“…For Q. citrea RE35F/1 T , the genomic length was calculated as 3,031,321 bp consisting of 2,971 predicted coding genes with a DNA G+C content of 64.2 mol%, whereas the genome size of strain Q. flava SW-46 T was 3,229,668 bp in which the DNA G+C contents of both strains were 63.6 mol% and 3,156 predicted coding genes. The DNA G+C contents of three type strains all fell within the range of 60.5-66.8 mol% for members of the genus Qipengyuania [16][17][18][19]. Due to the close phylogenomic relationship between strains strain ABI-127-1 and Q. flava SW-46 T and Q. citrea RE35F/1 T , the genomes of the three type strains were compared.…”

“…Among the 19 currently validated members of Erythrobacteraceae, the genus Qipengyuania was first described in 2015, with the species type Qipengyuania sediminis [16]. Currently, the genera comprises 31 valid type species (https://lpsn.dsmz.de/genus/qipengyuania, accessed on 6 June 2023) isolated from various habitats [17][18][19]. It may indicate that this genus may be widely distributed in coastal environments like the Roseobacter lineage [20].…”

Phycosphere niches host rich microbial consortia that harbor dynamic algae–bacteria interactions with fundamental significance in varied natural ecosystems. Hence, culturing the uncultured microbial majority of the phycosphere microbiota is vital for deep understanding of the intricate mechanisms governing the dynamic interactions, and also to provide novel and rich microbial resources, and to discover new natural bioactive metabolites. Synechococcus elongatus PCC 7942 is a robust model cyanobacterium widely used in environment, synthesis biology, and biotechnology research. To expand the number of novel phycosphere species that were brought into culture and to discover the natural bioactivities, we presented a new yellow-pigmented bacterium named ABI-127-1, which was recovered from the phycosphere of PCC 7942, using an optimized bacterial isolation procedure. Combined polyphasic taxonomic and phylogenomic characterization was performed to confidently identify the new isolate as a potential novel species belonging to the genus Qipengyuania. The observed bioactivity of strain ABI-127-1 with promoting potential towards the growth and CO2 fixation efficiency of the host microalgae was measured. Additionally, the bacterial production of active bioflocculant exopolysaccharides was evaluated after culture optimization. Thus, these findings revealed the potential environmental and biotechnological implications of this new microalgae growth-promoting bacterium isolated from the phycosphere microenvironment.

Qi.pen.gyu.an'i.a. N.L. fem. n. Qipengyuania , named after Qipeng Yuan, a Chinese biologist, who has achieved excellent accomplishments in biopharmaceuticals, natural product research and development, genetic engineering drugs, etc. Pseudomonadota / Alphaproteobacteria / Sphingomonadales / Sphingomonadaceae / Qipengyuania The genus Qipengyuania , belonging to the family Sphingomonadaceae , order Sphingomonadales , class Alphaproteobacteria , and phylum Pseudomonadota , currently includes 30 species with validly published names. Cells are Gram‐stain‐negative, non‐spore‐forming, rod, spherical, or pleomorphic cocci. Aerobic or facultatively aerobic chemoorganotrophs. Slightly halophilic or halotolerant, mostly grow well in the salinity range of 0–14.0% (w/v) NaCl, with the optimum of 1.0–5.0%. Grow at pH range from 4.0 to 11.0, with an optimum at pH 6.5–9.0. Mesophilic, optimal growth at 20–37°C, growth range 4–45°C. The colony color is yellow, orange, or light green. Cells contain carotenoid pigments but not bacteriochlorophyll a . The major isoprenoid quinone is ubiquinone‐10. The main fatty acids mostly detected are hexadecenoic acid (C 16:1 ), heptadecenoic acid (C 17:1 ), and octadecenoic acid (C 18:1 ). The major polar lipids are diphosphatidylglycerol (DPG), phosphatidylethanolamine (PE), and phosphatidylglycerol (PG). The DNA G + C content is 60.1–66.8 mol% (by genome sequence). The known habitats are aquatic environments such as hot springs, seawater, mangrove soil, and marine invertebrates as well as distributed in subterrestrial sediment. DNA G + C content (mol%) : 60–67 (by genome). Type species : Qipengyuania sediminis Feng et al. 2015 VP , emend. Xu et al. 2020.
