“…Then, the amplification and sequencing of the V3–V4 region of the 16S rRNA gene were outsourced to LC-Biotechnology Corporation (Zhejiang, China), which were performed on NovaSeq PE250 platform. The primers and procedures of PCR amplification and sequencing were as described by Wang et al (2023) . All generated raw data in this study was deposited in the National Center for Biotechnology Information Sequence Read Archives (Program accession no.…”

Endosymbiotic bacteria (ESB) have important effects on their hosts, contributing to its growth, reproduction and biological functions. Although the effects of exogenous bacteria on the trap formation of nematode-trapping fungi (NTF) have been revealed, the effects of ESB on NTF remain unknown. In this study, we investigated the species diversity of ESB in the NTF Arthrobotrys musiformis using high-throughput sequencing and culture-dependent approaches, and compared bacterial profiles to assess the effects of strain source and culture media on A. musiformis. PICRUSt2 and FAPROTAX were used to predict bacterial function. Our study revealed that bacterial communities in A. musiformis displayed high diversity and heterogeneity, with Proteobacteria, Firmicutes, Bacteroidetes and Actinobacteria as the dominant phyla. The ESB between A. musiformis groups isolated from different habitats and cultured in the same medium were more similar to each other than the other groups isolated from the same habitat but cultured in different media. Function analysis predicted a broad and diverse functional repertoire of ESB in A. musiformis, and unveiled that ESB have the potential to function in five modules of the nitrogen metabolism. We isolated nitrogen-fixing and denitrifying bacteria from the ESB and demonstrated their effects on trap formation of A. musiformis. Among seven bacteria that we tested, three bacterial species Bacillus licheniformis, Achromobacter xylosoxidans and Stenotrophomonas maltophilia were found to be efficient in inducing trap formation. In conclusion, this study revealed extensive ESB diversity within NTF and demonstrated that these bacteria likely play important roles in nitrogen cycling, including nematode trap formation.

“…Patterned substrates endow interfacial polymerized films with unique morphologies and properties. The patterned topography replicated by a thin polyamide selective layer results in an enlarged active surface area, improved hydrodynamic effect, and even more effective conduction pathway, 110 which facilitates high permeance and long-term fouling mitigation in economical and stable liquid separation. To obtain intact and dense polymers on such interfaces, various methods have been employed, such as increasing the concentration of monomers, prolonging the reaction time, or carrying out layered or repeated interfacial polymerization.…”

“…The innumerable health benefits of tea have been attributed to its potent antioxidant activity. The antioxidant activity of tea leaves or green tea is primarily attributed to the flavonoids, more specifically, the catechin content [39][40][41][42]. Therefore, flavonoids can be termed as a biological antioxidant, which is defined as "any substance that when present at low concentrations compared to those of an oxidizable substrate, significantly delays or prevents oxidation of that substrate" [27].…”

Tocklai vegetative (TV) cultivars are extensively planted in the tea-growing regions of Northeast India. The present investigation explores the impact of season on the total polyphenol (TP) content and the antioxidant activity of thirty-one TV cultivars (TV1–TV31) and four other commercially popular cultivars, namely, Betjan, Kharijan, S.3A/3, and T.3E/3. The TP content of the cultivars was observed to be highest in the monsoon season, with values ranging from 230.57 to 283.53 mg g−1. In the pre-monsoon season and autumn, the TP content ranged from 197.87 to 256.77 mg g−1 and from 169.97 to 223.50 mg g−1, respectively. Antioxidant activity was measured through DPPH, ABTS, FRAP, and lipid peroxidation inhibition assays. The cultivars showed the highest antioxidant activity in the monsoon in tandem with TP content. A bivariate correlation indicated a highly significant (p ≤ 0.01) positive correlation of antioxidant activity with TP content (R2 = 0.83–0.96).
