Abstract
Two Gram-stain-negative bacterial strains, S13-6-6 and S13-6-22T, were isolated from sediment sample collected at a water depth of 4 m from Lake Hongze, Jiangsu Province, PR China. The cells of strains S13-6-6 and S13-6-22T were non-spore-forming, aerobic, non-motile and formed orange colonies on R2A agar. Comparative 16S rRNA gene sequence studies revealed a clear affiliation of the two strains with he phylum Bacteroidota, and revealed the highest pairwise sequence similarities with Lacibacter daechungensis H32-4T (97.8 %), Lacibacter cauensis NJ-8T (97.8 %), Lacibacter luteus TTM-7T (97.4 %) and Lacibacter nakdongensis SS2-56T (97.4 %). The results of phylogenetic analysis based on 16S rRNA gene sequences indicated that the strains formed a clear phylogenetic lineage with the genus Lacibacter. The major fatty acids were identified as iso-C15 : 1G, iso-C15 : 0, iso-C17 : 0 3-OH and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) (>10 %), and the respiratory quinone was identified as menaquinone MK-7. The polar lipids consisted of phosphatidylethanolamine, two unidentified aminolipids, an unidentified phospholipid and six unidentified lipids. The genomic DNA G+C content was determined to be 40.2 mol% (HPLC) for strain S13-6-6 and 40.3 % (genome) for strain S13-6-22T. The combined genotypic and phenotypic data indicated that strains S13-6-6 and S13-6-22T represent a novel species of the genus Lacibacter, for which the name Lacibacter sediminis sp. nov. is proposed. The type strain is S13-6-22T (=CGMCC 1.17450T =JCM 35802T).

Abstract
A yellow, Gram-stain-positive, strictly aerobic, thermotolerant, non-motile and rod-shaped bacterial strain, designated RY-1T, was isolated from a silt sample of Fuyang River, Wuqiang County, Hengshui City, Hebei Province, PR China. Cells showed oxidase- and catalase-positive activities. Growth occurred at 20-45 °C (optimum, 37 °C) and pH 6.0-8.0 (optimum, pH 7.0), and in the presence of 0-1.5 % (w/v) NaCl (optimum, 0%). A phylogenetic tree based on 16S rRNA gene sequences revealed that strain RY-1T formed a phylogenetic lineage with Flavihumibacter members within the family Chitinophagaceae. A comparison of 16S rRNA gene sequences showed that strain RY-1T was most closely related to Flavihumibacter cheonanensis WS16T (98.6 %), Flavihumibacter sediminis CJ663T (97.7 %) and Flavihumibacter solisilvae 3-3T (97.6 %). The genome size of strain RY-1T was 4.71 Mb, and the DNA G+C content was 44.3 %. The average nucleotide identity, digital DNA-DNA hybridization and average amino acid identity values between strain RY-1T and reference strains were all lower than the threshold values for species delineation. Strain RY-1T contained menaquinone-7 and iso-C15 : 0, iso-C17 : 0 3-OH and iso-C15 : 1G as the sole respiratory isoprenoid quinone and major cellular fatty acids (≥5 %), respectively. The major polar lipids consisted of phosphatidylethanolamine, three unidentified aminolipids and four unidentified lipids. According to the results of phenotypic, phylogenetic and chemotaxonomic characteristics, strain RY-1T represents a novel species of the genus Flavihumibacter, for which the name Flavihumibacter fluminis sp. nov. is proposed. The type strain is RY-1T (=GDMCC 1.2775T=JCM 34870T).

Reactivation of Frozen Stored Microalgal-Bacterial Granular Sludge under Aeration and Non-Aeration Conditions. WATER 2021.

Abstract
In this paper, reactivation of microalgal-bacterial granular sludge (MBGS) stored at −20 °C for 6 months was investigated under respective aeration (R1) and non-aeration (R2) conditions. Results showed that the granular activity could be fully recovered within 21 days. The average removal efficiency of ammonia was higher in R1 (92.78%), while R2 showed higher average removal efficiencies of organics (84.97%) and phosphorus (85.28%). It was also found that eukaryotic microalgae growth was stimulated under aeration conditions, whereas prokaryotic microalgae growth and extracellular protein secretion were favored under non-aeration conditions. Sequencing results showed that the microbial community underwent subversive evolution, with Chlorophyta and Proteobacteria being dominant species under both conditions. Consequently, it was reasonable to conclude that the activity and structure of frozen stored MBGS could be recovered under both aeration and non-aeration conditions, of which aeration-free activation was more feasible on account of its energy-saving property. This study provides important information for the storage and transportation of MBGS in wastewater treatment.

