“…Recent studies have shown that Sphingobacteriaceae has the ability to degrade zearalenone and vomitoxin (He, 2017). Novosphingobium species are renowned for their ability to adapt metabolically and their significant potential for effectively addressing pollution challenges (Liu et al 2021;Chen et al 2021). So it is hypothesized that Novosphingobium sp.…”

Novosphingobium species are Gram-negative, rod-shaped bacteria containing sphingoglycolipids. In this study, Novosphingobium species were isolated and characterized based on morphology and biochemical analysis. The research also investigated the impact of different culture media, temperature, time and pH on the growth of Novosphingobium species, aiming to determine its optimal growth kinetics. The culture media (LB, 0.1% glucose LB, NB, 0.1% glucose NB, and MM), pH (4, 5, 6, 7, 8, 9 and 10), and incubation temperatures (25, 30, 37, 45, and 55Â°C), were examined for representative Novosphingobium sp. growth, measured as optical density (OD). The results indicated that all the strains displayed yellow colony morphology with rounded raised edges and smooth surfaces. Strains were rod-shaped without spore production. All the strains assimilated maltose, sucrose, xylose and oxidized glucose. Representative strain of Novosphingobium species grown rapidly on 0.1% glucose LB medium and optimal temperature were identified 37Â°C. The growth of representative strain was significantly influenced by the initial pH of the culture media, but 7 pH was identified as optimal. This study provides valuable information regard74ing the characterization and optimal growth conditions of Novosphingobium species.

Members of the genus Novosphingobium were frequently isolated from polluted environments and possess great bioremediation potential. Here, three species, designated B2637T, B2580T and B1949T, were isolated from mangrove sediments and might represent novel species in the genus Novosphingobium based on a polyphasic taxonomy study. Phylogenomic analysis revealed that strains B2580T, B1949T and B2637T clustered with Novosphingobium naphthalenivorans NBRC 102051T, ‘ N. profundi ’ F72 and N. decolorationis 502str22T, respectively. The average nucleotide identity (ANI) and digital DNA–DNA hybridization (dDDH) values between isolates and their closely related species were less than 94 and 54 %, respectively, all below the threshold of species discrimination. The sizes of the genomes of isolates B2580T, B2637T and B1949T ranged from 4.4 to 4.6 Mb, containing 63.3–66.4 % G+C content. Analysis of their genomic sequences identified genes related to pesticide degradation, heavy-metal resistance, nitrogen fixation, antibiotic resistance and sulphur metabolism, revealing the biotechnology potential of these isolates. Except for B2637T, B1949T and B2580T were able to grow in the presence of quinalphos. Results from these polyphasic taxonomic analyses support the affiliation of these strains to three novel species within the genus Novosphingobium , for which we propose the name Novosphingobium album sp. nov. B2580T (=KCTC 72967T=MCCC 1K04555T), Novosphingobium organovorum sp. nov. B1949T (=KCTC 92158T=MCCC 1K03763T) and Novosphingobium mangrovi sp. nov. B2637T (KCTC 72969T=MCCC 1K04460T).
