and have GC content of 66.4 mol%. Both strains contained genes encoding for lycopene related carotenoids. The phylogenetic position, morphological, physiological and genomic features support the classi cation of strain JC665 T as a new species of the genus Paludisphaera, for which we propose the name Paludisphaera rhizosphaerae sp. nov. Strain JC665 T (= KCTC 72671 T = NBRC 114305 T ) and JC747 are the type and non-type strain of the new species, respectively.

The 3.52-Mbp whole-genome sequence of a Glutamicibacter sp. strain isolated from soil sediment of the floating islands of Loktak Lake is reported. The genomic information here gives insight into the presence of genes linked to oxidative stress, osmo-protection, and cold shock proteins which helps in the survival of the organism under extreme environmental conditions.
