Although bioremediation is considered the most environmentally friendly and sustainable technique for remediating contaminated soil water, it effective when combined with physicochemical methods, which allow preliminary removal of large quantities pollutants. This allows microorganisms to efficiently eliminate remaining contaminants. In addition requiring necessary genes degradation pathways specific substrates, as well tolerance adverse environmental conditions, may perform below expectations. One typical reason this high toxicity xenobiotics present in concentrations, stemming from vulnerability bacteria introduced a site. especially true planktonic bacteria, whereas within biofilms or microcolonies have significant advantages over their counterparts. A physical matrix essential formation, maintenance, survival bacterial biofilms. By providing such immobilization, formation can be facilitated accelerated. Therefore, immobilization offers comprehensive solution cleanup by harnessing specialized metabolic activities while ensuring retention efficacy at target sites. many cases, also need methods that are otherwise required initially reduce contaminant concentrations. Then, will possible use remediation higher concentrations xenobiotics, significantly reducing costs maintaining rapid rate processes. review explores benefits highlighting materials processes developing an optimal matrix. It focuses on following four key areas: (i) types organic pollutants impacting human health, (ii) strains used processes, (iii) (iv) cells various carriers targeted pollutant degradation.

This study aimed to assess the impact of radish sprouts on gut microbiota healthy individuals. Radish sprout additives, subjected short-term storage and steam treatment, were used intervene in an vitro culture human microbiota. The influence was evaluated by monitoring short-chain fatty acid (SCFA) content proportion fermentation broth, microbial diversity assessed using 16S rDNA amplicon sequencing. results indicated that produced a substantial amount SCFA within 48 h fermentation, with right-skewed distribution across all groups. addition both digestates enhanced Firmicutes diversity, while Bacteroidetes Proteobacteria remained stable between control fresh 30 s treatment group showed increase decrease diversity. abundance Bacilli, Bacillaceae, Bacillus significantly higher steam-treated groups compared control. Both enriched showing superior effects. These findings suggest consumption may positively microbiota, potentially enhancing these benefits.

Arbuscular Mycorrhizal Fungi and Rhizobium Improve Nutrient Uptake and Microbial Diversity Relative to Dryland Site-Specific Soil Conditions

Microorganisms, Год журнала: 2024, Номер 12(4), С. 667 - 667

Опубликована: Март 27, 2024

Arbuscular mycorrhizal fungi (AMF) and rhizobium play a significant role in plant symbiosis. However, their influence on the rhizosphere soil microbiome associated with nutrient acquisition health is not well defined drylands of Montana (MT), USA. This study investigated effect microbial inoculants as seed treatment pea yield, uptake, potential functions, communities using high-throughput sequencing 16S ITS rRNA genes. The experiment was conducted under two contrasting dryland conditions four treatments: control, single inoculation AMF or Rhizobium, dual inoculations Rhizobium (AMF+Rhizobium). Our findings revealed that efficacy site-specific. AMF+Rhizobium synergistically increased grain yield at Sidney field site (DFS) 2, while Froid site, DFS 1, improved resilience to acidic but contributed marginal non-nutrient limiting conditions. Across sites, plants’ dependency (12%) higher than (8%) (4%) alone. Variations community structure composition indicate site-specific response inoculants. Overall, factors significantly influenced dynamics, functional potential. It underscores need for tailored management strategies consider characteristics optimize benefits from inoculation.

This study investigated the effects of citrus flavonoids (CF) and compared to antibiotics on piglet growth gut health. Weaned piglets were fed either a basal diet (CON) or supplemented with 75 mg/kg chlortetracycline (CTC), 20 CF (CF1), 40 (CF2), 80 (CF3). The group, especially CF3, exhibited improved performance; reduced diarrhea; significantly higher levels serum factors, immunoglobulins, anti-inflammatory cytokines; lower pro-inflammatory factors markers intestinal barrier damage (

Background: Polysaccharide metal chelate exhibit both immunoregulatory activity and element supplementation effects. Methods: In this study, Ruoqiang jujube polysaccharide copper (RJP-Cu) was prepared the preparation conditions were optimized using response surface method. Subsequently, RJP-Cu administered to lambs evaluate its impact on growth performance, ion (Cu 2+ ) supplementation, immune enhancement, intestinal flora evaluated. Results: The results indicated that optimal chelation included a sodium citrate content of 0.5 g, reaction temperature 50°C, solution pH 8.0, resulting in Cu concentration 583°mg/kg RJP-Cu. Scanning electron microscopy (SEM) revealed significant structural changes RJP before after chelation. displaying characteristic peaks polysaccharides chelates. Blood routine indexes showed no differences among RJP-Cu-High dose group (RJP-Cu-H), RJP-Cu-Medium (RJP-Cu-M), RJP-Cu-low (RJP-Cu-L) control ( p > 0.05). However, compared with group, RJP-Cu-H, M, L groups significantly enhanced lamb production performance < Furthermore, increased serum concentration, total antioxidant capacity (T-AOC), catalase (CAT), superoxide dismutase (T-SOD) contents RJP-Cu-H exhibited increases IgA IgG antibodies, as well secretion cytokines IL-2, IL-4, TNF-α (p species abundance microbiota, quantity beneficial bacteria, decrease harmful bacteria. led promotion synthesis various Short Chain Fatty Acids (SCFAs), improvements atrazine degradation clavulanic acid biosynthesis lambs, while reducing cell apoptosis lipopolysaccharide biosynthesis. Conclusion: Thus, these findings demonstrate RJP-Cu, chelate, could effectively promote increase content, potentially induce positive immunomodulatory effects by regulating enzymes, cytokines, flora, related metabolic pathways.

Elucidating the structure, and composition of bacterial symbionts in the gut regions of wood-feeding termite, Coptotermes formosanus and their functional profile towards lignocellulolytic systems

Frontiers in Microbiology, Год журнала: 2024, Номер 15

Опубликована: Май 22, 2024

The wood-feeding termite, Coptotermes formosanus, presents an efficient lignocellulolytic system, offering a distinctive model for the exploration of host-microbial symbiosis towards lignocellulose degradation. Despite decades investigation, understanding diversity, community structure, and functional profiles bacterial symbionts within specific gut regions, particularly foregut midgut C. remains largely elusive. In light this knowledge gap, our efforts focused on elucidating composition functions symbiotic bacteria inhabiting foregut, midgut, hindgut formosanus via metagenomics. termite harbored diverse encompassing 352 genera 26 known phyla, exhibiting uneven distribution across regions. Notably, displayed higher relative abundance phyla such as Bacteroidetes (56.9%) Spirochetes (23.3%). contrast, were predominantly occupied by Proteobacteria (28.9%) Firmicutes (21.2%) after Bacteroidetes. unique like Candidate phylum_TM6 Armatimonadetes. At family level, Porphyromonadaceae (28.1, 40.6, 53.5% in hindgut, respectively) Spirochaetaceae (foregut = 9%, 16%, 21.6%) emerged dominant families termite's Enriched operational taxonomic units (OTUs) most abundant (28), followed (14), while exhibited enrichment only two OTUs. Furthermore, analyses revealed distinct influences various metabolic pathways, carbohydrate energy metabolisms host. Overall, these results underscore significant variations structure among different regions suggesting roles bacteria, thereby inspiring further investigations to resolve crosstalk between host microbiomes individual gut-regions termite.
