Extracts of N. lutea have been reported for multiple biological functions such as antimicrobial, antileishmanial, anti-inflammatory, and antitumor activities (Table 4.27). In vitro studies revealed the broad-spectrum antibacterial activity of the leaf extracts against numerous bacteria (Aeromonas hydrophila, E. faecalis, Enterobacter cloacae, Lactococcus garvieae, P. aeruginosa, P. vulgaris, S. aureus, S. epidermidis, S. agalactiae, and Yersinia ruckeri). The flowers of N. lutea showed inhibitory effects on the growth of a Gram-negative bacterium (E. coli) and a pathogenic yeast (C. albicans) (Gillitzer et al. 2012, Turker et al. 2009, Yildirim et al. 2013).

Multiple microbial species are known to possess isoflavone-metabolizing daidzein reductase (DR) dihydrodaidzein reductase (DHDR) and tetrahydrodaidzein reductase (THDR) genes. The nucleotide sequences of these genes from Adlercreutzia equolifaciens (DR: RFT81436.1 DHDR: RFT81438.1 THDR: RFT81439.1) Eggerthella sp. YY7918 (DR: BAK44713.1 DHDR: BAK44715.1 THDR: BAK44716.1) Lactococcus garvieae (DR: BAJ72750.1 DHDR: BAJ72748.1 THDR: BAJ72744.1) Senegalimassilia sp. KGMB04484 (DR: RXZ54824.1 DHDR: RXZ54822.1 THDR: RXZ54821.1) Slackia equolifaciens (DR: RNL39925.1 DHDR: RNL39927.1 THDR: RNL39927.1) Slackia sp. NATTS (DR: BAL46930.1 DHDR: BAL46929.1 THDR: BAL46928.1) and Slackia isoflavoniconvertens (DR: AFV15453.1 DHDR: AFV15451.1 THDR: AFV15450.1) were obtained from NCBI. We also obtained the daidzein and genistein reductase (dgr) gene (KJ452760.1) from Slackia sp. AUH-JLC159 and combined with DR DHDR and THDR genes from the aforementioned bacterial species to create a custom database. The assembled fecal metagenomes from each mouse were searched for the presence of isoflavone-metabolizing genes in a custom database using nucmer with default parameters.63 Similarly bacterial reference genomes of B. adolescentis (NZ_CP028341.1) B. longum (NZ_AKCA01000001.1) and B. stellenboschense (NZ_JGZP01000001.1) were obtained from NCBI and searched for the presence of isoflavone-metabolizing genes.

We reconstruct multilayer networks at each position from which we can trace how coarse- and fine-grained networks vary along biogeographical gradients (Figures 7, 8). For the UC group, coarse-grained networks are structurally very similar over seven sampled positions, except for the link from modules M6 to M1, which is commensalistic at lumen, cecum, and ileum but amensalistic at transverse colon, descending colon, sigmoid colon, and rectum (Figure 7). Fine-grained networks also vary among gut positions, but with the degree of this difference depending on modules. Network communities for M4 and M6 exhibit a slight increase of commensalism strength from lumen to rectum, but those for M1, M2, M3, M5, and M7 differ dramatically among positions. In those network communities, some species-species links change from commensalism to amensalism. For example, in M5, Bacteroides plebeius and Sutterella wadsworthesis are mutualistic to each other at lumen, cecum, and ileum, but become increasingly parasitic from transverse colon to descending colon to sigmoid colon to rectum. Similarly, in M3, Lactobacillus coryniformis is commensalistic to Lactococcus garvieae at lumen and cecum, but this relationship becomes amensalistic with an increasing strength from ileum to transverse colon to descending colon to sigmoid colon to rectum.

Currently, rainbow trout production occupies an important place in freshwater fish farming practices around the world (Galezan et al., 2020; Terzi et al., 2020); In rainbow trout (Oncorhynchus mykiss), bacterial diseases have a great impact in economics and animal health. The major bacteria associated with fish diseases are the Gram-negative Aeromonas hydrophila, Aeromonas salmonicida, Yersinia ruckeri, Flavobacterium psychrophilum and Pseudomonas spp. and the Gram-positive Lactococcus Garvieae, Streptococcus spp. and Staphylococcus spp. (Corum et al., 2018; Quesada et al., 2013; Samuelsen, 2006; Sekkin & Kum, 2011).