Abstract
A Gram-stain-negative, non-motile, yellow-pigmented and non-spore forming rod-shaped bacterium, designated strain BN140078T, was isolated from farmland soil, Chungbuk, Republic of Korea. It was able to grow aerobically at 10-40 °C (optimum 28 °C), pH 5.5-7.5 (optimum pH 7.0) and with 0-2.0% (w/v) NaCl concentration (optimum 1.0%) on Reasoner's 2A (R2A) agar medium. Comparative 16S rRNA gene sequence analysis showed that the strain BN140078T had 96.9%, 96.5% and 96.1% 16S rRNA gene similarities with Chitinophaga ginsengihumi KACC 17604T, Chitinophaga rupis KACC 14521T and Chitinophaga japonensis KACC 12057T, respectively. The predominant respiratory quinone was menaquinone MK-7 and the major fatty acids (≥ 5%) were C16:1 ω5c, iso-C15:0, iso-C17:0 3-OH and Summed Feature 3 (C16:1 ω7c and/or C16:1 ω6c). The polar lipids were composed of phosphatidylethanolamine, four unidentified amino lipids and six unidentified lipids. The genomic DNA G+C content was 49.5 mol%. The genome of strain BN140078T comprises a number of biosynthetic gene clusters for secondary metabolites, in particular those for non-ribosomal peptide products. The polyphasic taxonomic study clearly distinguished this strain from its closest phylogenetic neighbors. Thus, we propose that the BN140078T represents a novel species of the genus Chitinophaga, for which the name Chitinophaga agrisoli sp. nov. was proposed. The type strain is BN140078T (=KCTC 62555T = CCTCC AB 2018162T).

Abstract
The excessive accumulation of organic matter (OM) in sediments in aquaculture ponds is a potential environmental threat due to the risk of endogenous water pollution and eutrophication. From the perspective of inhibiting OM accumulation to prevent endogenous water pollution, the present study investigated the OM degradation states, variations of bacterial communities and basic environmental factors in sediments with/without Macrobrachium nipponense treatment/control groups in triplicate for effects of bioturbation on OM degradation in 90-day incubation. The total organic carbon (TOC) and total nitrogen (TN) in the M. nipponense treatment were higher than in the control at the 30th and 60th days, while no significant differences between treatment and control were found at the end of the experiment. Significantly higher oxidation-reduction potential (ORP) and more extensively degraded OM were observed in the M. nipponense treatment. Eleven significantly differential bacterial taxa were enriched in the sediments of M. nipponense treatment, of which eight (Actinobacteria, Chitinophagales, Chitinophagaceae, Flavihumibacter, Marinilabiliaceae, Cytophaga xylanolytica group, Christensenellaceae, and Christensenellaceae R-7 group) were significantly correlated with at least two OM degradation indicators. The functional groups chemoheterotrophy, aerobic chemoheterotrophy, xylanolysis, ureolysis, and intracellular parasites were enhanced by M. nipponense and were negatively correlated with OM degradation indictors. Overall, the M. nipponense bioturbation effectively increased the ORP to provide better conditions for OM degradation, altered the taxonomic composition and functional groups to enhance the bacterial ability for OM degradation, and finally promoted the OM degradation of the surface sediment in an artificial aquaculture system.

Abstract
Aerobic granular sludge is considered one of the most promising biological wastewater treatment technologies of the 21st century. However, the long granulation time and poor treatment effect on N and P have severely limited its popularity and large-scale application. In this study, we systematically examine the strengthening effects of zeolite powder on granulation, N and P removal, and their interaction mechanisms. The addition of zeolite powder decreased sludge granulation time to 18 d, and improved average N and P removal rates by 4.48% and 2.22%, respectively. The multi-pore and nutrient-rich environment of the zeolite powder is beneficial for maintaining microbial activity and granular stability. Moreover, its adsorption to N and P enriches their respective removal strains, improving their removal efficiency.

Abstract
A Gram-stain-negative, yellow-pigmented, aerobic, non-spore-forming, motile with a single polar flagellum and rod-shaped bacterium, Ji-3-8T, was isolated from a soil sample taken from Jiri Mountain, Republic of Korea. Comparative 16S rRNA gene sequence studies showed the isolate had clear affiliation with Alphaproteobacteria and the closest relatedness to Caulobacter rhizosphaerae KCTC 52515T, Caulobacter henricii ATCC 15253T, Caulobacter segnis ATCC 21756T, Caulobacter hibisci THG-AG3.4T, Caulobacter flavus RHGG3T and Caulobacter vibrioides CB51T showing 99.1, 98.9, 97.7, 97.6, 97.5 and 97.4 % 16S rRNA gene sequence similarity, respectively, and 94.7-96.5 % to the remaining species of genus Caulobacter. The predominant ubiquinone was Q-10 and the major fatty acids were C18 : 1 ω7c 11-methyl, C16 : 0, summed feature 8 (C18 : 1 ω6c and/or C18 : 1 ω7c) and summed feature 3 (C16 : 1 ω6c and/or C16 : 1 ω7c). The major polar lipids were found to be phosphatidylglycerol, two unidentified phosphoglycolipid and two unidentified glycolipids. The G+C content of the genomic DNA of strain Ji-3-8T was 68.1 mol%. Average nucleotide identity and digital DNA-DNA hybridization values of strain Ji-3-8T with C. rhizosphaerae KCTC 52515T, C. henricii ATCC 15253T, C. segnis ATCC 21756T, C. flavus RHGG3T and C. vibrioides were 79.7-87.7% and 23.0-34.3%, respectively. Based on the polyphasic evidence, it is proposed that strain Ji-3-8T forms a novel species in the genus Caulobacter, for which the name Caulobacter soli sp. nov. is proposed. The type strain is Ji-3-8T (=CCTCC AB 2019389T=KCTC 72990T).

