Plant growth-promoting characteristics of halotolerant endophytic bacteria isolated from Sporobolus specatus (Vahr) Kunth and Cyperus laevigatus L. of Ethiopian rift valley lakes. Arch Microbiol 2022; 204:403. [PMID: 35723754 DOI: 10.1007/s00203-022-03021-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2022] [Accepted: 05/25/2022] [Indexed: 11/02/2022]
Abstract
Understanding plant microbes' intimate relationship and search for beneficial microbes is a sustainable alternative to improve plant growth and yield under a wide range of biotic and abiotic stress conditions. More than 20% of the total global agricultural land is affected by salinity. High salinity challenges crop plants by affecting several metabolic pathways and decreasing plant growth and yield. Unlike chemical fertilizers and pesticides, endophytic microbes offer an eco-friendly approach to increasing crop yield via various metabolites during salinity stress. The objective of this study was to isolate and characterize endophytic halotolerant bacterial isolates from haloalkaliphytes, investigate their plant growth-promoting (PGP) properties and tolerance for various stress conditions. Sporobolus specatus (Vahr) Kunth and Cyperus laevigatus L. grass samples were collected from the shores of two Ethiopian soda lakes (Lakes Abijata, and Chitu, respectively). A total of 167 halotolerant endophytic bacterial isolates, that clustered into 21 ARDRA (Amplified ribosomal DNA restriction analysis) groups, affiliated to members of 11 bacterial genera, namely Halomonas, Agrobacterium, Exiguobacterium, Jonesia, Stenotrophomonas, Pseudomonas, Alishewanella, Kosakonia, Bacillus, Paracoccus and Pannonibacter, were identified based on 16S rRNA sequencing. Most of the strains were able to produce IAA (indole-3-acetic acid) and hydrogen cyanide, grow on a nitrogen-free medium and solubilize phosphate. In vitro tolerance tests reveal that isolates were tolerant to: 5.0-15% NaCl, up to 40% PEG 6000, temperatures up to 50 °C, and pH 5-11. These characteristics of the isolates indicate their potential PGP application under various plant stress conditions.

Folia Microbiol (Praha) 2021; 66:819-830. [PMID: 34148171 DOI: 10.1007/s12223-021-00886-w] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2020] [Accepted: 06/08/2021] [Indexed: 01/10/2023]
Abstract
Whey, the main by-product obtained from the manufacture of cheese, which contains a very high organic load (mainly due to the lactose content), is not easily degradable and creates concern over environmental issues. Hydrolysis of lactose present in whey and conversion of whey lactose into valuable products such as bioethanol, sweet syrup, and animal feed offers the possibility of whey bioremediation. The increasing need for bioremediation in the dairy industry has compelled researchers to search for a novel source of β-galactosidase with diverse properties. In the present study, the bacterium Paracoccus marcusii KGP producing β-galactosidase was subjected to morphological, biochemical, and probiotic characterisation. The bacterial isolate was found to be non-pathogenic and resistant to low pH (3 and 4), bile salts (0.2%), salt (10%), pepsin (at pH 3), and pancreatin (at pH 8). Further characterisation revealed that the bacteria have a good auto-aggregation ability (40% at 24 h), higher hydrophobicity (chloroform-60%, xylene-50%, and ethyl acetate-40%) and a broad spectrum of antibiotic susceptibility. The highest growth of P. marcusii KGP was achieved at pH 7 and 28 °C, and the yeast extract, galactose, and MgSO4 were the best for the growth of the bacterial cells. The bacterium KGP was able to utilise whey as a substrate for its growth with good β-galactosidase production potential. Furthermore, the β-galactosidase extracted from the isolate KGP could hydrolyse 47% whey lactose efficiently at 50 °C. The study thus reveals the potential application of β-galactosidase from P. marcusii KGP in whey bioremediation.