Abstract
A polyphasic taxonomic study was carried out on strains CHu50b-3-2T and CHu40b-3-1 isolated from a 67 cm-long sediment core collected from the Daechung Reservoir at a water depth of 17 m, Daejeon, Republic of Korea. The cells of the strains were Gram-stain-negative, non-spore-forming, non-motile and rod-shaped. Comparative 16S rRNA gene sequence studies showed a clear affiliation of two strains with γ-Proteobacteria, which showed the highest pairwise sequence similarities to
Lysobacter hankyongensis
KTce-2T (96.5 %),
Lysobacter pocheonensis
Gsoil193T (96.3 %),
Lysobacter ginsengisoli
Gsoil 357T (96.1 %),
Lysobacter solanacearum
T20R-70T (96.1 %),
Lysobacter brunescens
KCTC 12130T (95.4 %) and
Lysobacter capsici
YC5194T (95.3 %). The phylogenetic analysis based on 16S rRNA gene sequences showed that the strains formed a clear phylogenetic lineage with the genus
Lysobacter
. The major fatty acids were identified as summed feature 9 (iso-C17 : 1
ω9c and/or C18 : 1 10-methyl), iso-C15 : 0, iso-C16 : 0 and iso-C17 : 0. The respiratory quinone was identified as ubiquinone Q-8. The major polar lipids were phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine and an unidentified phospholipid. The genomic DNA G+C content was determined to be 66.8 mol% (genome) for strain CHu50b-3-2T and 66.4 mol% (HPLC) for strain CHu40b-3-1. Based on the combined genotypic and phenotypic data, we propose that strains CHu50b-3-2T and CHu40b-3-1 represent a novel species of the genus
Lysobacter
, for which the name Lysobacter profundi sp. nov. is proposed. The type strain is CHu50b-3-2T (=KCTC 72973T=CCTCC AB 2019129T). Besides
Lysobacter panaciterrae
Gsoil 068T formed a phylogenetic group together with strain
Luteimonas aquatica
RIB1-20T (EF626688) that is clearly separated from all other known
Lysobacter
strains. Based on the phylogenetic relationships together with fatty acid compositions,
Lysobacter panaciterrae
Gsoil 068T should be reclassified as a member of the genus Luteimonas: Luteimonas aquatica comb. nov. (type strain Gsoil 068T=KCTC 12601T=DSM 17927T).

Abstract
A novel Gram-stain-positive bacterial strain, CHu50b-6-2T, was isolated from a 67-cm-long sediment core collected from the Daechung Reservoir at a water depth of 17 m, Daejeon, Republic of Korea. The cells of strain CHu50b-6-2T were aerobic non-motile and formed yellow colonies on R2A agar. The phylogenetic analysis based on 16S rRNA gene sequencing indicated that the strain formed a separate lineage within the family Microbacteriaceae, exhibiting 98.0%, 97.7% and 97.6% 16S rRNA gene sequence similarities to Glaciihabitans tibetensis KCTC 29148T, Frigoribacterium faeni KACC 20509T and Lysinibacter cavernae DSM 27960T, respectively. The phylogenetic trees revealed that strain CHu50b-6-2T did not show a clear affiliation to any genus within the family Microbacteriaceae. The chemotaxonomic results showed B1α type peptidoglacan containg 2, 4-diaminobutyric acid (DAB) as the diagnostic diamino acid, MK-10 as the predominant respiratory menaquinone, diphosphatidylglycerol, phosphatidylglycerol, and an unidentified glycolipid as the major polar lipids, anteiso-C15:0, iso-C16:0, and anteiso-C17:0 as the major fatty acids, and a DNA G + C content of 67.3 mol%. The combined genotypic and phenotypic data showed that strain CHu50b-6-2T could be distinguished from all genera within the family Microbacteriaceae and represents a novel genus, Lacisediminihabitans gen. nov., with the name Lacisediminihabitans profunda sp. nov., in the family Microbacteriaceae. The type strain is CHu50b-6-2T (= KCTC 49081T = JCM 32673T).