Abstract
Strain 11-3T was isolated from the surface seawater along the coast of Xiamen Island, China. Cells were Gram-stain-negative, oxidase- and catalase-positive, short and rod-shaped, nonmotile, 0.5-1.0 μm in width and 1.0-2.0 μm in length. Growth of strain 11-3T was at temperature of 15-37°C (optimum 28-35°C), at pH of 5.0-11.0 (optimum 7.0-9.0) and at salinity range of 0-10 (optimum 0.5-1). Phylogenetic analysis based on the 16S rRNA gene sequence indicated that strain 11-3T belonged to the genus Paracoccus and had the highest similarity with Paracoccus caeni MJ17T (98.1 %), followed by Paracoccus xiamenensis 12-3T (97.1 %), Paracoccus zeaxanthinifaciens ATCC 21588T (97.1 %), Paracoccus aestuarii DSM 19484T (97.0 %), Paracoccus liaowanqingii 2251T (97.0 %), Paracoccus fistulariae KCTC 22803T (97.0 %) and other species of the genus Paracoccus (95.2-96.8 %). The DNA-DNA hybridization values between strain 11-3T and the selected strains (P. caeni MJ17T, P. xiamenensis 12-3T, P. zeaxanthinifaciens ATCC 21588T, P. aestuarii DSM 19484T and P. liaowanqingii 2251T) were 19.4, 19.5, 21.6, 19.3 and 19.8 %, respectively. Corresponding, their ANI values were 77.53, 75.61, 75.36, 75.73 and 75.33 %, respectively. The major fatty acid was summed feature 8 (C18:1 ω6c/ω7c). The major respiratory quinone was Q10. The polar lipids included phosphatidylcholine (PC), phosphatidylethanolamine (PE), phosphatidylglycerol (PG), diphosphatidylglycerol (DPG), unidentified glycolipid (GL) and unidentified aminolipid (AL). The DNA G+C content of strain 11-3T was 60.1 %. Based on results of the phylogenetic analysis, phenotypic and chemotaxonomic characteristics, strain 11-3T represents a novel species of the genus Paracoccus, for which the name Paracoccus amoyensis sp. nov. is proposed. The type strain is 11-3T (=MCCC 1A16380T=KCTC 72689T).

Abstract
Strain 12-3T was isolated from seawater of the Guanyinshan Coast, Xiamen, Fujian Province, PR China. The bacterium was Gram-stain-negative, rod-shaped, aerobic, oxidase-positive and catalase-negative. Growth of strain 12-3T occurred at 10–37 °C (optimum, 20–30 °C), at pH 5.0–11.0 (optimum, pH 7.0–8.0) and at a salinity range of 0–10 % (optimum, 3–5 %). The results of phylogenetic analysis based on its 16S rRNA gene sequence indicated that strain 12-3T belonged to the genus
Paracoccus
and had the highest sequence similarity to
Paracoccus lutimaris
HDM-25T (97.4 %), followed by
Paracoccus isoporae
SW-3T (96.9 %),
Paracoccus caeni
MJ17T (96.9 %),
Paracoccus pacificus
F14T (96.8 %) and other species in the genus
Paracoccus
(95.3–96.5 %). The average nucleotide identity (ANI) and DNA–DNA hybridization (DDH) values between strain 12-3T and
P. lutimaris
HDM-25T were 76.1 and 17.0 %, respectively. ANI and DDH values between strain 12-3T and
P. isoporae
SW-3T were 78.9 and 18.2 %, respectively. The principal fatty acid of strain 12-3T was summed feature 8 (C18 : 1
ω6c/ω7c) and C18 : 0. The respiratory quinone of strain 12-3T was Q10. The polar lipids included phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and an unidentified glycolipid. The G+C content of the chromosomal DNA was 63.9 mol%. The combination of the results of the phylogenetic, phenotypic and chemotaxonomic analyses, and its low ANI and DDH values indicate that strain 12-3T represents a novel species of the genus
Paracoccus
, for which the name Paracoccus xiamenensis sp. nov. is proposed. The type strain is 12-3T (=MCCC 1A16381T=KCTC 72687T).

Abstract
Two strains, designated 2251T and 3058, that were aerobic, Gram-stain-negative, non-motile, coccoid or short rod-shaped bacilli, have recently been isolated from Tibetan antelopes on the Qinghai-Tibet Plateau. The results of phylogenetic analyses of 16S rRNA gene sequences indicated that strains 2251T and 3058 represent a new species within the genus Paracoccus and are most similar to 'Paracoccus gahaiensis' CUG00006T (98.9 and 99.3 %), Paracoccus nototheniae I-41R45T (98.3 and 98.7 %) and Paracoccus hibiscisoli THG-T2.31T (97.6 and 97.8 %). Results of genomic sequence-based phylogenomic analysis agreed with those from 16S rRNA gene sequence analysis. Optimal growth was achieved at pH 7.0-7.5 and 28 °C with marine medium. Cells contained C18 : 1 ω7c as the major cellular fatty acid and ubiquinone-10 as the predominant menaquinone. The polar lipids comprised phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol, phospholipid, glycolipid and an unidentified lipid. The cell-wall peptidoglycan amino acids were meso-2,6-diaminopimelic acid, alanine and glutamic acid; the major cell-wall sugar was galactose. The G+C content of strain 2251T was 66.5 mol%. Both strains (2251T and 3058) had DNA-DNA relatedness values less than 50 % with all available genomes of the genus Paracoccus in the ncbi database. Differential genotypic inferences, together with phenotypic and biochemical characteristics, demonstrated that strains 2251T and 3058 should be classified as a novel species of the genus Paracoccus, for which the name Paracoccus liaowanqingii sp. nov. is suggested. The type strain is 2251T (=CGMCC 1.16490T=DSM 106269T).

Abstract
A Gram-stain-negative and facultatively aerobic bacterium, designated as strain CBA4604T, was isolated from a traditional Korean salted and fermented shrimp food (saeu-jeot). Phylogenetic analysis based on 16S rRNA gene sequences showed that strain CBA4604T formed a clearly distinct phyletic lineage from closely related species within the genus Paracoccus. Strain CBA4604T was the most closely related to P. koreensis Ch05T (97.5% 16S rRNA gene sequence similarity) and other type strains (≤ 97.0%). The genome comprised a chromosome and two plasmids of 3,299,166 bp with 66.5% G+C content. The DNA-DNA relatedness values between strain CBA4604T and P. koreensis Ch05T, P. alcaliphilus DSM 8512T, and P. stylophorae KTW-16T were 30.5%, 22.9%, and 16.7%, respectively. Cells of the strain were short rod-shaped and oxidase- and catalase-positive. The growth of strain CBA-4604T was observed at 10-40°C (optimum, 37°C), pH 6.0-10.0 (optimum, pH 7.0), and in the presence of 0-8.0% (w/v) NaCl (optimum, 0-2.0%). Strain CBA4604T contained ubiquinone 10 as the sole isoprenoid quinone and summed feature 8 (C18:1ω7c/C18:1ω6c) and C18:0 as the major cellular fatty acids. The polar lipids consisted of phosphatidylcholine, phosphatidylglycerol, diphosphatidylglycerol, phospholipid, an unidentified aminolipid, an unidentified glycolipid, and three unidentified lipids. Based on its phylogenetic, genomic, phenotypic, and chemotaxonomic features, we concluded that strain CBA-4604T represents a novel species in the genus Paracoccus and we propose the name Paracoccus jeotgali sp. nov. The type strain is CBA4604T (= KACC 19579T = JCM 32510T).

Abstract
A Gram-stain-negative, aerobic, non-motile and coccoid or ovoid bacterial strain, designated LB2T, was isolated from a Korean foodstuff, salted pollack. Strain LB2T grew optimally at 25-30 °C, at pH 7.0-8.0 and in the presence of 0-2.0 % (w/v) NaCl. Phylogenetic trees based on 16S rRNA gene sequences showed that strain LB2T belonged to the genus Paracoccus, coherently clustering with the type strain of Paracoccus sulfuroxidans. Strain LB2T exhibited 16S rRNA gene sequence similarity values of 98.0 and 97.0 % to the type strains of P. sulfuroxidans and Paracoccus halophilus, respectively, and of less than 96.9 % to the type strains of other Paracoccus species. Strain LB2T contained Q-10 as the predominant ubiquinone. Major fatty acids of strain LB2T were cyclo C19 : 0ω8c, C18 : 1ω7c and C16 : 0 (when grown on MA) or C18 : 1ω7c and C16 : 0 (on TSA). The major polar lipids detected in strain LB2T were phosphatidylcholine, phosphatidylglycerol, diphosphatidylglycerol, one unidentified aminolipid and one unidentified glycolipid. The DNA G+C content of strain LB2T was 61.4 mol% and its DNA-DNA relatedness values with the type strains of P. sulfuroxidans and P. halophilus were 26 and 18 %, respectively. Differential phenotypic properties, together with its phylogenetic and genetic distinctiveness, revealed that strain LB2T is separated from recognized Paracoccus species. On the basis of the data presented, strain LB2T is considered to represent a novel species of the genus Paracoccus, for which the name Paracoccus alimentarius sp. nov. is proposed. The type strain is LB2T (=KCTC 62138T=NBRC 113023T).
